Heeler

Heeler is the Agentic Development Security Platform — machine-speed security for AI-written code. As coding agents (Claude Code, Cursor, GitHub Copilot) and AI attackers reshape the software development lifecycle, Heeler prevents vulnerabilities during code generation, autonomously fixes dependency and code issues with CI-validated merge-ready pull requests, and continuously audits open source (SCA), code security (SAST), secrets, and agent-skill threats across the AI SDLC. It embeds security policy into coding agents through MCP servers and agent skills, deploys without build modification ("live in a day"), and is SOC 2 Type II certified. Heeler is backed by Norwest Venture Partners.

Heeler is profiled on the APIs.io network. Tagged areas include Company, Security, Application Security, DevSecOps, and Artificial Intelligence.

Heeler’s developer surface includes pricing, signup flow, engineering blog, support, CLI, and 15 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
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.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
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/heeler: open an issue to ask a question, or submit a pull request to add artifacts.

Standards implemented 2

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

Agent Skills
tagged — the provider's own APIs.json carries the standard as a tag; implementation not verified
