CPOS

Captures competitive-programming problems and runs/submits them from VS Code or a terminal TUI.

Desktopfreeglobal

CPOS is a set of connected tools — a browser extension, a VS Code extension, and a terminal app — that automate the busywork of competitive programming. It captures a problem's samples from Codeforces, CSES, or AtCoder, creates a ready-to-edit solution file, runs tests locally, and submits through the user's own logged-in judge session. It's for competitive programmers who want to skip manual copy-pasting.
