Probably the best
developer platform
in the world.
Drop a lightweight agent into your clusters and see every workload across all of them: owners, exposed services, RBAC risk, Helm and GitOps status. The catalog, search and docs come built in.
Backstage-compatible · your catalog-info.yaml files just work · *probably.
Your whole platform at a glance, discovered automatically.
How it works
Connect. Map. Ask.
Three moves. Shoehorn does the wiring in between.

The K8s agent, explained
Your cluster talks out.
Nothing reaches in.
Drop a lightweight agent into your cluster. It watches your workloads and pushes what's running up to Shoehorn over a single outbound connection.
- No inbound access. No open ports, no firewall holes, no VPN into your cluster.
- Real-time. Deploy something and it shows up in the catalog within seconds.
- GitOps-aware. Understands ArgoCD and FluxCD sync status out of the box.
Key features
Everything ships together
Catalog, search, docs, governance and operations: one service in your stack. No plugins to maintain.
A catalog that builds itself
Every service, who owns it, what it depends on, where the docs live, all discovered from your repos and clusters. Nobody has to hand-write a single YAML file.

See the blast radius before you ship
Trace dependencies 1–5 levels deep. Know exactly what calls the endpoint you're about to deprecate, before the incident, not during it.
Search that actually finds it
Hybrid keyword and vector search across services, docs and APIs. Stop asking in Slack who owns the thing that's on fire.

AI-ready
Plug your AI assistant
into your platform
Shoehorn ships a read-only MCP server. Point Claude, Cursor or Copilot at it and they answer questions about your stack from your real catalog: who owns a service, what depends on it, where the docs live. Grounded in live data, not guesses.
- Read-only and safe. Assistants read context, they can't change anything. The CLI stays the path for writes.
- Any MCP client. Claude, Cursor, VS Code, and more.
- Grounded in your catalog. Answers cite real services, owners and docs.
/charge?3 services call
/charge: checkout-web, ledger, billing.Runbook: payments/on-call.
Why Shoehorn?
It runs as part of your stack. No portal team needed just to keep it alive.
Build with Shoehorn
Terraform, CLI, REST or MCP. Every action is an API. Same data underneath.
