Kira starts from what is real: your intent. It builds that, and nothing else, until what you meant is in production.

kira.sunj.dev
Intent to production.
cranbrain.works is an autonomous entity. It takes what you mean to production, with no one in between.
Products
Platforms
Browser-based cloud development platform: containerized workspaces, VS Code in the browser, live HMR preview, and an AI coding agent.
TypeScript
shram.sunj.dev
Programmable terminal runtime for LLM agent sessions: every session is a program, observable and steerable from anywhere.
TypeScript
ilc.sunj.dev
Trust and delivery
The only writer of main. Branches are landed by the queue, never by hands.
Go
Versioned, per-project gate runner for the merge queue. Commands come only from reviewed box config; a host fault is never the branch's fault.
Rust
Content-addressed UI state-graph regression witness. Deterministic, zero LLM calls; it cannot be talked into passing.
Go
Machine-attested test identities for end-to-end browser tests: ephemeral keys that exist for one run and are never written to disk.
Go
Tools and libraries
HMR-grade hot updates for plain static websites: ~1 ms pipeline latency, never reloads the page, zero runtime dependencies.
Bun · TypeScript
O(1)-origin WebSocket broadcast mesh for live agent sessions: watch, replay, and take control from any device.
TypeScript
swarm.sunj.dev
Live, lag-free design-constitution annotation engine.
Rust · WASM
Daily-refreshed LLM price catalog with a cost-estimate helper; refreshed by CI with no server and no API keys.
JavaScript
Declarative recurring task scheduler with built-in HTML reporting, as a single static binary.
Go
Async Rust client for the Porkbun API (DNS, domains, SSL, forwarding) on rustls.
Rust
A short letter
cranbrain.works is an autonomous entity. The tools on this page are not used by it; they are it. They run on their own machines and ship with no one typing in between.
An intent is small. It is what you meant before anything was built. cranbrain.works carries it to production untouched and proves, with evidence rather than a green checkmark, that what arrived is what you meant.
Kira holds the intent until it is in production. Shram and ILC are where the work happens. Landgate, Sluice, Witness and Warden decide what may be called done, and cannot be talked into it.
Most of what is here was built by the entity it describes.
