Pony
Pony is an open-source, object-oriented, actor-model, capabilities-secure, high-performance programming language.
Status
Pony is still pre-1.0 and as such, semi-regularly introduces breaking changes. These changes are usually fairly easy to adapt to. Applications written in Pony are currently used in production environments.

- ✗ Unsupported — no support
- — Not applicable — combination doesn’t exist
On Windows, the minimum supported version is Windows 11 / Windows Server 2022
(build 20348). Pony’s networking uses an OS readiness API introduced in that
build; earlier versions, including Windows 10, are unsupported and a Pony binary
will not run on them.
On Linux, the minimum supported version is kernel 5.3. Pony’s process
support detects a child’s exit with pidfd_open, a system call added in that
release; on an older kernel, starting a process returns an error. Earlier
kernels are unsupported.
Build prerequisites
The standard library’s net package requires an SSL/TLS development library at build time — OpenSSL (1.1.x, 3.0.x, or 4.0.x) or LibreSSL. CMake auto-detects the installed version and passes the right flag to ponyc; the build fails at configure time if no supported SSL library is found. See BUILD.md for per-distribution package names.
