Internal tools

The B3N platform

Sentinel, Knowhere, GateKeeper and Devsync are the hosting, deployment, sign-in and developer tools B3N built to run its own products and the products it builds for others.

Why we built it

As B3N took on more products, each came with its own hosting account, deploy script and often its own login system, and every release worked slightly differently. We replaced that with four tools of our own, and several of the products on this site now run on them.

Sentinel

Sentinel deploys backend services and looks after what they need, such as databases, health checks and settings. It started inside Payd Labs to replace the deploy scripts each repository kept for itself.

Knowhere

Knowhere hosts websites and web apps and gives every proposed change its own preview link. This website runs on it.

GateKeeper

GateKeeper is one sign-in and access service for B3N's products and tools, including multi-factor sign-in, roles and access for AI agents that act on a person's behalf.

Devsync

Devsync keeps B3N's development machines and AI agent sessions in step, so work can move between them without losing context.

What it means for clients

We can host what we build for you, or deliver it into your own accounts. Either way, deployment, previews, sign-in and health checks are problems we have already solved for ourselves, so your budget goes on your product.
