I Spent Years Building a FOSS Unified Zero Trust Secure Access Platform
Hello HN, I've been working solo on Octelium for the past 5+ years now, (yes, you just read that correctly :|) along with a couple more sub-projects that will hopefully be released soon and I'd love to get some honest opinions from you. Octelium 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 is built to be generic enough to not only operate as a ZTNA/BeyondCorp platform (i.e. alternative to Cloudflare Zero Trust, Google BeyondCorp, Zscaler Private…
What it does
In the maker’s words, at launch
Hello HN, I've been working solo on Octelium for the past 5+ years now, (yes, you just read that correctly :|) along with a couple more sub-projects that will hopefully be released soon and I'd love to get some honest opinions from you. Octelium 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 is built to be generic enough to not only operate as a ZTNA/BeyondCorp platform (i.e. alternative to Cloudflare Zero Trust, Google BeyondCorp, Zscaler Private Access, Teleport, etc...), a zero-config remote access VPN (i.e. alternative to OpenVPN Access Server, Twingate, Tailscale, etc...), a scalable infrastructure for secure tunnels (i.e. alternative to ngrok), but also as an API gateway, an AI gateway, a secure infrastructure for MCP gateways and A2A architectures, a PaaS-like platform for secure as well as anonymous hosting and deployment for containerized applications, a Kubernetes gateway/ingress/load balancer and even as an infrastructure for your own homelab. Octelium provides a scalable zero trust architecture (ZTA) for identity-based, application-layer (L7) aware secret-less secure access, via both private client-based access over WireGuard/QUIC tunnels as well as public clientless access (i.e. BeyondCorp), for users, both humans and workloads, to any private/internal resource behind NAT in any environment as well as to publicly protected resources such as SaaS APIs and databases via context-aware access control on a per-request basis through policy-as-code. I'd like to point out that this is not an MVP, as I said earlier I've been working on this project solely for way too many years now. The status of the project is basically public beta or simply v1.0 with bugs (hopefully nothing too embarrassing). The APIs have been stabilized, the architecture and almost all features have been stabilized too. Basically the only thing that keeps it from being v1.0 is the lack of testing in production (for example, most of my own usage is on Linux machines and containers, as opposed to Windows or Mac) but hopefully that will improve soon. Secondly, Octelium is not a yet another crippled freemium product with an """open source""" label that's designed to force you to buy a separate fully functional SaaS version of it. Octelium has no SaaS offerings nor does it require some paid cloud-based control plane. In other words, Octelium is truly meant for self-hosting. Finally, I am not backed by VC and so far this has been simply a one-man show even though I'd like to believe that I did put enough effort to produce a better overall quality before daring to publicly release it than that of a typical one-man project considering the project's atypical size and nature.

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…
- OAOctosphere, a tool to decentralise scientific publishingFeb 2026 · octosphere.social · ▲64
Hey HN! I went to an ATProto meetup last week, and as a burnt-out semi-academic who hates academic publishing, I thought there might be a cool opportunity to build on Octopus (https://www.octopus.ac/), so I got a bit excited over the weekend and built Octosphere. Hopefully some of you find it interesting! Blog post here: https://andreasthinks.me/posts/octosphere/octosphere.html

Hi HN, We (myself, Adhyyan1252 and yush_g) are undergrad students that hacked out this side project last month during Hack Lodge[1] (the ideas and many of the underlying circuits for which came from the 0xPARC community[2])! We’re extremely excited to share this new primitive. Besides the technical challenges building this project that folks here would find interesting (fixing the ZK proof compiler, modifying nodeJS V8 params etc.), we think this is a very novel use case for ZK tech, and ECDSA inside ZK-SNARKs is a starting point that unlocks many other ideas! :D A summarized version of our…
- IMI made a privacy-first minimalist Backblaze2022 · blobbackup.com · ▲236
Creator here. I was looking for something as simple as Backblaze Personal [1] but privacy focused and open source. This is my attempt to build that. Uses PyQt6 [2] for the GUI and Pyinstaller [3] for creating the platform specific binaries. The backup engine under the hood is Restic [4]. The server code is written in Laravel [5]. All the code is on GitHub [6]. I actually really like Backblaze (even use B2 for this offering behind the scenes) so this isn't meant to throw shade their way. Just wanted a private open source alternative. Something like Bitwarden but for backups. [1]…

- POPangolin: Open-source identity-based VPN (Twingate/Zscaler alternative)Feb 2026 · github.com · ▲81
Pangolin (https://github.com/fosrl/pangolin) is an open-source tool for identity-based remote access to internal resources - an alternative to Cloudflare ZTNA, Zscaler, and Twingate. It’s different than existing approaches: mesh VPNs (Tailscale, ZeroTier, etc.) create flat overlay networks where ACL and IP space management becomes complex at scale and every device can talk to every other device, while corporate ZTNA solutions (Zscaler, Cato, Netskope etc.) are closed-source and add latency by forcing traffic through a central server. Pangolin takes a resource-centric…
