Crash-proof LLM pipelines. Resumes from failure without a database.
About
DagPipe makes LLM pipelines crash-proof by saving each completed node's output to a plain JSON file. When a pipeline fails, re-running it skips finished nodes and resumes from exactly where it stopped. No database, no broker, just files.
Built for developers who are tired of losing pipeline progress to timeouts, rate limits, and bad model responses. Especially useful when running multi-step workflows on free tier APIs where every failed node costs real quota.
Ships with smart model routing by task complexity, Pydantic schema validation with auto-retry on malformed output, dead letter queue for failed nodes, context isolation so nodes only see their declared dependencies, and an MCP server for generating pipelines directly from Claude Desktop, Cursor, or Windsurf.
