I need a project management tool that is one-time purchase and does not require a monthly subscription.

Yes. If your priority is pay once, keep using it, and avoid monthly subscriptions, there are several good options.

My top picks

• omnigroup.com — Probably the strongest traditional project-management choice. The perpetual license is $199.99 for Standard or $399.99 for Pro. You own the purchased version permanently, with all 4.x updates included. It is especially good for Gantt charts, dependencies, scheduling, and resource planning.
• plannedit.app — A Windows desktop app with Kanban, Gantt charts, task management, calendars, recurring tasks, templates, and CRM. It uses a one-time-purchase model with no monthly or per-user fees. It also has a permanent free tier.
• darilpm.com — More appropriate for serious/complex project management. $149 one-time for the core version or $249 one-time for DARIL+, with the purchased version continuing to work after the included year of updates. It includes risks, issues, decisions, timelines, status reporting, and portfolio features.
• Tomoro — A much simpler option if you're primarily managing your own projects and tracking time. It's $49 one-time, works on Windows and macOS, and is designed to work locally without a cloud account.

If you want something like Microsoft Project

Microsoft Project-style software is still available with perpetual licenses, although you need to be careful about where you buy the license.

• Microsoft Project 2021 Standard License - $489.99 (MyChoiceSoftware.com)

For more advanced resource management and collaboration:

• Microsoft Project 2021 Professional - $589.99 (MyChoiceSoftware.com)

One caution: I'd favor buying directly from the software vendor when possible. Some third-party "lifetime Microsoft Project" offers are substantially cheaper, but their licensing legitimacy and support can be harder to establish.

What I'd choose

If you tell me Windows or Mac, number of users, and whether you need Gantt charts/Kanban/resource management, I can narrow this down to the best 2–3 options under a specific one-time budget.

Finding a traditional, cloud-based project management tool (like Asana or Monday.com) that offers a one-time purchase is tough, because the industry has heavily shifted to Software-as-a-Service (SaaS) monthly subscriptions.

However, you still have great options depending on whether you want locally installed desktop software , a self-hosted server solution , or lifetime templates:

1. Traditional Desktop Software (One-Time Local License)

• Microsoft Project (Standard or Professional 2024)
  • What it is: The classic desktop application for deep scheduling, Gantt charts, cost tracking, and workload management.
  • The deal: Available as a traditional, one-time perpetual purchase. You buy it once, install it on a single PC, and own the license forever with no recurring subscription.
  • Best for: Traditional, complex project planning on a single machine (note that lower-tier editions lack heavy online team collaboration). You can check options on the Microsoft Project Guide via ProjectManager.com.

2. Open-Source & Self-Hosted (Free Software, Pay-Once Support/Hosting)

If you have a local server or a private cloud (or a cheap $5/month VPS), open-source tools allow you to host your own project management environment with zero licensing subscription fees.

• Redmine
  • What it is: A flexible, open-source project management and issue-tracking web application. It includes Gantt charts, calendars, role-based access, and multiple project support.
  • The deal: Completely free and open source. You host it on your own hardware, meaning your only cost is your own server setup or a one-time setup fee if you hire someone to configure it. Learn more on the official Redmine Website.
• OpenProject
  • What it is: A robust, enterprise-ready open-source project management system supporting both classic (Waterfall) and agile methodologies.
  • The deal: The community edition is free to self-host on-premises. If you want commercial-grade enterprise plugins with dedicated backing, they sell fixed on-premises enterprise licenses. Explore capabilities on OpenProject.

3. Workspace Templates (Buy Once, Run on Free Software)

• Notion Lifetime Systems / Second Brain Templates
  • What it is: Comprehensive project management systems built entirely inside Notion by independent creators.
  • The deal: You pay a single, one-time fee to a creator for lifetime access to a custom database template, and run it inside Notion’s free tier (no monthly Notion subscription required for personal/small use).

To help me narrow down the best fit , let me know:

• Are you managing projects completely solo or with a team?
• Do you prefer a local desktop app , or do you have a server/technical setup to self-host?

Yes. There are still several good one-time-purchase project management tools—you don't have to accept a monthly SaaS subscription.

My top picks

• OmniPlan — $199.99 Standard / $399.99 Pro, one-time purchase. Excellent if you use Apple devices and want serious Gantt charts, dependencies, scheduling, and resource planning. The license is perpetual for that major version.
• CrossOff — $19.99 one time. Much simpler: projects, tasks, priorities, due dates, and an offline desktop app for Windows, Mac, and Linux. Your data stays locally on your computer.
• DARIL — $149 one time for the Core version or $249 for DARIL+. This is the most interesting option if you're managing complex professional projects with risks, issues, decisions, deliverables, timelines, reporting, and audit history. One year of updates is included; your purchased version continues working afterward.
• Nullo — currently $12 one time. It's an offline project/portfolio planner with Gantt timelines, Kanban, resource planning, calendars, and dashboards. It's particularly appealing if you want something inexpensive and private, although it's designed for a single user, not live team collaboration.
• Microsoft Project perpetual license — still an option if you specifically want the traditional Microsoft Project environment. Be careful to distinguish the one-time perpetual versions from Microsoft's subscription offerings.

What I'd choose

If you tell me (1) Windows/Mac, (2) solo or team, (3) whether you need Gantt charts, and (4) your approximate budget, I can narrow this down to the best 2–3 choices and specifically exclude anything that sneaks in a subscription.

Finding a traditional, off-the-shelf project management tool with a one-time purchase model is genuinely tricky nowadays, as almost the entire industry has shifted to cloud-based SaaS subscriptions. However, depending on whether you are looking for local desktop software, a self-hosted server solution, or a comprehensive template, a few solid options fit the bill:

• Desktop Software: Microsoft Project Professional 2024 is available as a traditional one-time perpetual license. You pay once to install it locally on a single PC, giving you robust scheduling, resource management, and Gantt charts without any recurring subscription.
• Time & Work Tracking: actiTIME Self-Hosted offers a one-time payment option per user rather than a recurring subscription. It specializes heavily in task tracking, scope management, and billing.
• Open-Source / Self-Hosted: Redmine is a completely free, open-source project management web application. While it isn't an "out-of-the-box" commercial product you buy with a single click—you have to host and maintain it on your own server—it costs $0 forever and requires zero subscription fees.
• Ecosystem Templates: Pre-built Notion or Airtable Systems (sold by independent creators as lifetime digital products) let you run advanced project management databases, client trackers, and kanban boards entirely on the Notion or Airtable free tiers, meaning a single one-time template fee from a marketplace is all you ever pay.

To help narrow down the best choice, let me know:

• Are you managing projects solo or with a team?
• Do you prefer a local desktop app , a self-hosted server , or a template/cloud-free workaround?
• What core features do you need most (e.g., Gantt charts, Kanban boards, time tracking)?

Yes. If your priority is “pay once and never have a monthly subscription,” there are several good options. I’d narrow it down based on whether you need desktop scheduling, team collaboration, or a simpler task/Kanban system.

My top picks

• omnigroup.com — best polished desktop option

• $199.99 Standard / $399.99 Pro, one-time purchase.

• Perpetual license: you keep that version forever.

• Strong Gantt charts, dependencies, resource planning, and scheduling.

• Best if you're on Mac/iPhone/iPad.

• projectlibre.com — best free option

• $0 forever, open source.

• Windows, Mac, and Linux.

• Gantt charts, WBS, resource management, critical path, cost tracking, and Microsoft Project file compatibility.

• Particularly good if you want something resembling Microsoft Project without paying anything.

• darilpm.com — best modern “buy once” PM system

• $149 one-time for the Core version; $249 one-time for DARIL+.

• Includes registers for deliverables, actions, risks, issues, decisions, etc., plus timelines, reporting, and exports.

• Your purchased version continues working indefinitely; one year of updates is included, with renewal optional.

• More oriented toward project controls/governance than traditional Microsoft Project-style scheduling.

• conyso.com — interesting low-cost option

• Free browser version.

• Self-hosted perpetual license starting at $49 individual / $499 company, one-time.

• Focused heavily on CPM scheduling and construction/project scheduling rather than being an all-purpose PM platform.

What I'd choose

One important distinction: one-time purchase doesn't always mean you'll receive every future version free. For example, OmniPlan's perpetual license covers the purchased major version, while future major upgrades can cost extra.

If you tell me (1) Windows or Mac, (2) number of users, and (3) whether you need Gantt charts/resource management, I can narrow this to the best 2–3 choices under your budget.

Finding a traditional, dedicated project management SaaS tool (like Asana or Monday.com) that offers a permanent one-time purchase is difficult, as almost the entire industry has shifted to recurring subscriptions. However, depending on whether you want desktop software, a self-hosted open-source platform, or a lifetime marketplace deal, several great options fit your needs.

1. Traditional Desktop Software (Perpetual License)

• Microsoft Project Professional: If you need a powerful, offline-capable tool with Gantt charts, task dependencies, and resource management, the desktop version is available as a traditional one-time perpetual license [cite: 1.1.3]. Note that it is designed for Windows and doesn't have the real-time cloud collaboration of web apps, but you pay once and own it forever [cite: 1.1.3].

2. Self-Hosted / Open-Source (Zero Subscription Cost)

If you (or your team) have a server or local machine to host it on, open-source software gives you permanent, full-featured access for a one-time setup effort (though you pay for your own hosting infrastructure if online) [cite: 1.2.1].

• Redmine: A classic, highly reliable open-source project management and issue-tracking tool [cite: 1.2.1]. It includes time tracking, Gantt charts, role-based access, and wiki pages. Completely free to use forever on your own server [cite: 1.2.1].
• OpenProject: A feature-rich open-source project management system [cite: 1.2.2]. The Community Edition is free to self-host and provides robust classic and agile project management, task tracking, and team collaboration [cite: 1.2.2].
• Taiga: A gorgeous, agile-focused open-source project management tool [cite: 1.1.3]. It's exceptionally user-friendly for Kanban boards, sprint backlogs, and milestone tracking if you prefer a modern interface over older enterprise tools [cite: 1.2.2].

3. Lifetime Deals (SaaS with One-Time Pay Options)

Platforms occasionally offer lifetime access via software deal marketplaces (like AppSumo) or specific lifetime tiers:

• Flowlu: An all-in-one business and project management tool that frequently features lifetime access deals on software partner sites [cite: 1.1.3]. It handles project tracking, CRM, invoicing, and task management [cite: 1.1.3].
• Freedcamp: Offers robust free tiers [cite: 1.2.1] and occasional lifetime business upgrades through promotional partner networks, making it a scalable alternative to major subscription apps [cite: 1.2.1].

To help narrow down the best fit, tell me:

• Do you need local/offline desktop software or a team-collaborative web tool?
• Are you comfortable self-hosting on a server, or do you need a ready-to-go cloud app?
• What are the key features you need most (e.g., Kanban boards, Gantt charts, time tracking)?

Yes. There are still several project-management tools you can buy once instead of paying monthly. I’d narrow it to these:

My top picks

1. Best overall: DARIL At $149 one-time, it has deliverables, actions, risks, issues, decisions, backlog, timelines, dashboards, reporting and exports. The important part: your purchased version keeps working forever; the first year of updates is included, and renewing updates is optional.

2. Best traditional project-management software: OmniPlan If you want something closer to Microsoft Project—with Gantt charts, dependencies, scheduling and professional project planning—OmniPlan is a strong choice. Its perpetual Standard license is $199.99, and you own that version indefinitely.

3. Best bargain: Nullo If you don't need cloud collaboration, Nullo is unusually inexpensive: currently $12 one-time, with Gantt, Kanban/sprint boards, resource planning and dashboards. It runs locally/offline and doesn't require an account.

4. Best if you also need CRM: PlannedIt This combines CRM, Gantt charts, Kanban, calendars, tasks and project templates in a Windows desktop application. It has a free tier and a paid one-time license rather than a subscription.

If you tell me (1) Windows or Mac, (2) solo or team, (3) whether you need Gantt charts, and (4) your maximum budget, I can narrow this to the best 2–3 choices for you.

Finding a true one-time purchase project management tool can be tough, as most of the software industry has shifted entirely to monthly or annual SaaS subscriptions . However, depending on your operating system, team size, and whether you need heavy Gantt charts or lightweight task tracking, a few solid perpetual-license options still exist.

1. Traditional Enterprise & Advanced Planning (Windows / Mac)

• Microsoft Project Standard (On-Premises):
  • Best for: Heavy-duty, traditional waterfall project management, resource leveling, and detailed Gantt charts.
  • Pricing: One-time purchase (around $680 for the Standard desktop version).
  • Caveat: It’s expensive upfront, licensed per PC, and doesn't include modern real-time cloud collaboration out of the box like the enterprise subscription tiers.
• OmniPlan (Mac / iOS):
  • Best for: Mac-based professional project managers who want interactive Gantt charts, milestones, and critical path analysis.
  • Pricing: Perpetual license available (approx. $199 for Standard, $399 for Pro).
  • Caveat: Apple-ecosystem only (Mac, iPad, iPhone). You own that specific major version forever.

2. Personal & Solo Project Management (Apple Ecosystem)

• Things 3 (Mac / iOS):
  • Best for: Freelancers, creatives, and solo professionals practicing Getting Things Done (GTD). It handles projects, headings, tags, and deadlines brilliantly.
  • Pricing: One-time purchase per platform (e.g., Mac app is around $50; iOS sold separately). No subscription.
  • Caveat: Apple devices only (no Windows, Android, or web browser version).

3. Self-Hosted & Local Solutions (Platform Independent)

• Kendo Manager:
  • Best for: Small teams or individuals who want an on-premise, self-hosted web app where they control the server and data.
  • Pricing: One-time license fee that covers unlimited projects and includes a year of support/updates.
• Local Markdown/Kanban (Obsidian or Logseq):
  • Best for: Highly customizable, completely offline, privacy-first personal project management.
  • Pricing: Free, with optional one-time purchases for sync/commercial add-ons.
  • Caveat: Requires setting up your own folders, tags, and plugins (like Kanban boards) rather than opening an out-of-the-box corporate PM suite.

To help narrow down the best fit, could you tell me:

• Are you managing projects solo or with a team?
• What operating system/devices do you use (Windows, Mac, mobile)?

Finding a true one-time purchase or perpetual license project management tool can be tough, as almost the entire software industry has shifted to SaaS (monthly/yearly subscriptions). However, depending on whether you want a traditional desktop app, a self-hosted server solution, or a comprehensive template, a few solid options fit the bill.

• Microsoft Project Professional is a traditional desktop-based application installed locally on a Windows PC. It is licensed strictly as a one-time purchase, meaning you pay once to use that specific version indefinitely. It’s ideal for complex, Gantt-chart-heavy, and resource-driven engineering or construction projects, though it lacks native real-time cloud collaboration unless tied to enterprise servers.
• Jira (Self-Hosted / Data Center) offers a one-time payment option if you choose to host it on your own hardware or server rather than using Atlassian's cloud. Pricing scales based on the number of user tiers, making it an investment upfront, but it completely removes recurring cloud subscription fees once bought. It is heavily tailored toward software development and agile tracking.
• Open-Source & Self-Hosted Tools (Free/Self-Funded) like OpenProject [Redmine], or [Kanboard] are entirely free to run on your own local server or private cloud. While not a "commercial purchase," they completely eliminate subscriptions because you own the deployment and data entirely.
• Premium Notion Templates acting as a "Freelance or Business System" function as a one-time purchase. While Notion itself has subscription tiers for advanced team spaces, buying a comprehensive, pre-built project/client management template from independent creators gives you a powerful, customized database workspace for a single upfront cost.

To help narrow down the right choice, tell me:

• Are you looking for a local desktop app for an individual, or a server-hosted tool for a team?
• What key features do you need most (Kanban boards, Gantt charts, time tracking, bug tracking)?

Yes. There are still a few genuine buy-once project-management tools, although most mainstream SaaS products have moved to subscriptions.

My top picks

• omnigroup.com — $199.99 one-time for the Standard perpetual license, or $399.99 Pro. Excellent if you're on Mac/iPhone/iPad and want serious Gantt charts, dependencies, scheduling, and resource management. The purchase covers the entire 4.x version; major future versions are discounted rather than included. The Omni Group My pick for: professional project planning on Apple devices.
• planmancorp.com — currently $12 one-time. It includes Gantt planning, Kanban/sprint boards, resource planning, dashboards, and works completely offline with no account or subscription. It's a single-user local tool, so it's not suitable if you need live team collaboration. PlanManCorp My pick for: inexpensive, private, offline project management.
• darilpm.com — $149 one-time for Core or $249 for DARIL+, with one year of updates included. It's more oriented toward formal project governance—risks, issues, decisions, deliverables, baselines, timelines, status reporting, etc. Your purchased version continues working after the included update period. Daril My pick for: PMO-style/project-governance work.
• Microsoft Project Standard 2024 — $679.99 one-time directly from Microsoft, with Gantt charts, task/cost management, milestones, critical path, and resource leveling. Professional 2024 is $1,129.99. It's a traditional Windows desktop application rather than a subscription. Microsoft My pick for: organizations that specifically want the Microsoft Project ecosystem.

One interesting newer option

Vantage Plan is another buy-once project planner, with a reported one-time price around $130 for Basic and $300 for Pro, although its current site says it's still in development/final stages for the Mac App Store.

What I'd choose

One important caveat: Merlin Project is not a buy-once option anymore. Its developer explicitly discontinued perpetual licenses in 2026 and now requires a subscription.

If you tell me Windows or Mac, individual or team, and whether you need Gantt charts, Kanban, time tracking, or client collaboration, I can narrow this down to the best 2–3 options that genuinely don't require a subscription.
