Side Project Ideas – Steal These & Build Something Cool

If you're looking for a new side project or SaaS to build, here’s a list of ideas I’ve written down over time. Some might be solid businesses, others need validation—but all have potential.

Feel free to take any of these, adapt them, and run with them. Research is needed for most, but some could be profitable with the right execution.

API & Dev-Focused Ideas

  • API Aggregator SaaS – A gateway that normalizes and proxies different APIs into a unified format.

  • API Usage/Monitor – Enable other developers to create and track their users API usage and create for them: real-time analytics, error tracking, and feedback for their APIs.

  • Spam Detection API – Email, text, and comment spam filtering with blacklist tracking.

SaaS & Tools

  • Landing Page Builder for Idea Validation – Quick setup with email capture, analytics, and stats to test demand.

  • Waitlist Page Builder – Customizable signup pages with email collection, analytics, and notifications (with the option to embed as a widget).

  • White Label LMS as a Service – A fully customizable learning management system.

E-Commerce & Business Ideas

  • Shopify Theme or Plugin – A high-quality, well-marketed Shopify theme or extension.

  • Custom Pricing Page Generator – A tool to generate and manage pricing pages, with templates and an API.

  • Booking System SaaS – A booking tool for barbers, salons, and service businesses (with the option to embed on any site).

AI & Automation Ideas

  • AI-Powered Pitch Deck Builder – An AI tool that suggests tailored pitch deck content and designs.

  • AI Chatbot Widget – A customizable chatbot for support, lead generation, or knowledge bases.

  • AI-Powered Mini-Course Generator – A platform for creating bite-sized, interactive courses using AI (with the ability to embed on websites).

Fun & Experimental Ideas

  • Custom Sound Generator – Like tryklack.com, but for different sounds (funny soundboards, niche noise generators, etc.). I actually paid for tryklack.com.

  • Single Source of Truth for Blogging – Post once (on GitHub, Notion, etc.), and the content syncs across platforms.

Take These & Build Something

If you’re still not sure what problem to solve, just pick one and try to build it. A lot of good ideas and problems to solve come from the issues and roadblocks you face while trying to build things. You don’t need a perfect idea—just start, and new opportunities will come up along the way.

There’s a mix of APIs, SaaS, and platform ideas here, so pick one, validate it, and see where it leads. Some might already have competition, but if a similar product is making money, it’s proof of demand.

I previously built and sold LectureKit, and I’m currently working on CaptureKit (a web scraping API), and I'm always writing ideas when I face new problems while building :)

If you had to build one of these, which would you pick?

Which one do you think is shit?

Do you have an idea of your own to share?
