If you're looking for a SourceAI alternative, Kodezi is a good option. The tool uses AI to help with code completion, debugging and optimization across more than 30 programming languages. It also can generate documentation, translate code and run on a web interface. It's got a lot of bells and whistles, but it's also got a free tier and a Pro option for those who need more.
Another good option is Code Snippets AI, which uses multiple AI models to generate code and to refactor code you've written. It supports a broad range of programming languages and can generate code documentation, debug code and encrypt code so it's protected even if it's stored on an untrusted server. The service is updated based on user feedback and offers a free desktop app and Pro and Teams plans for more advanced features.
ZZZ Code AI is another option, particularly if you want a multilanguage coding assistant. It supports a variety of programming languages and can generate code, explain it, debug it and document it. It's free to use, but with character limits and daily limits on use, so it's good for casual use.
If you want a more integrated coding assistant, Codeium is a powerful tool that supports more than 70 programming languages and works with major IDEs. It can provide advanced code completion, AI-powered search and a chat interface that can generate code, refactor code and generate documentation. Codeium is geared for individuals and teams, with pricing tiers to accommodate different needs.
