Coq Dependent Type Projects
A function definition package for CoqProject mention: Learn coq or agda before diving into idris2? | reddit.com/r/dependent_types | 2021-05-02
I'd say Agda is more similar to Idris than Coq. Coq has a different syntax and isn't as good for programming with dependent types as Agda and Idris (Agda and Idris both put a huge emphasis on dependent pattern matching, something that Coq only recently gained support for through the Equations package).
