AI Cost Gate is a local-first cost black box for AI agents. • OpenAI-compatible request path • Attribute spend by project / agent / model • Budgets that can return HTTP 429 so agents stop when spend trips • Metadata-oriented — designed so prompt bodies stay on your side • Pro = one-time source license, self-host on SQLite or Postgres Free companion tools (pricing, burn estimator, prompt cost, MCP templates, checklist): https://tools.aicostgate.com
Hey Product Hunt 👋
AI Cost Gate started from a boring failure mode: coding agents that keep calling providers at 3am while dashboards only explain the invoice tomorrow.
What you get with Pro ($29 one-time):
- private GitHub source access
- self-host forever
- attribution + budget auto-stop on the request path

Happy to answer deploy / SQLite vs Postgres / “will this work in front of Cursor?” questions all day.
