Explore side projects by category and technology stack:
SideProjectors is a marketplace and community platform where developers can buy, sell, and showcase their side projects. It's designed for entrepreneurs, developers, and creators who want to monetize their side projects or find collaborators for their ideas.
SideProjectors allows developers to submit their side projects in three ways: selling established projects with proven revenue, seeking co-founders for new ventures, or showcasing innovative projects to the community. All projects go through a review process to ensure quality and authenticity.
You can find a wide variety of side projects including web applications, mobile apps, SaaS products, e-commerce solutions, AI/ML projects, blockchain applications, developer tools, and games. Projects span all major technology stacks and programming languages.
To sell your project, create an account, submit your project with detailed information including revenue data, user metrics, technology stack, and pricing. Our team reviews submissions to ensure quality before approval. Include screenshots, demos, and clear documentation to increase your chances of approval.
Include detailed project descriptions, technology stack, monthly revenue and visitor data, screenshots or demos, source code access, documentation, and your reason for selling. The more transparent and detailed your submission, the more attractive it will be to potential buyers.
Submit your project as a "co-founder" listing with details about your idea, required skills, your background, and what you're looking for in a partner. Be specific about the time commitment, equity split, and project goals to attract the right collaborators.
Popular technologies include React, Vue.js, Angular for frontend; Node.js, Python, Ruby on Rails, Laravel for backend; React Native, Flutter for mobile; and cloud platforms like AWS, Vercel, and Heroku. AI/ML projects using Python, TensorFlow, and PyTorch are also growing in popularity.
Consider factors like monthly revenue, user base size, development time invested, market demand, and technology stack. A common approach is 2-3x annual revenue for established projects, or based on development hours and market value for newer projects. Research similar projects on the platform for reference.
SideProjectors offers both free and premium features. Basic project submissions and browsing are free. Premium features may include enhanced visibility, priority support, and advanced analytics. Check our pricing page for current fee structure and membership options.
Provide complete information, include working demos or screenshots, be transparent about revenue and metrics, use clear and professional descriptions, and ensure your project is fully functional. Projects with proven track records and detailed documentation have higher approval rates.
Yes! Many buyers purchase projects to continue development, add new features, or pivot the business model. When buying, ensure you receive all necessary assets including source code, documentation, domain access, and any third-party service accounts.
Successful listings have clear value propositions, proven metrics, professional presentation, detailed documentation, and transparent communication. Include screenshots, demos, revenue data, and be responsive to potential buyers' questions. Honesty about challenges and opportunities builds trust.
