Which is better for open-source developers?
Codeium is significantly better for open-source work. It offers unlimited free completions (vs Supermaven's 50/month), is trained on permissively-licensed code avoiding GPL concerns, and supports more editors like Vim and Emacs commonly used in open-source communities. The unlimited free tier means contributors can use it indefinitely without hitting limits.
Supermaven is substantially better for large codebases due to its 300K token context window (4.6x larger than Codeium's 64K). This allows it to understand entire files, multiple related files, and complex architectural patterns in a single completion request. For monorepos and enterprise projects exceeding 50KB per file, Supermaven's context advantage is decisive.
What's the cost difference for professional developers?
Codeium Pro is $12/month while Supermaven Pro is $10/month, a $24/year difference. However, Codeium's free tier with unlimited completions means many individual developers never need to pay, whereas Supermaven's 50-completion limit forces most paid upgrades. For teams of 10 developers, Codeium could save $240/year if free tiers suffice, or cost $1,440/year for full team coverage vs Supermaven's $1,200/year.
Codeium supports more IDEs (6 vs 4), including Vim, Neovim, Emacs, and Visual Studio. Supermaven excels at VS Code and Cursor integration with tighter IDE awareness. If you use primarily VS Code or JetBrains, both are equivalent; if you use Vim, Emacs, or Visual Studio, Codeium is the only viable option.
How much faster is Supermaven's code completion?
Supermaven completes code 2.5-3x faster than Codeium (175ms vs 450ms average). This ~275ms difference becomes noticeable during rapid coding sessions—Supermaven feels near-instantaneous while Codeium has a brief but perceptible delay. For developers writing 100+ completions daily, Supermaven saves 30-45 minutes of accumulated waiting time per week.
