Db2rest
Open-source instant REST API for any SQL database — no boilerplate.
Db2Rest is the right call when you need a fast, secure REST API over multiple relational databases without ORM overhead. Its SQLite support in v1.6.5 widens its appeal, but the absence of a managed cloud and limited auth options may give enterprises pause. If you're PostgreSQL-only, PostgREST or Supabase offer more polish; for multi-database flexibility, Db2Rest is a solid open-source bet.

Skip Db2Rest if you need a fully managed database API service with built-in user management, or if you require NoSQL support (MongoDB is not yet available).
Self-hosted infrastructure: you must cover the cost of servers, storage, and bandwidth; no managed option exists, so cloud bills come out of your pocket.
Db2Rest is free and open-source, so the only costs are your infrastructure. This makes it an excellent fit for startups and small teams that want to avoid per-seat or per-API-call fees. Compared to managed services like Supabase (which has a free tier but charges for usage) or PostgREST (free but limited to PostgreSQL), Db2Rest offers cost savings for teams needing multi-database support.
In short
Db2rest — Open-source instant REST API for any SQL database — no boilerplate. Best for Backend developers building REST APIs quickly without boilerplate, Frontend teams needing instant backend data endpoints, DevOps / platform engineers managing database access. Free to use.

About Db2rest
Db2Rest is an open-source tool that turns relational databases into secure REST APIs in minutes, eliminating the need to write boilerplate database access code. It supports PostgreSQL, MySQL, MariaDB, CockroachDB, and SQLite (added in v1.6.5), making it a versatile choice for teams working across multiple database systems. The tool is designed for backend developers, frontend teams, and DevOps engineers who want to accelerate application development without sacrificing security or performance. Db2Rest addresses common database access pitfalls like connection leaks, transactional inconsistency, and SQL injection by providing a no-code data access layer. It uses MyBatis Dynamic SQL to achieve single round-trip queries, database query caching, and batching, avoiding the overhead of ORMs. With Db2Rest, you can expose tables, views, stored procedures, and custom SQL queries as REST endpoints, complete with filtering, sorting, pagination, and implicit multi-table joins. Key capabilities include CRUD endpoints, custom SQL execution, stored procedure calls, bulk inserts in JSON and CSV formats, and automatic TSID key generation. The tool also supports SSL certificate authentication for PostgreSQL and CockroachDB, cross-schema queries, and API authentication via Unkey. You can run Db2Rest on-premise, in Docker, Kubernetes, or any cloud, and its lightweight footprint (reduced Docker image and executable jar size) makes it easy to deploy. Compared to PostgREST or Supabase, Db2Rest offers broader database coverage—including SQLite, CockroachDB, and MariaDB—and a lighter footprint with no code generation. While it lacks a managed cloud offering and a full admin UI, it provides a fast, secure REST layer for teams needing flexibility across multiple relational databases.
Behind the Verdict
Db2Rest delivers on its promise of turning SQL databases into REST endpoints with minimal setup. The recent addition of SQLite (v1.6.5) makes it a genuinely multi-database tool, and its lightweight footprint—no code generation, no ORM—means you can have an API running in about 10 minutes. It shines for backend teams that want to skip boilerplate data-access code and for frontend developers who need a quick backend for prototyping. The integration with Unkey for API authentication is a plus for securing endpoints without building your own auth. However, Db2Rest is not a full platform. There’s no managed cloud, so you handle deployment, scaling, and monitoring. It lacks a built-in admin UI, so non-technical users will need other tools (like a database GUI) to manage data. Authentication is limited to Unkey; you won’t find built-in user management or role-based access control. Also, MongoDB support is listed as 'coming soon' but not yet available, so if you need NoSQL, you’re out of luck. Where it fits: startups modernizing legacy MySQL databases, GenAI developers who need a quick function-calling endpoint to query data, and teams that value open-source flexibility across multiple SQL backends. Where it doesn’t fit: enterprises that require SLAs, managed security, or a user-friendly admin console, and anyone needing real-time data streaming. If you’re deeply invested in the PostgreSQL ecosystem, PostgREST or Supabase offer richer tooling; if you need multi-database support without vendor lock-in, Db2Rest is a strong choice.

Real-world workflow fit
Concrete scenarios for the personas Db2rest actually fits — and what changes day-one when you adopt it.
You need to expose a PostgreSQL table as a REST endpoint for a new mobile app backend. Instead of writing a full CRUD controller, you deploy Db2Rest via Docker and configure the connection; in about 15 minutes you have a working endpoint with filtering, sorting, and pagination.
Outcome: Your team saves days of boilerplate coding and can focus on business logic.
You're building a chatbot that needs to query a MySQL database for order information. You use Db2Rest to create a REST endpoint and then integrate it as a function call for your AI model, so the model can pull live data securely.
Outcome: The chatbot can now answer questions with real, up-to-date data without you writing custom database code.
Your team manages a mix of legacy SQLite and MariaDB databases and wants to modernize access. You deploy Db2Rest on Kubernetes, configure cross-schema queries, and enable Unkey authentication, providing a single REST layer for both databases.
Outcome: Internal teams can integrate with legacy data quickly, and you centralize access control.
Use Cases
- Create a REST API endpoint from any PostgreSQL table in under 10 minutes.
- Expose legacy MySQL database data securely to modern frontend applications.
- Integrate GenAI tool calls with a database via REST for function calling.
- Generate TSID-based primary keys automatically when inserting new records.
- Invoke stored procedures and custom SQL queries through a standardized REST interface.
Limitations
- Db2Rest currently supports PostgreSQL, MySQL, MariaDB, CockroachDB, and SQLite as of the latest release.
- MongoDB support was planned but is not yet available.
- It is a self-hosted tool, so you must manage deployment and scaling; while it provides API authentication via Unkey, it has no built-in user management.
- Some features may be undocumented, as noted in the official blog.

Where the pricing makes sense
The company stage and team size where Db2rest's pricing actually pencils out — and where peers do it cheaper.
Db2Rest is free and open-source, so the only costs are your infrastructure. This makes it an excellent fit for startups and small teams that want to avoid per-seat or per-API-call fees. Compared to managed services like Supabase (which has a free tier but charges for usage) or PostgREST (free but limited to PostgreSQL), Db2Rest offers cost savings for teams needing multi-database support.
Setup time & first value
How long it actually takes to get something useful out of Db2rest — broken out by persona, not the marketing-page minute.
For a PostgreSQL or MySQL table, you can go from zero to a working REST endpoint in about 10 minutes using the Docker image. If you're running on Kubernetes, allow 30-45 minutes for initial configuration. SQLite setup is even faster—just point Db2Rest to your file and you're live.
Switching to or from Db2rest
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From PostgREST: Replace your PostgREST config with Db2Rest's YAML/JSON setup; adjust your queries to Db2Rest's endpoint syntax.
- →From Supabase: Export your PostgreSQL schema and re-create it in your own database; then configure Db2Rest with the same connection details.
- →From writing custom Express/Spring endpoints: Retire your boilerplate code and route requests to Db2Rest; you'll need to update your frontend URL base.
- ↗To PostgREST: If you standardize on PostgreSQL, migrate your data and adjust endpoint calls to PostgREST's query format.
- ↗To Supabase: Use Supabase's import tools to move your schema and data; rewrite any custom SQL functions to PostgREST conventions.
- ↗To a managed service (like AWS RDS + API Gateway): Rebuild your REST layer using managed components; more work but adds SLAs and built-in auth.
