What you give up either way

  • Hosted ingestion, scaling, and uptime guarantees
  • Built-in integrations (Stripe, Shopify, LemonSqueezy) out of the box
  • Polished mobile apps, CLI, MCP server, and prebuilt AI agent integrations
  • Managed data retention, backups, and compliance packaging

An open-source project doing the core job proves a replacement is possible. It does not prove it matches DataFast, and it does not prove anyone has run it for a month. How we decide.
