Powered by a competition-winning agent harness

The agentic coding platform for your most difficult projects.

Swarmli turns one conversation into a swarm of agents. They grill your idea, write the spec, build in parallel and prove that every change works — before it ever reaches your review.

Agent Meetings

Meetings where the agents did the homework.

Swarmli books an Agent Meeting into your calendar and walks you through the agenda. It grills every ticket with questions it has already answered for you, writes the spec, cuts the work into tickets — and saves nothing until you say so.

Usage-based billing

Customers on the Growth plan want to pay for what they track, not per seat. Finance needs invoices that show it.

Grill this Ticket to write its Spec, or skip it.

  • Booked into your free time

    Swarmli reads your calendar and plans the meeting where you have room.

  • Answers already recommended

    Every question comes with the option the swarm would pick, and why.

  • A Spec you can build from

    Goal, rules and acceptance criteria — written while you decide.

  • Tickets that know their order

    Sub-Tickets with what blocks what, ready for agents the moment you save.

The swarm

A swarm, not a single chat.

Other tools give you one agent in one chat window. Swarmli runs as many as the work needs — each on its own branch, watched by its own Observer, conducted by a hub that never sleeps.

mainACM-53 · Claude CodeACM-61 · CodexACM-47 · Claude CodeACM-41 · Codex
  • One worktree per ticket

    Every agent works on its own branch, in its own checkout. Nothing collides, everything merges.

  • Observers that correct

    A second agent watches the first and sends corrections the moment it drifts from the Spec.

  • Handoffs, mid-flight

    Claude Code, Codex, Cursor — hand a Session to another agent without losing a line of context.

  • A fleet that heals itself

    Stalled agents get a nudge, then a restart. Only what truly needs you reaches you.

The harness

A competition-winning agent harness.

Under every agent runs a harness built to win coding contests against the clock. It races several solvers at once, judges every answer before you see it, and repairs in the same breath. Here it is next to your usual vibe-coding flow.

Review walk

Merge requests that explain themselves.

Every change arrives as a guided walk: what it is, the proof that it works, and the diff cut into steps that make sense. Reviewing a day of agent work takes minutes, not an afternoon.

  • In the order you should read it

    The agent that wrote the change plans your review: overview, proof, then the code in slices.

  • Evidence, not promises

    Recordings of the feature working, test logs, and every acceptance criterion ticked against them.

  • Reviewed before it reaches you

    Code review, security review and verification ran first. You decide; you don’t dig.

What this change is

Growth workspaces now pay per tracked event. Usage is counted per workspace and day, priced in four tiers, and shown as lines on the invoice. A failed charge retries three times over seven days before ingest pauses.

Fully autonomous runs

You sleep. The swarm ships.

Hand Swarmli a goal and a budget before you leave. It plans, grills, builds, reviews, verifies and merges through the night — measuring against your targets, and saving the one question it couldn’t answer for your morning.

Beyond the code

Everything around the code, too.

From the first customer call to the incident at three in the morning, Swarmli covers the whole life of a difficult project — not just the part where code gets typed.

Concept workshops

Join the customer call. Leave with a clickable prototype.

Swarmli listens, asks the questions you forgot, maps the systems involved and builds the prototype while you talk.

System map

Every system, every gap.

Unknowns get a best-guess assumption at once, so work never waits for an answer.

Voice

Talk to your swarm.

On a walk or on the drive in: steer every agent with your voice.

“Put ACM-61 on two agents and ship it by noon.”

Self-healing production

Incidents fix themselves.

An alert becomes a ticket, a fix, a verified merge — before anyone is awake.

Targets

Performance that holds.

Set a bar once. Every merge proves it got no worse.

Swarm memory

It learns how your team builds.

Conventions, decisions and taste — remembered across every project and every agent.
