Pony
August 13, 2026 · View on GitHub
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.

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.
