This topic covers the platforms and services you plug into a build: tracing and evals, vector and data layers, agent runtimes, payments, auth, and the hosts that ship your work. They're the supporting cast that turns a clever prototype into something you can run and trust in production.
Some are open source and self-hostable; others are commercial SaaS with free tiers. The right pick depends on where the gap in your stack is — instrumentation, retrieval, deployment — and how much you want to operate yourself. Open each entry for pricing, hosting options, and how it fits alongside the tools you already run. Shipped indie products and vibe-coded builds live under Apps instead.
Standalone AI platforms and services that aren't an editor, plugin, MCP server, or a shipped indie app — hosting, auth, payments, observability, evals, data and search, orchestration, inference, and deployment utilities you integrate into a stack.
Platforms & Services are infrastructure you plug into your setup. Apps are finished products builders ship — vibe-coded demos, indie SaaS, and personal tools, including launches from communities like Builders Work Club.
Plugins extend a tool you already run from inside it; platforms and services stand on their own and you connect to them. A plugin lives in your editor; an entry here is its own platform or service.
Both. Some are open source and self-hostable, others are commercial SaaS, and many offer a free tier. Open an entry for licensing, hosting options, and pricing.
