Coldtea

What is Coldtea?

Coldtea is a macOS development environment built for teams that already code with AI agents. It runs Claude Code, Codex, and other CLI agents side by side, then adds QA agents that test every pull request and monitoring agents that watch production. Problems found after release come back as tasks for the next agent.

Top Features:

• Parallel agents: run several coding agents at once, each in its own worktree.
• Agentic QA: plain English tests drive real browsers and simulators on every pull request.
• Production monitoring: agents read Sentry, PostHog, and Datadog data and file bugs.

Use Cases:

• Regression testing: catch broken checkout or signup flows before pull requests merge.
• Incident triage: turn production errors into ready tasks with plans for coding agents.
• Task handoff: keep plans and session logs on each Linear or Jira ticket.

Who Can Use Coldtea?

• Software engineers: ship agent-written code faster with tests and reviews in one place.
• Startup teams: get QA and monitoring coverage without hiring a testing team.
• Engineering leads: track what each agent planned, changed, and verified on tasks.

Pricing

• Terminal (free): every coding agent and agent team, with unlimited seats.
• Agentic testing (free): 2,000 credits each month, with web test runs at 10 credits.
• Extra credits (usage based): top up testing credits anytime, with no sales call needed.

Pros and Cons

Pros:

• Full loop: coding, testing, and production monitoring live in one app.
• Bring your agents: works with Claude Code, Codex, Gemini CLI, and OpenCode.
• Generous free tier: the terminal is free forever and testing includes monthly credits.

Cons:

• Mac only: versions for Windows and Linux are still waitlisted.
• Credit math: mobile test runs cost 100 credits, so free credits go quickly.
• Agent focused: teams without coding agents get much less value here.

FAQs:

1) Does it replace my coding agent?

No, it runs the agents you already use, such as Claude Code and Codex.

2) How does the QA agent test apps?

It clicks through your preview URL like a real user would.

3) Which monitoring tools does it connect to?

Sentry, Datadog, Grafana, New Relic, PostHog, and Vercel, with more on request.

4) Does my code leave my machine?

No, code stays local unless you turn on optional cloud runs for background agents.

5) Is Coldtea free?

Yes, the terminal is free forever, and testing and monitoring both have free tiers.
