DeepSeek

4.3 (312)

DeepSeek shook up the AI world by offering models that rival the best paid solutions, completely free of charge. Its conversational assistant particularly shines at programming and mathematical reasoning, thanks to the DeepThink mode that walks through its reasoning step by step before answering. Since April 2026, the service has been powered by DeepSeek V4, an open model capable of handling up to one million tokens of context.

Windsurf

4.4 (167)

Windsurf is an agentic IDE created by Codeium and now owned by Cognition (the maker of Devin), which rebranded it as Devin Desktop in June 2026. Its local agent, Cascade — now Devin Local — analyzes your entire project, plans changes, edits multiple files and runs commands to carry out development tasks end to end. It stands out for its deep understanding of large codebases (Fast Context, Codemaps) and free access to its in-house SWE-1.6 model.
