02 / How we build

Read the code, host it yourself for free, or let us run it for you.

01

Open by default.

New projects ship under AGPL-3.0. Read the code, change it and run it on your own infrastructure. Anyone who offers a modified version as a service publishes their changes too.

02

Agent-native.

Every product works from your AI agent over MCP, with a CLI, an API and a dashboard alongside. You ask in plain language; the agent does the work.

03

The human approves.

Agents do the work, people decide what reaches other people. An email or a post waits for your approval before it goes out.

04

Yours to run.

Self-host for free and keep your data with you, or let us host it. The cloud is a convenience, not a lock-in.

03 / Who builds it

A small studio, building in public.

“I started Polynode to build AI-native products that solve real problems. Now we're making them open source, so the people who use them can read them, run them and make them better.”
The story

Polynode began as a studio for focused, AI-driven products, built in-house and run with as little manual work as possible. Building them taught us that the best way to put this software in people's hands is to open it up: let them read the code, run it on their own infrastructure and improve it, with a hosted version for those who'd rather not.

04 / FAQ

Questions, answered plainly.

A small product studio. We build AI-native software that your AI agent can run, and we're making it open source: Meerko, our GTM agent, is the first. Each product can be self-hosted for free or used as a hosted cloud service.
