saas-launch — provider-aware SaaS production system

A reusable agentic software-production system taking vertical SaaS from ideation through PRD, architecture, implementation, verification, deployment, and launch preparation — public developer tooling and the studio's internal factory.
Fabrica lanceolata — SaaS production system, cultivated 2026
Field notes
The context
One-off agent builds don't compound: quality, handoff, and verification differ per project, and a longer prompt is not a production system. The studio needed a repeatable way to take a vertical SaaS from idea to verified deployment.
Cultivation
What I built
- Created saas-launch as both public developer tooling and the internal production system used to build production-shaped SaaS products.
- Designed a gated ideation → PRD → prototype → build workflow with provider detection, explicit approvals, build-now and handoff paths, reusable templates, and evidence-backed completion.
- Built four cumulative agent-harness tiers, from minimal repository rules through structured multi-agent delivery and autonomous factory workflows.
- Standardized delivery around pnpm and Turborepo, shared schemas and design systems, Supabase/Postgres/RLS, PWA behavior, unit tests, Playwright E2E, CI, deployment, and launch collateral.
- Evolved the workflow toward provider independence — Codex as the current primary production environment, other models routed selectively to independent review, creative exploration, or game prototyping.
Root system
How it works
Sequential, human-gated phases (ideation, PRD, prototype, build) over a deterministic pnpm + Turborepo scaffold. Four cumulative harness tiers govern how much autonomy agents get; handoffs persist between phases; an independent review pass and lint / typecheck / build / test evidence are required before anything counts as done.
Harvest
Outcomes
- Six production-shaped vertical SaaS products built through the system: Labada, Kintab, BaseShear, Backten, Kolekta, and Resibo.
- Labada and Kintab are preparing for founder-assisted local launch — no customer adoption or revenue is claimed before validation.
- The same system doubled as the R&D harness for four browser-game prototypes in the interactive systems lab.
Repeatability comes from contracts, gates, and evidence — not from a longer prompt. Human approval at phase boundaries is what keeps agent-heavy delivery honest.
