Ship at agent speed.
Break nothing.

Coldtea runs the full SDLC. Agents test every pull request on a real device, watch production, and file what breaks before your users find it.

Every other agentic development environment stops at the pull request.

Coldtea runs the full SDLC.

Let's walk through your first day in Coldtea

Say you have agents writing code all day.

9:12 AM

The task shows up

Import your board from Linear, Jira or GitHub Issues in one click. MAT-214 is already here, with its description, and it syncs both ways.

Coldtea Tasks board · MAT-214 in focus
9:40 AM

Your agents pick it up

Start it in the terminal. Run several agents at once on the same task. They share context, so they can work in parallel and build on each other's work.

11:05 AM

The work explains itself

Every agent session leaves a plan and a log on the task. Come back in a week, or hand it to someone else. The thinking is still there.

1:20 PM

You open a PR

Nothing leaves your machine until you say so. When it does, the pull request closes the task it came from, so everything after this points back to one change.

PR #7 · closes MAT-214, from mat-214-promo-codes
1:24 PM

Every pull request gets regression tested

QA agents open the preview URL for your pull request and click through the product like real users. All we need to test your app is a URL, we'll handle authentication, bot detection, agent orchestration and more.

Applying promo code MATCHA10 takes ten percent off the total.Tests in plain English. Run on web, desktop, iOS and Android.
A QA run against the preview deployment, step by step
2:58 PM

You ship

Merge. Deploy. Then the same tests run again, this time on production.

Merged #482 + production run, green
3:00 PM

Production is watched

Connect Sentry, PostHog, your logs, your feedback inbox. Monitoring agents read them all day, the way an on-call engineer would.

9:06 PM

What broke comes back as work

A monitoring agent saw that a wrong address could bypass client and server validation. It repeated the bug and filed MAT-209 on this morning's delivery board, ready for the next agent to pick up. No user had to report it.

Morning brief and delivery board

That is how you ship fast without breaking things

You focus on your product. We bring the infrastructure for cloud runtime, agentic testing and production monitoring.

Loved by developers

Most AI-generated code is slop that goes nowhere. Anyone can write code, but building software that works is still hard and requires much more than the ability to prompt a model. I like what these guys just released. Keep your terminal and your coding agent, and use Coldtea to Show more

Tried Coldtea’s QA agent on one of my own side projects last night. Gave it a user flow, then watched it actually drive the browser and click through the live app instead of just scanning the code. It found an edge case I’d completely overlooked. That’s the part that got me.

And everything you already expect

The loop is what makes Coldtea different. Here is the rest, so you are not left guessing.

Terminal

  • Your shell, settings and dotfiles, set up for you
  • Claude Code, Codex, Gemini CLI, OpenCode and more
  • Agent teams that plan, build and review together
  • A git worktree per task, so runs never collide
  • MCP servers and your existing agent config

Cloud

  • Background agents that run tasks off your laptop
  • Many tasks in parallel, followed from one place
  • Off by default. Your code stays local until you turn it on

Tasks

  • Two-way sync with Linear, Jira and GitHub Issues
  • Implementation plans and session logs on every task
  • Board, backlog and workflow states built in

Built in

  • An editor built in, so a diff never sends you elsewhere
  • In-app browser you and your agents can both drive
  • Annotate any pane or page and send it straight to an agent
  • Monitoring across Sentry, Datadog, Grafana, New Relic, PostHog, Vercel

You keep everything you already use

Your editor stays your editor

Your shell is set up for you and your settings come across. Day one looks like every other day.

Your code stays on your machine

Cloud runs are there when you want them, and off until you do.

Your agents stay your agents

Coldtea is not another coding agent. It runs the ones you picked.

Free as in freedom

Terminal

Free forever

Every agent, every agent team, no seat count and no trial clock.

FAQ

Questions we get a lot

Anything else, email hello@coldtea.ai

Coldtea is an IDE, not a dashboard. It runs on your machine, right next to your repo, using the shell, agents and settings you already have. It is a new kind of agentic development environment: the terminal you work in every day, with testing and production monitoring built around it.
