You write code that defines agents and their flow, in-process, one orchestrator spawning sub-agents. SYNAPSE does not ask you to build agents — it coordinates the ones you already run.
The coordination bus for parallel AI agents
A local-first, model-agnostic hub so several AI coding agents from any vendor work in parallel on one repository without stepping on each other. Work claims, a shared plan, presence, direct messaging, and a durable event log. Runs on your machine; no cloud, one dependency.
$ pip install synapse-channel
Not a framework. Not git worktrees.
Agent frameworks
Git worktrees
Isolation, not coordination
Worktrees give each agent its own checkout and defer conflicts to merge time. That separates agents; it does not let them coordinate in real time. SYNAPSE is the coordination layer — they can share, claim, and talk.
SYNAPSE CHANNEL
The bus beneath them
A standalone, local-first coordination bus any terminal agent speaks: advisory file-scope claims, a shared blackboard, presence, peer messaging, and an event log that survives restarts. The "agent service bus" most people only build ad-hoc.
What the hub gives you
Work claims with file scope
An agent leases a task and declares the files it will touch; the hub refuses an overlapping claim, so two agents never edit the same file. Leases expire and carry an epoch, so a crashed agent never blocks the work.
A shared plan + handoffs
A dual-ledger blackboard tracks tasks and progress with dependencies; a held task can be handed off atomically; a stall supervisor re-offers stuck work — all without a model in the loop.
Presence + direct messaging
See who is live, address one agent, a whole project group, or everyone. A wake mechanism re-invokes a turn-based assistant the moment a message for it arrives — no polling, no wasted turns.
Durable event log
Every claim, release, task, and checkpoint is recorded in an append-only SQLite log and replayed on restart, so a hub restart resumes live leases instead of losing them. It doubles as a cross-agent audit and provenance trail.
It runs the fleet that builds it
SYNAPSE coordinates the team that develops SYNAPSE. Several AI agents across a dozen research projects coordinate through one hub every day — directives, work claims, and recovery all flowing over the channel.
Because we live in it, the friction we hit becomes the product. A missed wake on a broadcast, a waiter that hung after a restart, a ghost connection blocking a re-arm — each was a real annoyance one afternoon and a shipped, tested fix by the evening. The changelog reads like a logbook of a tool sharpening itself. That is the model your licence funds: a coordination substrate that improves because its authors depend on it.
Free to start. Pay what it is worth.
Open-source under AGPL-3.0 — free for research, personal, and open-source use. A commercial licence (pay-what-you-want, from CHF 9.99) removes the copyleft for closed-source and SaaS, and funds the research, electricity, and tokens behind it.
