Replit is an all-in-one browser IDE to build, host, and ship apps with AI assistance across many languages. CodeSandbox is a fast online dev environment focused on web prototyping and sharing. Replit wins on breadth and shipping; CodeSandbox wins on fast web prototyping.
Pick Replit if you want an all-in-one browser IDE to build, host, and ship apps across many languages with AI help.
Pick CodeSandbox if you want fast, shareable sandboxes for web prototyping, examples, and reviews.
Replit and CodeSandbox are both browser-based development environments, but they emphasize different workflows. Replit is broad and all-in-one: it supports many languages, includes hosting and deployment, and bakes in AI assistance, making it a place to build and ship complete apps from the browser. CodeSandbox is web-focused and fast, optimized for quickly spinning up sandboxes to prototype front-end projects, share examples, and review code.
On price, both have free tiers; Replit Core starts around $20 a month and CodeSandbox paid plans around $12. The choice is mostly an all-in-one build-and-ship IDE across languages (Replit) versus fast web prototyping and sharing (CodeSandbox).

Things neither product's marketing page leads with.
Replit is broader and better for shipping complete apps, but it can be heavier than a quick sandbox.
CodeSandbox is faster for web prototyping and sharing, but it is more web-focused and less of an all-in-one ship-it platform.
For building and shipping Replit wins; for quick web prototypes CodeSandbox wins.
