Octelium – FOSS Alternative to Teleport, Cloudflare, Tailscale, Ngrok▲358
I have been working on Octelium for quite a few years now but it was open sourced only by late May 2025. Octelium, as described more in detail in the repo's README, is simply an open source, self-hosted, unified platform for zero trust resource access that is primarily meant to be a modern alternative to corporate VPNs and remote access tools. It can operate as a remote access/corporate VPN (i.e. alternative to Twingate, Tailscale, OpenVPN Access Server, etc...), a ZTNA/BeyondCorp platform (i.e. alterntive to Cloudflare Access, Teleport, Google BeyondCorp, etc...), and it can also…

Zerobox – Sandbox any command with file, network, credential controls▲141
I'm excited to introduce Zerobox, a cross-platform, single binary process sandboxing CLI written in Rust. It uses the sandboxing crates from the OpenAI Codex repo and adds additional functionalities like secret injection, SDK, etc. Watch the demo: https://www.youtube.com/watch?v=wZiPm9BOPCg Zerobox follows the same sandboxing policy as Deno which is deny by default. The only operation that the command can run is reading files, all writes and network I/O are blocked by default. No VMs, no Docker, no remote servers. Want to block reads to /etc? zerobox…

Weron – A Peer-to-Peer VPN Based on WebRTC Written in Go▲204
Hey HN! I just released weron, a P2P VPN that uses WebRTC for transport which I've been working on for the last couple of months. It can create both layer 2/Ethernet and layer 3/IP overlay networks, and the underlying transport layer can be easily embedded to write your own P2P apps with Go. Compared to for example Tailscale, WireGuard and ZeroTier, its much harder to block on a network level and also significantly easier to set up, while not sacrifing much performance. I'd love to get your feedback :)
