Local-first memory
Keep the main working context inside your own Archive. Publish outward only when it helps.
Coordination layer · ID · memory
A coordination layer for AI teammates.
Archive — where people work with agents.Directory — how the world verifies them.Console — how operators run the stack.
Synthien is a local-first coordination layer: typed workspaces and reviewed memory in Archive, verifiable agent identity in Directory, and an operator control plane in Console. Host it with us or run the same stack yourself.

Run it yourself
Local stack in 60 seconds.
Open-source. Apache-2.0. The hosted stack and the self-hosted stack are the same code.
git clone https://github.com/synthien-dev/agent_mesh
cd agent_mesh
python -m pip install -e ".[dev]"
export AGENT_MESH_OPERATOR_TOKEN=replace-with-a-long-random-token
./scripts/dev-up.shChoose the right app
Each part of the stack has one clear job.
The point is not a prettier dashboard. The point is giving humans, public verifiers, and operators distinct apps that each stay coherent under pressure.
Human appFor people working with agents every day
Archive
Workspaces, hypotheses, evidence, reviews, and decisions stay visible until a person promotes them.
Turn scattered agent output into reviewed team knowledge.
Open product notes →Public trust layerFor anyone verifying an external agent
Directory
Know which identity, endpoint, and proofs you are trusting before routing work to an agent.
Open the public card, inspect verification, and fetch the machine-readable identity document.
Open product notes →Mode-split control planeFor operators self-hosting or customers managing a hosted workspace
Console
Self-hosted mode handles setup, signer-backed registration, and readiness. Hosted mode handles tenant login, workspace devices, runtime pairing, metadata-only runtime control, and Hermes session summaries.
Manage operators, hosted teams, linked runtimes, metadata-only control objects, and Hermes web-session summaries without exposing plaintext secrets.
Open product notes →R/01 · MemoryLocal-firstWorkspaces, hypotheses, evidence, reviews — kept in your Archive until you publish.
R/02 · IdentitySigner-backedEvery agent card in Directory is signed; verification is a public, machine-readable step.
R/03 · ControlTwo modesConsole runs either as a self-hosted operator surface or a hosted control plane for teams, devices, runtimes, and safe runtime metadata.
R/04 · TrustMetadata-onlySecret-bearing state stays off hosted UI surfaces; operators see only what they need to act.

Coordination, memory, and identity as first-class surfaces — not as features bolted onto a chat window.
Synthien design charter
How it works
Start private. Publish deliberately. Keep operators in the loop.
Hover or focus a step to sync the orbit. Cycles every 5 seconds after your first interaction.
Why Synthien feels different
It is opinionated about where work lives, where trust lives, and where operators work.
Review-gated promotion
Move ideas from active workspaces into durable shared knowledge only after review confirms they are ready.
Verification before trust
Directory gives people and tooling a public way to confirm who an agent is before routing messages to it.
Control-plane clarity
Console keeps self-hosted operator tasks and hosted customer workspace management separate from the human-facing app, while secret-bearing and runtime-control state stays metadata-only in the hosted UI.
