Apidog vs Supabase

Apidog is an all-in-one API development platform that puts design, debugging, testing, mocking and documentation in one tool, so a team works from a single OpenAPI-based source of truth instead of passing specs between Swagger, Postman and a docs site. It runs in the browser and as desktop apps for macOS, Windows and Linux, and it markets itself directly as a cheaper Postman alternative.

Designers build endpoints and JSON Schemas in a visual editor; developers send requests over HTTP, GraphQL, gRPC, WebSocket, SOAP and SSE with Postman-compatible scripts; QA builds visual test scenarios, scheduled runs and performance tests; schema-driven mocks need no code; and interactive docs publish with custom domains. Sprint branches, Git connection, a CLI for CI/CD and self-hosted runners round it out. The free plan covers up to four users; Basic, Professional and Enterprise are billed per member, and documentation readers are free.

It fits teams that want to replace Postman plus a separate docs and mock tool. Stoplight and Redocly are stronger for pure design governance, ReadMe and Mintlify produce more polished public developer portals, and Postman has the larger ecosystem. Apidog's mock and docs features are less mature for large public API programs.

Recent releases focus on AI: an MCP server that feeds API specs to Cursor and other AI editors, an MCP client and AI agent debugger, AI test case generation and schema compliance checks. Apidog also offers an EU data region and an on-premises edition. Import a Postman collection during the 14-day trial to compare.

Supabase is an open-source backend platform built on PostgreSQL, founded in 2020 by Paul Copplestone and Ant Wilson. It started as an open-source alternative to Firebase and has become one of the most popular backends for web, mobile and AI applications, especially among TypeScript, Next.js and Flutter developers.

Every project is a full Postgres database with extensions such as pgvector, plus auto-generated REST and GraphQL APIs, so the frontend can query data directly while row-level security policies protect it. Authentication supports email, magic links, OAuth providers, phone and multi-factor login. Storage serves files through a CDN with image transformations, Edge Functions run server-side TypeScript on Deno, and Realtime pushes database changes and broadcast messages to clients. Branching creates isolated databases for previews. A free plan covers two projects with limits and pauses inactive projects, Pro costs a fixed monthly fee with usage-based extras for compute and bandwidth, and Team and Enterprise add compliance, SSO and support.

Supabase suits startups, indie developers and product teams that want a managed backend without giving up SQL or the option to self-host. Costs rise with compute add-ons and egress at scale, and complex multi-region write needs are outside its sweet spot. Firebase remains strong for real-time mobile apps on Google Cloud, Neon focuses on serverless Postgres alone, and Appwrite and PocketBase are other open-source backends. AI app builders such as Lovable and Bolt use Supabase as their default backend.
