Usque – Open-Source Cloudflare Warp Masque Client
I was surprised to discover there isn't an open-source initiative for a Cloudflare Warp client that fully supports their MASQUE protocol. MASQUE has the potential to revolutionize traditional VPNs, even in self-hosted environments, but there’s been a gap in the ecosystem. I built a proof-of-concept client using the amazing quic-go library that not only integrates their (for some reason) non-rfc compliant MASQUE but also supports multiple modes of operation. This includes full support for any IP traffic and a proxy mode, making it hopefully flexible. I'd love to hear feedback from the…

In plain words
Usque is an open-source client for Cloudflare Warp that implements the MASQUE protocol, built using the quic-go library. It supports multiple modes of operation including full IP traffic handling and proxy mode, offering an alternative to traditional VPNs in self-hosted environments. Designed for developers and technical users, it fills a gap in the open-source ecosystem by providing flexible protocol support that extends beyond standard implementations.

Octelium – FOSS Alternative to Teleport, Cloudflare, Tailscale, Ngrok2025 · github.com · ▲358I 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…
Open source alternative to Perplexity Comet2025 · browseros.com · ▲291Hey HN, we're a YC startup building an open-source, privacy-first alternative to Perplexity Comet. No invite system unlike bunch of others – you can download it today from our website or GitHub: https://github.com/browseros-ai/BrowserOS --- Why bother building an alternative? We believe browsers will become the new operating systems, where we offload much bunch of our work to AI agents. But these agents will have access to all your sensitive data – emails, docs, on top of your browser history. Open-source, privacy-first alternatives need to exist. We're not a search or ad…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
