OpenPolsia is an open-source project started by Jan Wilmake on March 22, 2026. It is modelled on Polsia — an autonomous AI agent visible as the @polsia account on X — which runs multiple businesses simultaneously and posts updates about its operations. OpenPolsia is Jan's attempt to replicate and extend this concept with open-source code.[1]
Polsia (@polsia on X) is an AI agent that autonomously manages and describes business operations. Its X posts read as automated business status updates. On March 21, 2026 it posted two examples of this pattern: "New company running today. A video editing service built by a creator who knows what creators actually need. The editing-as-a-service market is wide open for someone with real production instincts." and "Now running ops for a platform that turns drawing into a daily habit. No competition, no pressure. Just consistency and a community that shows up. The Duolingo of sketching, basically."[2]
This makes Polsia a precursor to agentic business management: rather than a human describing a startup, an AI agent runs the day-to-day operations and documents them publicly. The model combines business task orchestration with multi-business context switching.
The Polsia concept is distinct from conventional AI product builders — the agent does not simply generate a business plan, it autonomously operates multiple businesses simultaneously in an ongoing, persistent fashion, posting publicly about its decisions and operations on X.
Jan chose to open-source the replication rather than reverse-engineer the original or contact the Polsia team. As of Day 3 (March 24, 2026) he was focused on achieving feature parity with the original Polsia before adding improvements or diverging. There is no indication from the archive that a separate closed-source Polsia.md entry is warranted — Jan engaged with Polsia purely as an inspiration/model and OpenPolsia is the only product he built in this space. The two can be understood as the inspiration and the open-source response respectively, both covered in this entry.
Jan started with a focus on feature parity to Polsia, building out in daily increments:
Core capabilities targeted:
On the same day as the Day 3 OpenPolsia update (March 24, 2026), Jan was actively building the execution infrastructure that OpenPolsia would depend on. He asked: "Can I have a Cloudflare sandbox where the user is logged in into their own stripe, git, gh and wrangler, then expose the terminal with all the commands as an AI tool with proper sleeping built-in when the tool isn't used?"[1]
Later that day he answered his own question: "result — it worked for gh, stripe, and wrangler", publishing the code at github.com/janwilmake/sandbox. The sandbox uses Cloudflare's sandbox API with automatic sleeping to minimise costs when the tool is idle. This substrate — a pre-authenticated, sleepable terminal exposed as an MCP tool — is the execution layer that makes OpenPolsia's agentic business operations technically feasible.[1]
On March 25, Jan confirmed the sandbox was working fully after receiving helpful pointers from @firtoz about using tokens for git, gh, wrangler, and stripe CLI authentication.[4]
OpenPolsia was started on March 22, 2026, during an extremely productive period. In the weeks immediately preceding, Jan also shipped:
| Date | Project |
|---|---|
| Mar 2 | Markdown_Browser launched |
| Mar 5 | uithub open-sourced |
| Mar 7 | uithub-lib published |
| Mar 19 | githuq launched (via forgithub) |
| Mar 22 | OpenPolsia Day 1 |
| Mar 24 | Cloudflare Sandbox completed |
This clustering of launches in March 2026 was the densest shipping period in Jan's post-Parallel AI career, enabled by Claude Code agentic workflows and Cloudflare's tooling.
OpenPolsia has been shown during multiple networking and interview calls in May 2026, serving as a live demonstration of Jan's autonomous agent architecture:
The fact that Jan consistently reaches for OpenPolsia when demonstrating his work suggests it has become his primary "show, don't tell" portfolio piece — a live, running instance of an AI agent managing business operations.
OpenPolsia represents Jan's most direct engagement with the idea of AI agents as autonomous business operators — not just as coding assistants, but as entities that create, run, and describe businesses without human bottlenecks. This connects to his broader philosophy in Agent_Friendly_Web (providing agents with clean information access) and Reciprocal_Networks (independent units operating through reliable APIs). An agent running multiple businesses on autopilot is, in effect, a one-person company operated by a non-person.
