The control plane for AI-assisted development

Agents write the code. You decide what ships.

Describe the product in a sentence, the way you would to any prompt-to-app tool. What comes back isn't a demo you rebuild before anyone can use it — it's a repository that already went through 13 stages of reuse, design and executable gates, and parked at the 3 points where a person is legally on the hook. Self-hosted. Row-level security enabled and forced from the first commit.

No card. No account for intake. Runs on your machine or ours.

One method, whatever you're starting from

The same 13-stage pipeline carries a blank page and a codebase you've run for a decade to the same place: staged, reviewed, operated.

New product

From a sentence to a reuse map

Stage 1 checks what you're describing against the catalogue before anything is written. The part before that sentence — market research, finding the customer's actual pain point — isn't a Rathvan screen. It's the conversation you have first, in your own head or a doc; the pipeline picks up at the reuse map and carries it from there.

stage 01 onward
Existing product

From a repository to a baseline

Point it at a legacy repo instead of a blank page. It reads the tree and the commit history at one resolved commit — no diffs, no old file versions, secrets and PII scrubbed before anything reaches a model — writes a cited baseline document, and proposes a roadmap grounded only in what it actually read.

designed — no code yet

Both paths rejoin the same run: PRD → design → build → the executable gates → staged → the operational-readiness gate before anything is called live. Modernising what you already run and building what doesn't exist yet are one pipeline, not two products.

Two things a five-minute demo never has to solve

They're also the two questions a finance or security reviewer asks first, and the reason a prototype stays a prototype.

Your books

Never a Rathvan ledger

QuickBooks Online, Xero, Zoho Books, or a Tally bridge you run on your own machine — Rathvan reads and posts through your accounting system's own API. There's no platform ledger to reconcile against, because there isn't one: balances, journals and the chart of accounts stay the system your auditor already trusts.

designed — no code yet
After it ships

The pipeline doesn't stop at deploy

Stage 10 instruments the deploy boundary, the first error after boot, and the number that actually catches a stuck queue — what's left, not what's processed. Stage 13 is the operational-readiness gate: a runbook, a named owner, a rollback that needs no deploy, and the query that proves it's working, before anything is called live.

What a diff review cannot give you

Four things that have to be decided before the code exists, or not at all.

Custody

The key never leaves

Credentials sit encrypted on hardware you control. No key, no storage — plaintext is never a fallback. Nothing is indexed off-box.

self-hostedmode 600
Access

Authorisation is one lookup

Four roles and a viewer who reads a design without being able to approve it. Teams address work and grant nothing. The last owner cannot be removed.

RBACSCIM
Ceiling

STAGED is the last state

No method in the platform expresses the move past it. Production needs a person, and the refusal is structural rather than configured.

◆ human
Provenance

Approval binds to a version

Every stamp attaches to the exact artifact under review. Every transition writes an audit event naming its actor — including the refusals.

Rigour by stakes

A workspace belongs to exactly one track. The track decides which stages apply and how many gates block.

TrackShips toGatesWhat it forces
Build or edit a web appproduction◆ ◆ ◆All thirteen stages, all three gates, nothing relaxed. Editing an existing codebase is the harder half — bounded ownership, minimal diff, and the reuse map is the entire job.
Create prototypesnowhere—Tightens the two stages people skip; relaxes the rest. A prototype must be structurally incapable of shipping — separate namespace, no production credentials, an expiry. Promotion is a restart, not a merge.
Convert designs to codepull request◆Round-trip fidelity or bounded ownership — a generator that rewrites a component discards every hand-edit since. Tokens are a failing gate, not a review comment.
Manage contentproduction◆Publishing changes data, never code. If a content change needs a build, an engineer is back in the loop and “without developer dependency” is false.
Marketing sitesproduction◆ ◆A marketing page fails invisibly. Deep-link objects must exist — a 404 rewritten to 200 renders as a blank page with an empty console. Verify by downloaded size, never status code.
E-commerceproduction◆ ◆ ◆Everything tightened, plus the full security pass. The amount is server-priced from the catalogue, always. Not yet in the kernel: catalogue variants, cart, inventory, fulfilment, returns, tax.
Personalizationproduction◆ ◆Never average across variants — the aggregate hides the losing one. Assignment must be stable and recorded, and the stopping rule is decided before launch.

A refusal, in full

Proof is a real run that stopped, not a happy path.

You do not have to build it to get it

Four capabilities are decoupled from the catalogue. Take them as a service today, or generate them into your own repository. Same source, same gates.

Publication

Workflow, review, scheduling, publishing and content governance for people who publish for a living.

Three ways to run it

The console is a client. It is only ever pointed at a builder somebody runs.

CLI

Scaffold and run

No account. Node 20+, JDK 21+, Docker. Prints the plan — every file, every skip, with the reason — and writes nothing until you confirm.
