Rextester is an online code compilation and execution tool. Its homepage highlights “compile c# online,” but in practice it supports a wide range of languages. Users can choose a language in the browser, edit code, configure input and compiler arguments, and run it online. It also offers a RESTful API, making it suitable for embedding remote code execution into teaching platforms, practice systems, judging tools, or internal utilities.
According to the page content, Rextester supports many languages, including C#, F#, Java, Python/Python 3, C/C++, PHP, Go, Scala, Node.js, Rust, Kotlin, Bash, Elixir, Erlang, Fortran, and Clojure. It also provides database-related options for MySQL, PostgreSQL, Oracle, SQL Server, and more. The API is called via POST JSON, with parameters such as LanguageChoice, Program, Input, CompilerArgs, and ApiKey. Responses include Result, Warnings, Errors, and Stats; for Octave use cases, it can also return a list of base64-encoded PNG files. Overall, the API model is straightforward and well suited for quick integration.
The API uses a subscription model, tiered by daily request volume: €8/month for 1k requests/day, €15/month for 5k requests/day, €30/month for 15k requests/day, €60/month for 50k requests/day, and €120/month for 150k requests/day. All plans include a 7-day free trial and can be canceled. The documentation provides request examples, response examples, parameter explanations, and a list of language IDs, which is sufficient for basic integration. However, we did not find details on error codes, rate limiting, timeouts, authentication specifics, sandbox isolation policies, or SLA. These should be validated independently before production use.
The main advantages are broad language coverage, a simple API, response data that includes warnings and runtime statistics, and clearly defined pricing tiers. The drawbacks are that the page does not disclose whether it is open source or supports self-hosting, nor does it mention SDKs, IDE plugins, or a third-party ecosystem. Support channels appear to be limited to Patreon, with insufficient information about enterprise support. Rextester is a good fit for individual developers, programming education, online practice platforms, and tool-based products that need low-cost code execution capabilities.
The page does not provide information about access from mainland China, supported payment methods, or node locations, so availability is unknown. If launching a user-facing service in China, it is recommended to test network connectivity, API latency, payment feasibility, and peak-hour stability in advance. Alternatives to compare include Compiler Explorer, JDoodle, OnlineGDB, Replit, and Paiza.IO.
