Is Codium AI worth the price?

78/100

Codium AI's pricing is fair and generous for individual developers with a free tier offering 250 credits/month, but the Teams plan at $19/user/month is a strong value given its test generation and PR-Agent features.

However, heavy users may find the 2,500 credit cap limiting, and Enterprise custom pricing could be steep. Best for small to medium teams looking for AI-driven test automation.

How Codium AI Compares to Competitors

Compared to Diffblue, which focuses on enterprise test generation at higher prices, Codium offers a more accessible free tier and lower team cost. GitHub Copilot provides broader code completion but lacks dedicated test generation, making Codium a better fit for teams prioritizing automated testing over general AI assistance.

How Codium AI's pricing compares

At $19/mo, Codium AI is mid-range of its 5 direct competitors ($10 to $49.92/mo across the set).
