   InsForge▲622

   We built InsForge because we wanted to use pure prompts to build a production-grade app faster. In practice, AI isn’t reliable enough when generating code or configuring backend pieces like schema, RLS, auth, or functions. Postgres MCP and Supabase MCP are a good starting point, but they felt more like API wrappers for agents than something designed to guide AI safely through backend tasks. So we built our own MCP server on top of Postgres and added a set of context-engineering tools to make prompt-driven workflows more predictable. It gradually turned into a Postgres-based BaaS. Key…

    BackendLab – Code-free web app builder▲65

    Hi all, I'm currently validating an idea for a new BaaS solution which will allow you to build and host a web app backend without writing a single line of code. The app is called BackendLab and the landing page is here: https://www.backendlab.app/ The idea is that it allows you to define your database models by specifying what fields to include and BackendLab automatically creates a CRUD API which you can start using straight away. We've just launched the public beta and are looking for early adopters (free of charge, just looking for some feedback on the tool) Looking forward…
