The front of the fleet.

One console over your agent fleet. Bourdon remembers, Positif routes, Tremulant conducts — and you review what ships.

The trio

Three organs. One instrument.

Each part does one job and does it in the open where that matters. Run them together and the fleet becomes something you can trust with real work.

Memory
Bourdon

Shared memory across every agent you run. A new tool recognizes you and your work on its first turn — nothing re-explained, nothing lost between sessions.

Apache-2.0 interop · BUSL-1.1 engine
bourdon.ai →
Routing
Positif

The switchboard. Every dispatch is identified, checked against policy, loop-guarded, and written to an append-only ledger. It routes the fleet, reads nothing, proves everything.

MIT CLI · BSL 1.1 server

Autonomy
Tremulant

The conductor. Governed loops that let the fleet run itself — on a budget, inside protected paths, with a kill switch and a human gate. It conducts our own fleet today.

Proprietary · included in the Tremulant tier
It runs itself. It can't run away.
How it works

A fleet that runs itself — up to the moment that matters.

Tremulant polls Bourdon for work, dispatches it through Positif's checks, and the result comes back to a person. Autonomy for the labor; a human for the landing.

01 · tremulant
Wakes the fleet

Scheduled loops pick up open work from memory.

02 · positif
Checks the call

Identity, policy, loop-guard — then forward. Every hop audited.

03 · your agents
Do the work

In disposable workspaces. The real repo is never touched.

04 · bourdon
Remembers

Outcomes commit to shared memory for the next turn.

05 · you
Approve the diff

Review exactly what was proposed. It lands byte-for-byte, or not at all.

The stance

Open where it matters. Governed where it acts.

In the open: the parts you must be able to audit

The memory and the switchboard are source-available and self-hostable, free forever. You can read every line that touches your traffic.

  • Keys, agents, and the switchboard stay on your own network
  • Agent traffic never transits Prestant; we host the console, not your broker
  • One SQLite file. Leave any time, take everything.

Governed: the part allowed to act alone

Tremulant is the one layer that initiates work on its own — so it's the layer we keep tight, and the tier you pay for.

  • A reviewer is never the author — separation of duties, enforced
  • Per-loop budgets, protected paths, a disclosed hard cap
  • Nothing lands without a hash-bound approval
Pricing

Start free on your own metal. Pay when it runs itself.

Hosted tiers open with the founding cohort. Annual: two months free. Trials take a card; autonomy trials are capped so a runaway loop can't surprise anyone — including you.
