Published on: June 12, 2025 | By: CodeToCareer
Why Sell Your Side Project?
You've built something awesome—a Python tool, ML model, data dashboard, or a full-blown SaaS. But instead of letting it collect digital dust, why not sell it? Whether you're pivoting, moving on, or just want to monetize your effort, there are marketplaces that help you connect with buyers who value data-driven projects.
What Can You Sell?
- AI/ML-powered web apps
- APIs, dashboards, or data visualization tools
- Scripts and automations
- Jupyter notebooks and research projects
- Mini SaaS solutions
- Open-source tools with monetizable features
10 Marketplaces to List Your Project
1. Flippa
A well-known marketplace for websites, SaaS products, and digital assets. Flippa offers valuation tools, escrow protection, and a broad buyer base.
2. IndieMaker
A niche platform for indie developers to buy/sell side projects, domains, and MVPs. It’s perfect for early-stage data-driven tools and solo products.
3. MicroAcquire (now Acquire.com)
Best for SaaS businesses and tools that already have traction or revenue. Great for data platforms or analytics dashboards.
4. SideProjectors
As the name suggests, it’s for side projects. It caters to makers looking to sell apps, scripts, or even unfinished ideas.
5. Code Canyon
Part of Envato Market, this is great for selling data science scripts, dashboards, and Python utilities. Best for plug-and-play code assets.
6. Gumroad
Simple and creator-friendly. Sell notebooks, AI templates, and digital guides. Perfect for tutorials or one-off scripts with an audience.
7. Product Hunt
Not exactly a marketplace but a powerful launchpad. Pair this with a Stripe or Gumroad link to drive visibility and direct sales.
8. BuyMySideProject
A lean, community-driven marketplace for devs who want to sell fast without much formality. Great for micro-tools and MVPs.
9. SaaSPlace
A newer player focused specifically on selling SaaS tools. If your data science side project is SaaS-ready, this is a good bet.
10. GitHub Sponsors + Self-hosted Shop
For open-source contributors, combine GitHub Sponsors with a self-hosted paywall or license model. Monetize directly without a middleman.
Tips for Selling Successfully
- Clean up your code: Buyers want well-documented, functional codebases.
- Showcase value: Add demo videos, explain how it solves a problem.
- Add metrics: Include downloads, user base, revenue, or traffic stats.
- Price fairly: Use tools like MicroAcquire's valuation calculator.
- Include support docs: Setup instructions and architecture diagrams help.
Conclusion
Your side project deserves more than being forgotten in a GitHub graveyard. Whether you're a student, data scientist, or indie hacker, these marketplaces open the door to turning your projects into passive income—or a valuable exit. Clean it, list it, and sell it. Your next buyer might be just a few clicks away.
