The open-source releases of SeKondBrain — repos you can clone, software everyone can use, a community that supports itself. Most companies build behind a curtain. We package what we build and put it where you can run it — self-hosted, on your hardware, under your control, without asking us.

What lives here

The registry.

Available now · Apache 2.0
Kemory Community Edition
The shared, permissioned memory layer for your AI’s and agents — self-hosted with Docker, bring your own models and all the knowledge they contain. Namespaces, the Gatekeeper, and the hash-chained audit log are all included; we gate on nothing so you are in control of your data. Connect any MCP-capable AI, such as Claude, ChatGPT or even Notion — web AI’s over OAuth, local clients with a simple key. Kemory for AI’s contains 17 memory tools, from recall and compression to promotion and provenance, so you can centrally gather all of your knowledge and reduce token use at the same time. Kora for Chrome points at your own instance too. This is not just a fast filing cabinet: Kemory gives an AI or agent something it does not have on its own — recall.

Project Hai (repo: Kora_Hai)
Labs initiatives get community editions as we develop them. First in the pipeline: Project Hai — hai is Japanese for embryo, and that’s the design. Started as our founder’s own build, in active iteration and evolving with the team: an embryonic agent kernel, born with seed skills, that heals itself. When it meets a task it can’t do, it checks the shared brain, writes the missing skill through a draft-critique-approve loop, sandboxes it, deploys it blue/green, and remembers it, so no agent ever starts from zero. Each release arrives the same way: a repo, a licence, install docs, and a community to run it with.
Our model

Supported and tested by our community.
That means you.

Community editions are free, open and yours to run — no support desk, no SLA, no guarantee beyond the licence. Help lives in the open instead: GitHub issues, discussions, and people running the same software somewhere you haven’t thought of.

If your organisation needs guarantees — hosting, governance, audit export, someone to call — that’s what the Managed and Business editions are for.

Why open source

Memory infrastructure shouldn’t be
owned by one company.

The model companies can’t build this, because their incentive is to keep you inside. Ours is the opposite: SeKondBrain works beneath whatever AI’s and agents you already use.

Neutrality only means anything if you can see it, run it and check it — so Kemory is Apache 2.0, self-hostable, and internally benchmarked at 87.8% on LongMemEval-500 using open-source models, with the method open.

Contribute

Run it. Break it.
Improve it.

The most valuable contribution is use: run it on your stack, file what breaks, tell us what’s missing. Beyond that — issues, pull requests, docs, and answering the question you solved last month for the person hitting it now.

Open source

Clone it
and go.

Everything here is real, licensed, and running in production somewhere. Install it, and build with the people doing the same.
