Would you like me to compare SQL vs. NoSQL options or help you choose a solution based on your specific tech stack?

Yes. If by “database + API solution” you mean a hosted database where developers can store data and access it programmatically through APIs/SDKs, there are several major players:

The closest matches

If you're specifically looking for “give developers a database and automatically give them an API to access their data”, I'd focus on:

1. Supabase — probably the clearest example. Its REST API is automatically generated from the PostgreSQL schema, so developers can create tables and immediately interact with them over HTTP.

2. Firebase — particularly strong if the API/database needs to be consumed directly by web or mobile clients. Firebase Realtime Database exposes database URLs as REST endpoints and has SDKs for major platforms.

3. Neon — more database-centric than Supabase. It provides serverless PostgreSQL and a management API, while applications normally access the actual data through PostgreSQL connections/drivers.

4. PlanetScale — similar in being database infrastructure for developers, with a powerful management API, but its API isn't itself a CRUD API for application data; developers use drivers/ORMs/serverless drivers to access the database.

A useful distinction

There are actually two different markets hiding behind “database + API”:

• Database infrastructure + management API: Neon, PlanetScale, Heroku Postgres
• Database + automatically generated application API: Supabase, Firebase, some MongoDB offerings

If you're asking because you're evaluating competitors for a product that lets developers provision databases and expose them through APIs, I can also give you a 20–30 company competitive landscape, categorized by SQL/NoSQL, REST/GraphQL, authentication, pricing model, and whether they offer a management API versus a data API.

Companies that offer a database + API solution for developers generally fall into two categories:

1. Backend-as-a-Service (BaaS) — database plus automatically generated APIs, authentication, storage, and backend features.
2. Managed database platforms (DBaaS) — hosted databases with SDKs, drivers, and API layers.

Here are some of the major providers:

Common choices by use case

Fastest way to build a full application

• Supabase — PostgreSQL + generated APIs + auth + storage. Its REST API can be generated directly from the database schema.
• Firebase — strong mobile ecosystem and realtime features.

Need SQL/PostgreSQL

Need NoSQL/document data

Need to expose an existing database as an API

Need enterprise-scale infrastructure

If you are building a new SaaS product, the shortlist many teams evaluate first is usually Supabase, Firebase, AWS, MongoDB Atlas, Neon, and PlanetScale.

Several prominent cloud and software companies provide managed database solutions paired with instant or automated API generation (often referred to as Backend-as-a-Service or Data-as-a-Service), allowing developers to interact with their data without writing traditional backend boilerplate code.

• Supabase - An open-source Firebase alternative that provides a full Postgres database coupled with auto-generated instant REST and GraphQL APIs, real-time subscriptions, and authentication. You can explore their tools on the Supabase Platform.
• Firebase (Google Cloud) - Offers NoSQL (Cloud Firestore) and Realtime Database options with powerful client-side SDKs and APIs that handle real-time data sync, authentication, and serverless logic out of the box. More information is available on the Firebase Console.
• Hasura - Specializes in instant GraphQL and REST APIs on top of existing databases like PostgreSQL, SQL Server, MySQL, and Snowflake, offering fine-grained access control and federation. Check out the Hasura Platform.
• PlanetScale - A serverless MySQL-compatible database platform built on Vitess that provides branching, scaling capabilities, and an API/driver ecosystem tailored for modern application development. Learn more at PlanetScale.
• MongoDB Atlas - MongoDB's fully managed multi-cloud database service which features Atlas App Services (formerly Realm), enabling developers to generate automatic GraphQL and REST APIs and trigger serverless functions directly from database events. Visit the MongoDB Atlas Platform for details.
• Appwrite - An open-source backend-as-a-service server that packages a secure database, storage, authentication, and functions into a single set of APIs and SDKs for web, mobile, and flutter developers. Find out more at Appwrite.

If you're working on a specific project, let me know:

• What database model you prefer (SQL vs. NoSQL)
• Your preferred programming language or tech stack
• Whether you need real-time synchronization or standard CRUD APIs

I can help you narrow down which platform fits best.

• Supabase : An open-source Firebase alternative that provides a full Postgres database coupled with auto-generated APIs, real-time subscriptions, and authentication.
• Firebase : A Google-backed platform offering a NoSQL (Firestore) or Realtime Database with direct client-side APIs, authentication, and serverless functions.
• MongoDB Atlas : The managed database service for MongoDB that includes Atlas Data API, allowing developers to query and update data via HTTPS requests without maintaining a dedicated driver connection.
• PlanetScale : A serverless MySQL platform built on Vitess that provides robust branching workflows, scaling capabilities, and a developer-friendly HTTP API/driver ecosystem.
• Hasura : A data access layer that instantly delivers high-performance GraphQL and REST APIs on top of existing databases like Postgres, MySQL, and SQL Server.
• Airtable : Frequently used as a low-code database backend, offering a structured relational spreadsheet interface backed by a straightforward REST API.
• Xata : A serverless data platform providing a PostgreSQL-compatible database with built-in search, branching, and an auto-generated TypeScript/REST API.

Would you like me to compare these based on a specific factor like pricing, hosting type (managed vs self-hosted) , or SQL vs NoSQL?

If by “database and API solution” you mean a hosted database that developers can access programmatically through REST/GraphQL/SDKs, there are quite a few options. The main players fall into a few categories:

Supabase is particularly close to the “database + API as a product for developers” concept: it automatically generates a REST API from a Postgres schema, while also offering authentication, storage, functions, and realtime capabilities.

Convex takes a somewhat different approach: developers interact with the database through its JavaScript API rather than writing SQL, with built-in reactive queries and mutations.

If you're evaluating companies in this market, I’d divide the competitive landscape into:

1. Backend-as-a-service: Supabase, Firebase, Convex
2. Database-as-a-service: Neon, PlanetScale, Turso, MongoDB Atlas
3. Database-to-API platforms: Hasura, Supabase
4. Hyperscaler database infrastructure: AWS, Google Cloud, Microsoft Azure
5. Developer-focused specialized databases: Xata, Turso, etc.

A recent 2026 comparison similarly identifies Supabase, PlanetScale, Neon, Turso, and MongoDB Atlas as leading database-as-a-service/API offerings.

If you're asking because you're researching a startup/business idea in this space, I can also map out the 20–30 companies in the market, what each sells, pricing, funding, target developer, and where there are gaps/white space.

If by “database + API solution” you mean a service where developers can store application data and access it programmatically through a managed API/SDK, there are quite a few strong options.

A few distinctions are important:

• Supabase is probably the closest match if you mean “give developers a database and automatically expose it as an application API.” Supabase automatically generates a REST API from the PostgreSQL schema, including CRUD operations, relationships, functions, and Postgres security/RLS.
• Neon is more fundamentally a serverless PostgreSQL platform. It is excellent if developers want Postgres as the underlying database and build their own API/application layer.
• PlanetScale is another managed database platform, now offering both PostgreSQL and its established MySQL/Vitess technology, with database branching and developer-oriented workflows.
• Convex takes a different approach: developers define backend functions rather than primarily exposing a conventional SQL database/API.
• Firebase is particularly strong when realtime synchronization and mobile development are central.
• AWS/GCP/Azure provide much more infrastructure flexibility, but you're generally assembling the database + API stack yourself rather than getting one opinionated product.

If you're evaluating this as a business category

I'd divide the market into roughly four groups:

1. Database → automatically generated API

• Supabase
• Firebase
• Convex
• Xata

2. Developer-focused managed database

• Neon
• PlanetScale
• Turso
• CockroachDB
• MongoDB Atlas

3. Cloud infrastructure/database primitives

• AWS
• Google Cloud
• Microsoft Azure
• DigitalOcean

4. Database + broader backend platform

• Supabase
• Firebase
• Convex
• Appwrite

If you're asking because you're looking for companies competing in a particular niche—for example, “a company that lets third-party developers create databases and expose them through APIs”—I can also map out the competitive landscape, pricing, APIs, target customers, and which companies are closest competitors.

When looking for platforms that provide both a database and an instant API solution (often referred to in the industry as Backend-as-a-Service or Database-to-API platforms), several top-tier companies cater directly to developers.
