FlareSolverr vs PostgREST
Which should you use? A side-by-side look at what each one does, who it suits, what it costs, how hard it is to set up, and where each falls short.
Open source · MIT
A local proxy server that opens a real browser to get past Cloudflare checks for your requests.
Open source · MIT
Turns an existing PostgreSQL database into a REST API with no hand-written server code.
The short answer
Choose FlareSolverr if you need…
- Developers whose scripts are blocked by Cloudflare challenges on pages they are allowed to access
- People running self-hosted tools that need to fetch Cloudflare-protected pages through a local REST endpoint
- Users who prefer running the service in Docker
Choose PostgREST if you need…
- Developers who already have a PostgreSQL database and want an HTTP API on top of it quickly
- Teams that want database rules and permissions to be the single source of truth for access control
- Projects that need API versioning through database schemas and views
- Backends that prefer declarative constraints in the database over application-level validation

What each one is
FlareSolverr
FlareSolverr is a proxy server that runs on your own machine and handles requests for pages protected by Cloudflare or DDoS-GUARD. When a request arrives, it launches a Chrome browser, loads the page, waits until the protection challenge is solved or times out, then returns the HTML and cookies. Other HTTP tools can then reuse those cookies.
PostgREST
PostgREST is a server that reads your existing PostgreSQL database and serves a RESTful HTTP API from it. Developers use it to avoid writing and maintaining custom API code for common create, read, update, and delete operations. Authentication uses JSON Web Tokens, and authorization relies on the database's own roles.
Best for
FlareSolverr
- Developers whose scripts are blocked by Cloudflare challenges on pages they are allowed to access
- People running self-hosted tools that need to fetch Cloudflare-protected pages through a local REST endpoint
- Users who prefer running the service in Docker
PostgREST
- Developers who already have a PostgreSQL database and want an HTTP API on top of it quickly
- Teams that want database rules and permissions to be the single source of truth for access control
- Projects that need API versioning through database schemas and views
- Backends that prefer declarative constraints in the database over application-level validation
Strengths
FlareSolverr
- Runs as a simple REST API that works from curl, Python, or PowerShell
- Reuses browser sessions so you do not have to solve challenges on every request
- Available as a Docker image, precompiled binary, or from source under the MIT license
PostgREST
- Uses the database as the source of truth for authorization and data validation
- Built in Haskell with pooled connections and binary protocol access, which the README says gives good response times
- Generates OpenAPI documentation automatically from the database structure
Not ideal for
FlareSolverr
- Anyone planning to expose it to the internet, since the README warns it can be abused
- Machines with little RAM, because each request launches a new browser and browsers use a lot of memory
- Users who need to run it on non-x64 hardware outside Docker, since precompiled binaries and source installs are x64 only
PostgREST
- Projects not using PostgreSQL, since the README describes it only for PostgreSQL databases
- Teams that need a lot of custom application logic inside the API layer, which the README's model of delegating work to the database does not suit well
- Non-developers, because setup requires database roles, JWT configuration, and familiarity with SQL
Trade-offs
FlareSolverr
- Browsers consume significant memory, so concurrent requests need enough RAM
- Works only for sites you are permitted to access; it is not a general guarantee against blocking
- Setup has platform-specific caveats such as Chromium not working on Windows for source installs
PostgREST
- Performance claims in the README come from a single Heroku free-tier benchmark and should be verified for your own workload
- Its security and data-integrity model depends on correctly designing database roles and constraints, which takes SQL expertise
- The README is truncated here, so details of configuration and limitations are not covered in this entry
Getting started
FlareSolverr
Start the container with the Docker CLI
docker run -d --name=flaresolverr -p 127.0.0.1:8191:8191 -e LOG_LEVEL=info --restart unless-stopped ghcr.io/flaresolverr/flaresolverr:latestFrequently asked questions
