Coding agents
that grow from
junior to senior.
Launch state-of-the-art coding agents asynchronously in the cloud, grounded in a persistent memory of your codebase — routes, call graph, and team conventions, injected exactly when they're needed. Every run makes the next one sharper.
2,000+ installs of the Kurtel CLI and counting.
Built on the most capable coding models and the strongest isolation primitives:
Net cost per task, caching included.
7.2 → 4.2 — less blind exploration.
Fan out across repos — no local machine.
Routes, imports & call graph, extracted locally.
Launch agents in the cloud, come back to shipped code.
Kurtel runs SOTA coding agents asynchronously in isolated cloud sandboxes. Fire off a task, close your laptop, review the result.
One command to launch
From CLI, dashboard, or API. Point an agent at a repo and a task — it provisions its own environment and gets to work.
Reviewable results
Agents return clean diffs and pull requests with the reasoning trail attached — review feels like reviewing a teammate.
Parallel runs
Fan out dozens of agents across repos at once, each in its own sandbox.
Codex + Claude Code
Built on the strongest coding models available today.
Stateless sandboxes
Fresh, isolated environments provisioned per run.
API-first
Drive everything from the CLI, SDK, and webhooks.
A living map of your codebase, injected per task.
Kurtel extracts your routes, import graph, and call graph locally — then injects only what each task needs. Deterministic, zero-token, and aware of what a change would break.
Deterministic & free
AST extraction runs locally — same input, same map, zero tokens.
Cross-lingual
Prompt in any language; aligned vectors resolve it to the right code.
Blast radius
Reverse call-graph shows exactly what a change breaks, before it ships.
Conventions learned from every merged PR.
Kurtel reads how your team actually ships — merges, review comments, reverts — and distills it into living patterns. Each one earns or loses fitness over time, so the memory sharpens instead of drifting.
Stripe payments must use embedded checkout — never a redirect.
New API routes return a typed Result<T>, never raw JSON.
Background work goes through the queue in jobs/, not inline in handlers.
A merged PR or review comment reveals a convention.
Later PRs that follow it raise its fitness.
A PR that breaks it lowers fitness — dying patterns go quiet.
Only what's relevant, ever injected
A pattern only reaches the agent when the task touches its zone or triggers. Nothing relevant? Nothing injected — no context tax for freeloading lines.
Stop hand-maintaining a skills system.
Teams write rulebooks — AGENTS.md, .cursor/rules, skill files — then spend forever keeping them current. Kurtel grows and prunes that knowledge for you, from how you actually ship.
A skills system you babysit
- Write the rulebook by hand — AGENTS.md, cursor rules, skill docs.
- Update it every time the codebase shifts, or it quietly goes stale.
- Outdated rules mislead the agent; no one knows which still apply.
- The whole rulebook gets dumped into context every prompt — noisy and costly.
Hours every week · knowledge that rots
Memory that maintains itself
- Conventions learned automatically from your commits, merges and reviews.
- Fitness decays what's wrong — dying rules go quiet on their own.
- Only the rules relevant to the task get injected. Nothing else.
- Adapts as you ship. You never open a rulebook again.
Zero upkeep · sharpens as you ship
Your code stays yours. Always.
Agents work on your code, but it never leaves the isolated sandbox it runs in. We built Kurtel so we can't see what we're not supposed to.
Code enters, work happens, results come back — the boundary is never crossed by us.
Isolated sandboxes
Every run executes in its own hardened, network-isolated, SOC 2-compliant cloud sandbox. No shared state between customers.
Zero code access
Your source stays inside the sandbox. Kurtel operators never read, copy, or retain your code.
Ephemeral by design
Sandboxes are torn down after each run. Nothing lingers once the work is shipped back.
Scoped credentials
Agents get the minimum access a task needs, revoked the moment the run ends.
We're looking for design partners.
Kurtel is early. We're partnering with a handful of teams who want self-improving coding agents and are willing to shape them with us.
