A2Apex is where AI agents earn trust.
Point it at any agent built on Google's A2A protocol and it runs 50+ automated compliance tests across 5 categories:
Agents earn a 0-100 trust score with Gold, Silver, or Bronze certification badges they can embed in READMEs, docs, or websites.
Every tested agent gets a public profile page in the Agent Directory with trust scores, capabilities, test history, and a live "Try This Agent" chat.
Built on Google's A2A Protocol โ the open standard for agent-to-agent communication with 22K+ GitHub stars.
Free tier: 5 tests/month. Pro: $29/mo unlimited.

A2Apex.io's answer:
A2Apex is the only platform that combines A2A protocol testing, certification badges, and an agent directory. It's not just a testing tool โ it's a trust layer where agents build reputation through verified compliance scores.
A2Apex.io's answer:
Nobody else focuses on Google's A2A protocol specifically. Competitors test APIs generically โ A2Apex understands A2A semantics: agent cards, task lifecycles, JSON-RPC messaging, SSE streaming. Plus, tested agents get listed in our public directory with embeddable trust badges.
A2Apex.io's answer:
Developers and teams building AI agents that need to communicate with other agents using Google's A2A protocol. Also companies evaluating third-party agents who want verified compliance before integrating.
A2Apex.io's answer:
Built by a dragline operator in Wyoming who saw Google's A2A protocol gaining traction (22K+ GitHub stars) with zero developer tooling around it. Classic picks-and-shovels play โ Google markets the standard, A2Apex builds what developers need to use it.
A2Apex.io's answer:
Python, FastAPI, vanilla JavaScript, SQLite, Uvicorn, Stripe, Vercel, Cloudflare

This is pretty cool - the Jira/Linear integration could save a ton of manual work. How do you handle test data setup and teardown? That's usually where these workflows get messy. For alternatives in this space, there's qawolf (https://qawolf.com) for similar automated testing workflows, or I'm actually building bug0 (https://bug0.com) which also does AI-powered test automation, still in beta.

Platforms like Browserstack or SauceLabs offer virtual instances of real devices and browsers for manual and end-to-end testing. Caveat: subscriptions cost money and are on a per-seat basis. - Source: dev.to / about 2 years ago
If you go to browserstack.com (a website to test other websites) you can probably to the chatgpt url and sign up there. Source: over 3 years ago
For testing on Mac or iOS, use browserstack.com, you'll spend considerably less using that than you would buying the actual hardware. Source: over 3 years ago
I've seen subscription services such as browserstack.com and lambdatest.com but I believe they cost to get the full range of mac browsers and devices. Source: over 3 years ago
