Please see the newest tasks introduced into our library in March 2026:
We're excited to announce that Task Library now supports Next.js and LangChain — two technologies that were explicitly asked for and that are increasingly important in modern hiring.
All newly released Codility tasks are immediately and thoroughly tested against generative AI tools. We also recommend using the “New Tasks” filter to find the latest additions easily.

We’re adding a pair of Starter-level Tic-Tac-Toe tasks to strengthen the entry-level end of the library in both Coding and Algo:
