Code::Blocks vs Replit

Code::Blocks is a free IDE for C, C++ and Fortran on Linux, macOS and Windows. Its editor provides syntax highlighting, code folding, tabs, code completion, a class browser, and smart indent. A custom build system supports parallel builds, multi-target projects, workspaces, and inter-project dependencies. Listed compiler options include GCC, MSVC++, clang, Digital Mars, Borland C++ 5.5, and Open Watcom. The debugger interfaces with GNU GDB and also supports MS CDB, which the site describes as not fully featured. Code::Blocks imports MSVC projects and workspaces, although assembly code is not supported in those imports, and it imports Dev-C++ projects. A plugin framework allows added functionality through installed or written plugins; some are included in official releases and others are maintained externally. The software uses GNU GPL version 3, while its SDK uses GNU LGPL version 3, allowing closed-source plugins to link against it. Documentation is provided through a manual, wiki, and forums.

Replit is a software creation platform where users can describe applications in natural language and refine them with an AI agent. The agent works through chat, tests and revises code, and can use a browser to produce reports and address issues. Its cloud development environment supports coding and collaboration in a browser, with automatic package installation and built-in authentication, database, hosting, and monitoring. Replit supports websites, mobile projects, designs, slides, animations, data visualizations, 3D, games, documents, and spreadsheets, with more than 100 integrations. The free Starter plan includes daily usage, but limits publishing to one live project and running one background task at a time. Replit Core costs $18 per month billed annually, and Pro costs $90 per month billed annually. Pro supports up to 15 collaborators and 50 viewers, and includes database rollback for up to 28 days. Replit is available on Android, iOS, Linux, macOS, Windows, and web. Its mobile apps support building, sharing, and publishing web apps; native iOS development uses the web version with Expo Go previews.
