CoCalc, CodSpeed, and CrossFTP were grouped together by category tag, not by competing for the same buyer — they solve three unrelated problems. CoCalc is a…

Three different jobs, not three options
CoCalc is a collaborative computing and course-management platform, CodSpeed is a CI performance-testing service, and CrossFTP is a file-transfer client. There's no scenario where you'd genuinely choose between all three for the same task.

Pricing structures reflect who's paying
CoCalc scales cost with compute, storage, and the number of projects or students, which fits a classroom or lab budget. CodSpeed is a per-seat SaaS subscription typical of a dev-tool bought by an engineering org. CrossFTP sells a one-time perpetual license per computer, closer to classic desktop software pricing.

Only CrossFTP works fully offline
CrossFTP is a native Java desktop app you install and run locally to move files, with no requirement to be inside a browser or CI pipeline. CoCalc and CodSpeed are both cloud/SaaS-delivered and depend on an internet connection to function.
CrossFTP
Free entry points differ in generosity
CodSpeed's free tier covers up to 5 users and is unlimited for open-source projects, CoCalc offers a free tier before compute and storage upgrades kick in, and CrossFTP ships a fully free base version with paid Pro/Enterprise editions layered on top for scheduling and sync features.

No. CoCalc is a cloud computing and course-management platform for math, data science, and programming instruction, CodSpeed is a CI-integrated performance-benchmarking tool for engineering teams, and CrossFTP is a desktop file-transfer client for FTP/SFTP and cloud storage. They were grouped here by category tag rather than genuine overlap.
All three offer a free way in: CoCalc has a free tier before compute/storage upgrades, CodSpeed is free for up to 5 users and unlimited for open-source projects, and CrossFTP's base version is free indefinitely, with paid upgrades only needed for scheduling, sync, and multi-threaded transfers.
Yes. CoCalc is specifically built around real-time multi-user Jupyter, SageMath, Python, R, and LaTeX editing plus course-management tools, which is the exact use case CodSpeed and CrossFTP don't address.
No, they do unrelated jobs. CodSpeed detects performance regressions in code by running benchmarks inside CI pipelines, while CrossFTP physically moves files between machines, servers, and cloud storage buckets.
CodSpeed is the one built for CI/CD, integrating with GitHub Actions and other CI providers to report performance regressions directly on pull requests. CoCalc and CrossFTP have no CI/CD integration in their descriptions.
CrossFTP is the only one of the three built as a native cross-platform desktop application (Windows, macOS, Linux); CoCalc and CodSpeed are both cloud/SaaS products.
