What makes a beginner-friendly micro-SaaS?
- One job, one screen. If your MVP needs more than one primary screen to deliver value, it’s too big.
- Clear input → output. A specific file, text, event, or record goes in; a transformed result or action comes out.
- Immediate monetization. The first paid outcome should be obvious (bigger limits, faster processing, premium export, team seats).
- Draft a 50-word value prop and 3 screenshots (wireframes are fine).
- Publish a simple landing with one CTA: “Get early access.”
- Run tiny tests: 1–2 posts in niche communities, 10–20 cold DMs, a $20 micro-ad.
- Book two 15-min calls with real prospects; confirm the job, price range, and “done” criteria.
- Lock scope to a weekend: one core flow + Stripe checkout in test mode.

Tip: Resist fancy dashboards. The fastest path to value: one list view with a clear action, basic auth, and Stripe checkout.
A 48-hour execution plan (Fri night → Sun night)
- Lock problem, price, and scope.
- Sketch the one screen and write the value prop (“For [ICP], who struggle with [problem], we deliver [result] in [time].”).
- Draft your weekend backlog: 8–10 tiny tasks max.
- Scaffold: create your repo, basic Next.js app, and UI shell.
- Build the happy path: input → processing → output.
- Persist the minimum: one table that stores what matters.
- Add auth (magic links or managed provider).
- Instrument logs (console + simple error boundaries).
- Stripe in test mode: product/prices, checkout link/session, webhooks for success/failure.
- Empty/loading/error states so it feels real.
- 90-second demo video: problem → input → output → price.
- Soft launch: post in one niche community, email 10 prospects, DM 10 more. Book two calls for the week.
Pricing that converts for tiny tools
- Anchor with time saved. “Save 2 hours/week” → $9–$19/mo is fair for personal; $29–$49/mo for teams.
- Avoid free forever at the start; instead, offer a trial or generous free tier with a hard ceiling (e.g., 3 files, 100 rows, 1 project).
- Publish your limits clearly on a Pricing page and enforce in code (it’s part of the value story).
- Grandfather early users. First 20 get a locked, lower price; in public, show the standard price crossed out with an early-adopter badge.
- Free: 1 project, 100 items, community email support
- Pro $19/mo: 5 projects, 5k items, priority email, export
- Team $49/mo: unlimited projects, 20k items, roles, export, priority support
Validation (the 48-hour truth test)
- “2×10×10” outreach: 2 communities × 10 members × 10 DMs (“Can I show you a 60-sec demo? It solves X.”)
- Ask two money questions: “If this worked exactly as shown, what’s it worth per month?” and “When would you pay for it?”
- Collect one pre-payment (or at least a signed “I’ll pay when live” email) before you build Week 2 features.
- Kill ideas quickly. If you can’t book two calls, switch ideas next weekend.
MVP anatomy: the only pieces you need
- Landing: headline (job + outcome), one benefit block, one CTA (trial).
- Auth: email magic link (or managed provider).
- Core flow: a single form or upload, a single action, a crisp result.
- Paywall: Stripe checkout + webhooks in test mode.
- Feedback: one input for “What’s missing?” (stores to DB).
- Demo: 90-sec video (script below).
- 10s: Who it’s for + problem.
- 15s: Show input → output.
- 30s: Walk the single flow (no detours).
- 15s: Price + what’s included.
- 20s: “Try it today” CTA + contact line.
Guardrails for using AI (that actually make you faster)
- Scaffold forms, tables, and basic CRUD routes.
- Draft tests for pure functions.
- Generate copy variants for landing and onboarding emails.
- Data modeling (what to store and why).
- Security and entitlements (who can do what).
- Pricing/limits logic (your business in code).
Post-launch: the “first 100 users” flywheel
- Ship weekly (public changelog + GIF).
- Add one growth surface per week (shareable link, invite a teammate, “Tweet this report”).
- Instrument success (simple event log: signed_up, ran_core_flow, upgraded).
- Write one useful post about the job you solve (not your tool), and link to your landing.
- Keep saying the same sentence. “For [ICP] who struggle with [problem], we deliver [result] in [time].” Repetition wins distribution.
Mini-briefs you can copy/paste (5 best bets)
1) CSV→API (Ops/Analysts)
- Promise: “Turn any CSV into a clean API in 30 seconds.”
- Weekend build: upload → validate → store → GET endpoint, Stripe test checkout.
- Paid moment: bigger files + auto refresh + auth tokens.
- Risks: input variety—start with a fixed schema template.
2) Client Portal Lite (Freelancers)
- Promise: “A clean portal for sharing updates and files with clients.”
- Weekend build: auth, projects table, file upload (S3/R2), notes.
- Paid moment: custom branding + multiple clients + email notifications.
- Risks: storage costs—set sane limits from day one.
3) Screenshot Diff Checker (Design/QA)
- Promise: “Spot visual regressions instantly.”
- Weekend build: upload two images → compute diff → render highlights → download report.
- Paid moment: batch compare + history + webhooks.
- Risks: performance—start with image size limits.
4) Trial-to-Paid Nudge (SaaS)
- Promise: “Contextual emails that turn trials into revenue.”
- Weekend build: ingest simple user events → send 2 templates when actions missing.
- Paid moment: sequences, segments, deliverability analytics.
- Risks: privacy—be explicit about data collected.
5) Release Notes Builder (Dev teams)
- Promise: “Readable release notes from your commits.”
- Weekend build: connect repo → parse commits → generate notes → publish page.
- Paid moment: templates, branding, RSS, private notes.
- Risks: parsing edge cases—start with conventional commits.
