Google Colab vs OneCompiler

Google Colab lets users write and run Python in a browser without configuring a local environment, with access to GPUs and notebook sharing. Its hosted Jupyter notebooks combine executable code with rich text, images, HTML, and LaTeX. Data can come from Google Drive, spreadsheets, GitHub, and other sources, with Google Cloud Storage, Sheets, and BigQuery resources listed for integration. Colab AI can generate or transform code, explain Python libraries, suggest fixes, and perform multi-step data-analysis workflows. By default, it does not access Drive files or user secrets, though it can generate code to access them when explicitly requested. Google says generative-AI features collect prompts, related code, outputs, usage information, and feedback; human reviewers may process that data for up to 18 months. Free notebooks can run for at most 12 hours, depending on availability and usage. Pro+ supports continuous execution up to 24 hours when enough compute units are available. Colab also has a Visual Studio Code extension and a beta, allowlist-gated API. Paid plans start at 8.33 USD/user/mo (annual).

OneCompiler is an online environment for writing, running and sharing code, available on the web and Android. It supports more than 60 programming languages, plus web technologies and databases such as MySQL, MongoDB and PostgreSQL. Its free plan includes unlimited code executions and 20 AI credits per day. OneCompiler Studio runs Visual Studio Code in a browser with a Linux container, terminal, package manager, debugger and persistent workspaces; supported projects can be deployed to a live URL and shared by link. The service also offers code execution APIs and embeddable editor, challenge, Studio and AI interview capabilities. Its LMS integration uses a JWT token and requires an email address and name to create or sign in a user. OneCompiler supports private projects, real-time collaboration, public sharing and custom domains. The company says it helps over 12.8 million developers worldwide and describes use by LLM companies, colleges, EdTech providers and interview companies. Organizations are being retired; new ones cannot be created and no further features are planned for them.
