Reviewers see Replit as a fast, accessible way to build and test apps in the browser, especially for beginners, rapid prototyping, and collaborative work. Several praise its simple setup, decent UI, and ability to help non-developers get started quickly. But the criticism is sharp and specific: buggy AI edits, regressions that still consume credits, confusing interface choices, weak testing and environment separation, database connection issues, and growing frustration over paid limits and refund policies. For production use, some reviewers say reliability and billing trust remain serious concerns.
