FactoryStarter vs ShipFast — when to pick which

The honest summary

ShipFast helps you ship one SaaS, fast. FactoryStarter helps you run a portfolio of products. Different unit of optimization → different design → different price. If you're only ever going to ship one product, ShipFast is the better tool. If your goal is a portfolio strategy, ShipFast doesn't do that — and FactoryStarter is built for it from the ground up.

What ShipFast does brilliantly

• Single-product opinionated stack (Next.js + Supabase + Stripe).
• Beautiful default landing components — easy to start.
• Lifetime updates, not 12-month-then-renew.
• Massive community of single-product indie hackers.
• Marc Lou's personal brand and tutorial library.

Where ShipFast stops

• No notion of multiple products. Every project is a fresh fork.
• No AI agent layer — Claude/Cursor are exogenous.
• No background monitoring, kill rules, or analyst agents.
• No CLI/MCP boilerplates — it's a webapp shop.
• No playbooks for recurring portfolio decisions.

None of those are mistakes — they're just outside ShipFast's scope. The product was designed in 2023 for the “one indie SaaS” bet, and it nails that bet.

What FactoryStarter adds

• 10 specialized agents. spec-writer → designer → senior-dev → tester → reviewer → devops → tech-writer → marketer → support-bot → analyst. Each one is a Claude Code system prompt with explicit handoff contracts. You stop re-orienting Claude every session.
• 3 boilerplates. Webapp (Next.js + Supabase + Stripe), CLI (Node + Commander), and MCP server (for Claude tools). One license, three product types.
• 5 background monitoring agents. kill-monitor (sunsets dead products), analyst (PostHog anomalies), seo-checker (Search Console), pr-reviewer, dependency-bot. They run on cron — you wake up to a digest, not a fire.
• 8 production playbooks. Ship-day, distribution, pricing-iteration, kill-or-scale, customer-support, refund, growth-experiment, post-mortem. Battle-tested, not aspirational.
• Persistence model. STATE.md + AGENTS.md + PERSISTENCE.md. Sessions resume. Multiple Claude windows cooperate without stepping on each other.

Pricing

ShipFast: $269 lifetime, lifetime updates. FactoryStarter: $149 lifetime, 12 months of updates included, optional $49/year after. We're cheaper because the audience is smaller — the portfolio strategy is a niche inside the indie hacker space — and because we want zero friction for the first 100 buyers to give us feedback.

Decision matrix

• You're convinced about one product idea, you have time, you want a polished landing kit and lifetime updates → ShipFast.
• You've already built one or two products, the boring parts are killing you, and you want a system that compounds across many products → FactoryStarter.
• You're running an agency / consulting practice and want a fast scaffold for client work → either works; FactoryStarter is cheaper per seat.
• You're still picking your first idea → buy neither yet. Ship a tiny project on free tools first.

Disclosure: I have no affiliation with ShipFast or Marc Lou. I bought ShipFast in 2024, shipped one product on it, and learned the limits I built FactoryStarter to address.
