System

Simple SaaS MVPs

Working web apps with auth, payments, and a real customer use case.

Micro-SaaS is the leverage play of the decade. One narrow tool, one obvious buyer, one recurring price. With Lovable + AI as your dev team, you can ship a real app in a week and bill for it like a real product.

Time to ship

7–14 days for the MVP

Pricing range

$9–$49 per user / month

Realistic 90-day outcome

MVP shipped in 7–14 days. First 20 paying users in 30–60 days from focused outreach. Realistic path to $1k–$5k MRR in 90 days with consistent shipping. Real businesses (not lifestyle wishes) live above $10k MRR.

What you'll actually build

  • A focused single-purpose web app (one job done excellently, no scope creep).
  • User auth, profile, and tier-based access (free / pro / team).
  • Stripe checkout, subscription billing, customer portal — wired and tested.
  • An AI feature at the core (gen, summarize, classify, automate) powered by an LLM API.
  • A landing page that pre-sells the app and a dashboard that delivers it.

Real-world examples

'PromptVault' — team prompt library

Teams store, tag, and version their best prompts. $19/user/mo. Sells to agencies and content teams.

'PinScribe' — Pinterest caption generator

Paste a pin URL, get 10 SEO-ready captions. $14/mo. Pinterest creators eat this.

'AuditBot' — local SEO audits

Enter a business URL, get a branded PDF audit. $99 one-time or $29/mo unlimited. Agencies white-label it.

'ClientBrief' — onboarding form → project plan

Client fills a form, AI returns a scoped plan + estimate. $39/mo. Freelancers replace 4 SaaS tools with it.

How you build it, step by step

  1. 01

    Pick a sharp, painful, narrow problem

    One persona. One job. One outcome. 'Cold-DM script generator for B2B SaaS founders' beats 'AI marketing assistant.'

  2. 02

    Spec it in Claude

    Get a one-page PRD: user stories, screens, data model, billing tiers. This becomes the brief for Lovable.

  3. 03

    Build the MVP in Lovable

    Auth, dashboard, the one AI feature, and Stripe — typically 2–5 days of focused building.

  4. 04

    Ship to 20 early users

    Manual outreach to communities. Half free, half paid. Collect feedback, fix the top 3 issues, raise price.

  5. 05

    Layer automation with n8n

    Trial reminders, churn alerts, customer-success nudges — all hands-off.

How it makes money

  • $9–$49/mo per user (most micro-SaaS lives here).
  • Lifetime deals ($79–$199) on AppSumo or your own list to fund early growth.
  • Annual plans at 20–30% discount — improves cash flow and lowers churn.
  • White-label / agency tier at 3–5x personal price.
