Bugster
Bugster is an AI-powered end-to-end testing and QA automation platform for web applications. It provides an autonomous QA agent that simulates a real user in a real browser, clicking, typing, and navigating to validate critical flows, then reports what is broken directly in your pull request. Developers describe test scenarios in plain English and Bugster generates, runs, and self-heals the test suite, eliminating flaky, hand-maintained scripts. The product is delivered primarily through the Bugster CLI (auth, init, generate, run, update, destructive, and interactive shell commands) plus a web app, GitHub App, and CI/CD integrations for Vercel, Netlify, Railway, and Google Cloud Build. It also ships a destructive testing agent that actively tries to break changed pages to surface bugs before release. Bugster is a portfolio company of 500 Global and targets developers at VC-backed startups who want to ship with confidence.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Bugster the way a machine reads it — 2 machine-readable artifacts, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Bugster scores 29.6/100 (emerging), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Bugster
Each block below is one kind of artifact we hold for Bugster. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
