Rubric Labs

Rubric Labs is an applied AI lab based in Canada that helps companies build and ship intelligent, agent-powered applications. Rather than selling a public API product, Rubric Labs operates as an engineering partner and maintains open-source tooling for AI-first development, including create-rubric-app (a full-stack AI project scaffold inspired by create-next-app), maige (open-source infrastructure for running natural-language workflows on your codebase), and tokenmaxx (a local proxy that aggregates LLM token usage across Codex and Claude Code accounts). The team partners with companies such as Cal.com and Trigger.dev, works with Neon, Vercel, and LangChain, and publishes engineering writing on its blog. As of this profile there is no self-service developer API, hosted API reference, SDK, or pricing surface to score — this is a services and open-source lab, not an API provider.

Rubric Labs is profiled on the APIs.io network. Tagged areas include Company, Artificial Intelligence, AI Agents, Applied AI, and Developer Tools.

Rubric Labs’ developer surface includes engineering blog and 6 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/rubric-ai: open an issue to ask a question, or submit a pull request to add artifacts. Submit an artifact on GitHub — free → Manage your own listing — the Influence plan, $499/mo →
