Most people overthink their first SaaS project. They spend weeks searching for the perfect idea. Truth is, most “perfect ideas” never ship. But momentum beats perfection.

Here are 10 tiny, focused SaaS ideas you can actually build this weekend. Some of them already exist and that’s the point. You don’t need to reinvent the wheel. You need to ship.

1. Simple Waitlist Manager

A lightweight app where people can:

Join your waitlist
Get a referral link
Track their spot

Bonus points if you add Resend email confirmations or a leaderboard. Perfect for testing demand.

2. Landing Page Feedback Tool

Let founders drop their URL, then collect structured, up voteable feedback from the community (or GPT).
Charge for featured reviews or premium audits.

3. Screenshot to Website Copy

User uploads a screenshot of a landing page → GPT rewrites the copy to be more clear, more persuasive, or more niche.
Narrow positioning. Big potential.

4. Content Planner for Product Launches

Calendar view + checklist + templates.
Make it super opinionated: “Day 1 - Tweet this. Day 2 – Post here. Day 3 – Email this.”
You already built parts of this in CoLaunchly.

5. Reddit-to-Startup-Idea Scanner

Input subreddits → scan for pain points → get summarised insights and product ideas.
You already have this as a side tool — could spin it into a standalone product.

6. Personalised Tweet Generator for Indie Devs

Answer 3 questions → get 10 tweet ideas with structure and tone.
Optional: connect X API to post automatically or track engagement.

7. Invoice-from-Chat Tool

Paste a conversation (email, chat, etc.) → extract client name, deliverables, price → generate invoice.
It’s boring, but useful. Add a Stripe Pay Now button and you’re golden.

8. Micro-analytics Dashboard

Privacy-focused, 1-line JavaScript snippet.
Show page views, referrers, and conversions. No login.
Host it cheap. Charge $5/mo. Clean UI wins here.

9. Launch Retrospective Maker

Paste your launch thread, posts, and screenshots → get a clean, visual retro with graphs, quotes, and “what worked.”
Perfect for Product Hunt or Indie Hackers write ups.

10. AI-Powered Idea Validator

Describe your idea → get:

Use cases
Target personas
Pain points
Viability score

Let users export or save ideas. Could be the core of a startup studio toolkit.

Final thoughts

You don’t need funding. You don’t need a big team. You need a tiny idea with a clear user and a simple outcome.

Pick one, make a basic UI, plug in OpenAI if needed, and ship it.

You don’t need a unicorn. You need momentum.
