Why I'm Closing the Source Code of Canario Terminal
Closing Canario Terminal source code

Raphael Amorim, creator of Rio and Canario, explains his decision to close the source of Canario, a terminal he built for agentic coding. He cites the hidden costs of open source maintenance—issues, PRs, and demands—exacerbated by AI-generated spam. He clarifies Canario has no telemetry, and the code remains available in older Rio versions. He will continue maintaining Rio, but Canario will be developed at his own pace.
People underestimate what open source costs from the maintainer side. It’s not just writing code. It’s issues, pull requests, discussions, people demanding things from you for free.
