Visitcvc5 vs HOL4
What both publish
| Fact | cvc5 | HOL4 |
|---|---|---|
| Integrations | The project lists applications using cvc5, including Kind 2 and QMaxUSE as backend solvers, and TRLC through PyVCG for proving absence of runtime errors. | The maker documents editor support for Emacs and Vim. |
| Purpose | cvc5 is an efficient open-source automatic theorem prover for satisfiability modulo theories problems. | HOL4 is a proof assistant for higher-order logic and a programming environment for proving theorems and implementing proof tools. |
| Support | The project directs bug reports to its GitHub issue tracker and questions, feature requests, and contributions to GitHub Discussions. | The community offers help through a mailing list and Zulip chat, while bug reports and feature suggestions go to GitHub issues. |

Pick cvc5 if…
It suits researchers and developers working with theorem proving, SMT problems, or syntax-guided synthesis. It can be used directly or integrated through its programming APIs.
Pick HOL4 if…
HOL4 suits users working on higher-order logic theorem proving, proof tools, or property checking. It may also suit projects that need to connect proof work with external SMT or BDD tools.
