Saki Studio drives an AI coding agent through a real product pipeline — write a spec, see a clickable prototype, then watch it build, QA, and code-review itself slice by slice. Hosted in an isolated sandbox, driven by your own model key.
Bring your own key · you pay only your tokens · isolated cloud sandbox
Most AI coding tools hand you a suggestion and wish you luck. Saki runs the whole disciplined journey — and holds the line on quality at every step.
Write a PRD, get a clickable prototype in your real design system, then let the agent build, QA, and code-review every vertical slice on its own. Structure, not vibes.
/prd → /proto → /buildPlug in your Anthropic key — or a budget model like DeepSeek, Kimi, or GLM — and pay only your own tokens, at cost. No markup. The subscription buys the platform, not the model.
no token markupEvery build runs in its own ephemeral cloud sandbox — resume from any browser, no local toolchain to babysit. Your key lives in memory only and is wiped the instant the run ends.
key-wiped on teardownEach stage hands off to the next automatically. You approve the shape early; the agent does the grind and reports back with green checks.
Turn an idea into a reviewed PRD with vertical slices and acceptance criteria.
A clickable preview built from your real components — see it before it's built.
Autonomous, slice by slice. Plans, implements, commits, branches, pushes.
Every acceptance criterion is run and checked off — pass or fail, no guessing.
A fresh-context code review before anything lands. Issues flagged by severity.
No token reselling, no per-seat games — the subscription buys the hosted studio and the workflow.
One simple subscription — the price is revealed when we open.
Launching to a private beta soon
You already have a model key. Reselling tokens would mean a markup on every call — so instead you connect your own and pay exactly what the model costs. The subscription pays for the hard part: the hosting, the sandbox isolation, and the pipeline that keeps quality honest.
Straight answers — no asterisks.
No. Your key is encrypted at rest and decrypted only inside your own sandbox's memory, for the length of a run — then wiped on teardown. It's never written to logs or returned to the browser.
Anthropic by default, or a budget Anthropic-compatible model — DeepSeek, Kimi, or GLM. You connect the key and pay that model's tokens directly, at cost.
The hosted platform and the workflow: hosting, sandbox isolation, and the PRD → proto → build → QA → review pipeline. Never the tokens — there's no markup, ever.
Saki wraps one in a disciplined product journey and runs it hosted — so there's no local toolchain to install or babysit, and you can resume a build from any browser.
Saki Studio is in the final stretch before a private beta. There's no sign-up yet — check back soon, or say hello at saki@saketek.id.
