AI intelligence, connected

Software that refuses to fake done.

Selran builds local-first, Claude-native tools for work that has to hold up — autonomous code audits, design systems, quality-gated loops, and a private runtime that keeps your data on your machine.

What we build

Five apps, ready today.

Each one is local-first and built on the Claude substrate. More of the Selran suite is on the way.

Why Selran

Built for work that has to be defensible.

Local-first

Runs on your machine. No cloud backend, no telemetry — your data and code never have to leave the device.

Verification, not assertion

A passing verdict is grounded in real analyzers and a separate judge — a fact in a file, not a claim in a transcript.

Claude-native

Ships as Claude Code plugins and an MCP runtime, built on the Claude Agent SDK and the MCP standard.

Governed & auditable

Ed25519-signed audit trails, blinded judges, and human review gates — so the loop never decides to ship on its own.

The connective tissue

One runtime, many tools.

Selran Hub is the local daemon the other apps detect and light up against — one well-known port, one MCP bridge, everything on device.

Support

Get up and running.

Selran is local-first and Claude-native — install the runtime, add the plugins, point them at your work.

Install Selran Hub

The local runtime (one daemon on 127.0.0.1). The free plugins also work fully on their own.

Add the plugins

Drop Greenloop, Rubriforge, or Design Director into Claude Code or your MCP client.

Point at your work

Aim them at a repo or project — they detect the Hub and light up against it.

FAQ

Common questions.

Is my data private?
Yes. Selran is local-first. Selran Hub binds the loopback address only, with no cloud backend and no telemetry — nothing leaves your machine except an opt-in update check that is off by default.
Which apps are ready today?
Five: Greenloop, Selran Design Director, Rubriforge, Selran Hub, and Context Keeper. More of the Selran suite is on the way.
How are they licensed?
Selran Hub is MIT. Greenloop is free for personal, non-commercial use. Rubriforge is built and hardened, with licensing and marketplace details finalizing as testing completes. Reach out for current terms.
Do they need an API key?
No key is required for default use — the apps run as Claude Code plugins on the Claude substrate. Rubriforge can also be driven headlessly via the Claude API/SDK.
How do PHI and confidential work get handled?
Rubriforge treats confidential domains (e.g. medical peer review, grant review) as local-only: a local judge is mandatory and external egress is blocked. A deterministic PHI guard blocks unless the run is provably local.
