In their own words
PyCharm
PyCharm is an IDE for web, data, and AI/ML professionals, with tools for Python development. It provides code completion, PEP 8 checks, inspections, and refactoring, alongside debugging and testing. The IDE includes an integrated terminal, package managers, Docker integration, and support for Pipenv, conda, virtualenv, and Poetry. Version control includes Git, GitHub, GitLab, Subversion, Mercurial, and Perforce; database tools cover MySQL, SQL Server, PostgreSQL, Oracle, Redis, and other providers. Local AI code completion can run local LLMs without sending code over the internet. Remote development supports several listed services, and remote connections use end-to-end TLS 1.3 with SSH security and host-fingerprint verification. PyCharm runs on Linux, macOS, and Windows. Its free plan costs nothing and includes one month of Pro. The listed Pro plan costs $200 a year, billed per user per year. PyCharm Ultimate can be evaluated free for 30 days before purchase and license activation are required.
Python Online
Python Online is a browser-based, container-backed Python IDE for writing, running, and hosting applications. Code executes in isolated Linux containers, while the Monaco editor provides IntelliSense, multi-cursor editing, flexible pane layouts, and Ruff linting. Users can search PyPI and install packages in isolated project environments. Hosted Flask, FastAPI, Django, and Streamlit applications receive pythononline.app subdomains with SSL. Registered accounts can schedule one daily headless task limited to 60 seconds. A persistent Python REPL supports interactive work, and matplotlib or plotly plots can appear in the output console. The free registered account costs nothing and includes up to three projects, 512 MB cloud storage, one hibernating web app, one daily task, and proxy-based outbound access. Guest projects remain in browser memory and lack internet, hosting, and scheduling. Projects export as ZIP archives.
