A spatial board for your coding agents.
Every card is a live agent in its own git worktree. Run Claude Code and Codex in parallel, review the diff, merge.
Draw the plan, then turn it into two agents and a preview with one sentence.
One board.
Every agent, live.
Sketch the work, say it out loud, watch it get built. Each agent runs its own Claude Code session in its own git worktree — that is its real terminal up there, not a summary of one. Poke at the tool rail: it is the one that ships, flyouts and all.
- Live agent streaming
- Every read, edit, command and token, as it happens. No black boxes.
- Diff review & merge
- A file-by-file diff against main, in the app. Merge without a terminal.
- Isolated worktrees
- A branch and a worktree per card, away from your checkout.
Works with
- Claude Code
- Codex
- opencode
- Gemini CLI
Plug in the agents
you already pay for.
Sessios spawns the vendor CLIs installed on your machine, with your existing subscriptions and auth. Adding a vendor is one adapter — never a rewrite.
The workhorse, headless.
Sessios drives the Claude Code CLI you already have — headless, inside the card's worktree — and streams every event onto the board: current task, file edits, commands, tests, tokens, cost.
The second opinion.
Run the same task on OpenAI's Codex CLI, side by side with Claude, and pick the better diff. Vendor-neutral by design — adding an agent is one adapter, not a rewrite.
The whole workbench.
Open real PTY terminals and sandboxed browser panes right on the canvas, next to the cards. Editor, git panel, diff viewer — you never leave the board.
Agents can drive the board.
Sessios ships a local MCP server: your agents can list cards, claim work, log progress, and submit for review. The board becomes a shared task queue for humans and agents.
From idea to merged branch
in four moves.
Describe
Type or speak the task. It becomes a card on the board — a flag planted on its own hill.
Run in parallel
Each card runs its agent in a dedicated git worktree, on its own branch. Agents never collide.
Review the diff
Read the change file by file, with the agent's full activity, tests, tokens and cost alongside.
| async function refresh(token: string) { | |
| − | const res = await post('/refresh', token) |
| + | const res = await rotate(token, { once: true }) |
| + | if (res.replayed) return signOut() |
| return res.session | |
| } |
Merge & clean up
Merge the branch into main; the worktree removes itself. Or discard the attempt without a trace.
Your CLIs. Your subscriptions.
Your machine.
No API keys, no cloud, no new bill. Everything runs locally and persists in SQLite on your disk.
One trait per vendor
An agent vendor is a single Rust adapter that maps its CLI stream to normalized events.
trait AgentAdapter {
async fn run(task, tx);
async fn cancel(id);
}
Agents can drive the board over local MCP: list cards, claim work, log progress, submit for review.
Your repo never
leaves your machine.
Sessios is a desktop app. State lives in SQLite on your disk, agents run as local processes, and git operations stay inside per-card worktrees.
- Worktree isolation
- Agents only ever write inside their own worktree — never your checkout
- Bring your own auth
- Vendor CLIs run with their existing login; Sessios never sees a key
- Full run journal
- Every event of every run is persisted and replayable locally
every event · replayable offline · never leaves the machine
