# 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.
## Supported platforms
| OS \ CPU | `amd64` | `arm64` | `arm32` | `riscv64` |
|---|---|---|---|---|
| **Linux** | ✅ Released | ✅ Released | 🔧 Best-effort | 🧪 Tested |
| **macOS** | ✅ Released | ✅ Released | — | — |
| **Windows** | ✅ Released | ✅ Released | — | — |
| **FreeBSD** | 🧪 Tested | ✗ Unsupported | — | — |
| **OpenBSD** | 🧪 Tested | ✗ Unsupported | — | — |
| **DragonFly BSD** | 🧪 Tested | — | — | — |
* ✅ **Released** — official prebuilt binaries; also tested in CI
* 🧪 **Tested** — tested in CI; build from source (no prebuilt binary)
* 🔧 **Best-effort** — not in CI; built from source and tested periodically on real hardware
* ✗ **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](BUILD.md) for per-distribution package names.
