OpenSail
Open-source agentic software work
We just open-sourced OpenSail. It’s a workspace for building agents, apps, workflows, automations, and deployable software in one place.

A few months ago, we posted an open-source UI code generation model on Reddit and Hugging Face. Went to sleep. Woke up to thousands of downloads.
We hadn't even planned to build a company.
But the signal was loud: developers want AI dev tools they can actually own and control — not black boxes they're renting.
So we built Tesslate. Studio, Agent Builder, Designer, Forge. Open source, runs locally, you own the code.
Honest lesson: open source gives you distribution, not revenue. I should have been talking to customers 3 months earlier.
Launching today. Free, no credit card: https://tesslate.com
