Notes on agentic engineering.
How we build hang4r, and how we work now that agents write most of the code.

Your laptop is just the window: run agents on any machine over SSH
Point a session at any SSH host — the agent, terminals, git, and dev servers execute remotely while you keep the same tiled UI. Your ssh config, your keys, no credentials transported.

Your agents, in your pocket
A phone companion for your desktop agents: live transcripts, diff review, pushes only when an agent needs you — over an end-to-end encrypted bridge the relay can't read.

Give your coding agent eyes: a browser it can drive and assert against
A zero-setup CLI puts the embedded browser under every agent's control — click, type, eval, console, screenshot — so "it works" becomes something the agent proves.

Run five coding agents in parallel without them stepping on each other
Git worktrees are the missing primitive for parallel agents. How hang4r isolates every session and checkpoints every turn.

Your subscription is the API
Why wrapping the CLIs you already pay for beats yet another API-key SaaS — hooks, skills, MCP, and billing included.

Code review that talks back
Inline diff comments that become the agent's next prompt — closing the loop between review and revision.

From coder to conductor
The agentic engineer's loop — dispatch, glance, review, merge — and the tooling it takes to run it all day.
