Best free AI tools for indie devs
Shipping on a shoestring? Every tool on this page is either completely free or has a free tier, according to the ToolDrop directory. Most of the fully free picks are open source: OpenCode for coding in your terminal, Stable Diffusion for images run locally, plus LangChain, Haystack, Semantic Kernel and the Vercel AI SDK for building AI features into your own game or app. Epherem is free during early access and scans AI-built apps for security problems. After those come the freemium favourites, so you can try before you pay. They include Cursor and Replit for code, Pixel Lab and Leonardo AI for art, Suno and Udio for music, and ElevenLabs for voice. Free tiers change often, so check the limits on each tool's site.
Prices and details come from the ToolDrop directory and are as listed by each vendor. They can change, so check each tool's site.
