Open source", "summary": "Open Mercato released cezar, a free MIT-licensed open-source orchestrator that runs Claude Code, Codex, OpenCode and other coding agents in parallel on a laptop or VPS using existing agent subscriptions rather than API keys. Created by Patryk Lewczuk, cezar gives each task its own git worktree, gates every step on workflow checks such as npm test, and queues runs that survive restarts, with a one-command Ubuntu VPS install (`npx cezar-run server-install --platform ubuntu-vps`) adding HTTPS and a login. The tool requires macOS, Linux or WSL2 with Node 20+, needs no account or database, and is pitched at developers who want backlog issues turned into reviewable pull requests while offline.", "body_md": "### Issues straight to agents\n\nHand a GitHub, Jira or Linear issue to an agent in one click. The PR comes back to you.\n\ncezar runs **Claude Code, Codex, OpenCode and other coding agents** in parallel on your laptop or a VPS, on the subscriptions you already pay for. No API keys. Queue the backlog, close the laptop, review the PRs from your phone.\n\nmacOS, Linux and WSL2, Node 20+. Free and open source (MIT). No account, no database. [Watch the demo](https://www.youtube.com/watch?v=nNLJm9gArnE)\n\nIntroducing cezar\n\nQueue tasks, hand over GitHub, Jira or Linear issues, or let automations start runs on a schedule. cezar drains the queue in parallel worktrees, runs your checks after every step, and has the PRs waiting for review when you are back.\n\nThe night shift\n\nSchedules, GitHub polls and tracker events start runs while you are offline. When every slot is busy, new runs wait in the queue. Every run gets its own worktree and its checks, and the PRs wait for you in the morning.\n\nStart tasks, answer questions and review the diff from wherever you are.\n\nDispatch\n\nSwitch on Dispatch and a big task splits itself. The thinking stays on a strong model, the routine work goes to a cheaper one, and every result reports back to you.\n\nCosts are illustrative.\n\nTake the tour\n\nType what you want done, in plain words.\n\nThe problem\n\nLaptop-bound\n\nAgents live in a terminal session. Close the laptop, lose Wi-Fi or go to bed, and the run dies with it.\n\nOne at a time\n\nThe rest of the backlog waits in your head, not in a queue. Nothing moves unless you are typing.\n\nNo guardrails\n\nNothing runs your tests before the agent calls it finished. You find the breakage in review.\n\nToken bills\n\nOrchestrators usually want API keys billed per token, on top of the subscription you already pay for.\n\nWhat is cezar\n\nConfig steps\n\n0\n\nNo setup. cezar picks up the agent CLIs you already have installed\n\nUptime\n\n24/7\n\nOne command puts it on a VPS with HTTPS and a login\n\nAgents\n\nMix\n\nClaude Code, Codex, OpenCode and more. Pick one per step\n\nPrice\n\n$0\n\nMIT open source. You pay only for the plans you have\n\nFAQ\n\nAn open-source orchestrator for AI coding agents. It runs Claude Code, Codex, OpenCode and other coding agents in parallel, each task in its own git worktree, on your laptop or 24/7 on a server, with a web cockpit to watch, steer and review everything.\n\nNo. cezar drives the agent CLIs you are already logged into, so runs use the subscriptions you already have. There is no cezar account and no database either.\n\nClaude Code, Codex, OpenCode and pi today, with more added as new agent CLIs come out. Pick one per task or per workflow step, and switch a task’s runner, model or account mid-thread without losing the conversation.\n\nRun `npx cezar-run server-install --platform ubuntu-vps`. It sets up HTTPS, a login and a system service, so the cockpit is reachable from anywhere, phone included. Prefer not to run a server? Try it on [Open Mercato Cloud](https://openmercatocloud.com/247agentic-cear).\n\nAs many as your machine can handle. Set a parallel limit for the workspace or per project and the rest waits in a queue that survives restarts. Running tasks can dispatch subtasks of their own, and a memory ceiling pauses heavy runs so the queue keeps moving.\n\nNot without you. Workflow checks like npm test gate every step (exit 0 means pass) and failures go back to the agent to retry. Every run with changes waits at a review gate, and nothing merges on its own.\n\nAutomations: a schedule, a GitHub poll, a PR review, or a Jira or Linear event. With Autonomous on, the run never stops to ask and finishes with the PR ready for review.\n\ncezar is free, MIT-licensed open source. You pay only for the agent plans you already have, and the Dashboard shows reported usage and cost per task and project.\n\ncezar was created by Patryk Lewczuk at [Open Mercato](https://www.openmercato.com/), the open source CRM/ERP framework company founded by Piotr Karwatka, who previously co-created Divante, Open Loyalty and Vue Storefront (later Alokai, a Y Combinator company with a $40M Series A).
