IndieStack

Dependency guardrail for AI coding agents. Validates packages before installation, catches hallucinations and typosquats, and provides compatibility intelligence across 6,500+ developer tools.

10,000+ PyPI installs | 110,000+ unique visitors | 23 MCP tools

Terminal

claude mcp add indiestack -- uvx --from indiestack indiestack-mcp

Then ask your agent:

"Validate this package before installing"
"Find an auth solution for my Next.js app"
"Check compatibility between these two tools"

What it does

Before your AI installs a dependency or writes boilerplate — IndieStack validates it exists, checks for typosquats, and searches 6,500+ curated developer tools with real compatibility data from 4,500+ repos. You get install commands, health scores, and what tools actually work together in production.

"Indie" is the curation filter: independent developers and small teams. Focused, lean, maintained, honest pricing.

Tech stack

Backend: Python 3 / FastAPI / SQLite (FTS5 full-text search, WAL mode)
