Preferred over Rust for safety
A formally verifiable Ada language whose compiler proves absence of runtime errors and correctness, recommended for safety-critical code; the common caveats are higher development cost and heavy proof ceremony.
Simple and approachable to learn
Recommended as a simple, approachable language for proving code correct, with executable output. Critics question its developer experience and production use.
Useful and impressive in practice
Lets Rust programmers prove code correct against specifications kept beside the implementation. Most common caveat: its verus! macro wrapping all code unsettles rust-analyzer and tooling.

Select a column heading to sort. Approval share is recommenders out of everyone who gave an opinion; the tick on each bar marks the 2 to 1 line the badge needs. Months counts the months, out of 13, in which someone recommended it.
How we rank

The badge goes to verification languages that at least 10 people recommend, with recommenders outnumbering critics at least 2 to 1, recommended in at least 4 of the 13 months.
