Create GitHub profile and repository cards for READMEs, link previews and social posts.

Flaky CI triage, PR flow and DORA metrics for GitHub repos, from your own Actions history

Deterministic digital jobs with independently verified deliverables. 32 data and code capabilities (CSV validation, JSON schema checks, GTIN checks, Python module generation) executed in a confined sandbox; every deliverable is independently re-verified before delivery. MCP over Streamable HTTP, plus A2A and OpenAPI. Capability discovery accepts tasks in English, Arabic, Spanish, French, German, Portuguese, Chinese and Japanese; discovery only, deliverables are produced in English.

Local MCP server that lets your coding agent run simulators of real APIs (Stripe, GitHub, Slack) on your machine: start, seed, move the clock, inspect, diff, save tests.

Ranked fixes from the real users of your site (rage clicks, dead buttons, JS errors, slow pages) for your coding agent over MCP. Hosted, free plan.
