🏢 express × enterprise-saas

Ship enterprise saas on Express with sensible defaults.

Express is a TypeScript workable choice for enterprise saas. GreatCTO auto-detects both — adds the enterprise-saas archetype overlay, wires enterprise-saas-specific gates, and runs 34 specialist agents around your existing Express workflow.

What changes when GreatCTO joins your Express project

Detection → overlay → gates → reviewers.

1 · DETECT

Stack + archetype

GreatCTO reads your package.json and detects express + enterprise-saas archetype from signals: imports, file structure, env vars, README hints.

2 · OVERLAY

Archetype pack

Attaches the enterprise-saas archetype overlay: archetype-specific reviewer + compliance gates. Override if your specifics differ; the defaults are sensible for Express-style projects.

3 · GATES

Express-aware reviewers

qa-engineer runs tsc --strict / eslint / vitest --coverage; security-officer checks for prototype pollution + XSS sinks; performance-engineer reviews bundle size + cold-start times.

4 · MEMORY

Cross-project lessons

Bugs you've hit before in other Express projects (connection-pool exhaustion, ORM N+1 queries, retry storms) — the agent's Step 0 includes the prior detection order. MTTR drops 94 % on second occurrence (methodology).

Concrete walkthrough.

$ cd my-express-app && npx great-cto init
✓ scanning manifests… found package.json
✓ stack: express (TypeScript)
✓ archetype: enterprise-saas
⚠ archetype + stack combo is unusual — review overlay manually
✓ 34 agents ready

$ /start "add enterprise-saas feature"
▸ architect drafting ARCH-enterprise-saas.md…
▸ pm decomposing into beads tasks…
⚐ gate:plan — your approval needed

Approve → 3 senior-devs run in parallel worktrees → 5 reviewers fan out in parallel → gate:ship → deploy. One real run walked stage-by-stage: /proof.

⚠ Honest caveat

Express (TypeScript) is not a typical fit for enterprise saas. The archetype overlay still attaches, but you may want to override defaults more aggressively. Check the enterprise-saas archetype page for the typical stack list and decide if your case is the right tool / right archetype.

Architecture

Every step of the pipeline, transparent.

No black-box "AI does it all" loop. GreatCTO is a deterministic state machine — 8 stages, 22 nodes, 2 human gates. Every node maps to a real agent on GitHub. Inspect the state machine →
