Mmar – open-source, zero-dependancy, cross-platform HTTP tunneling
Hey HN! For the past couple of months, I've been working on and off on a cool project I'm excited to share. mmar (pronounced "ma-mar") is an open-source, zero dependency, cross platform and self-hostable HTTP tunnel built in Go. It allows you to easily expose your localhost to the world on a public URL. You can easily create an HTTP tunnel right away for free on a randomly generated subdomain on "*.mmar.dev" if you don't feel like self-hosting. This isn't something new, in fact there's quite a few of alternative HTTP tunneling tools out there. mmar is my attempt to optimize for a super easy…

In plain words
Mmar is an open-source HTTP tunneling tool built in Go that exposes local servers to the internet via public URLs. It requires no dependencies and runs cross-platform, offering free tunnels on randomly generated subdomains or self-hosting options. Designed for developers seeking simplicity, mmar provides an alternative to existing tunneling solutions with a focus on ease of use and straightforward implementation.

Pico: An open-source Ngrok alternative built for production traffic2024 · github.com · ▲244Pico is an open-source alternative to Ngrok. Unlike most other open-source tunnelling solutions, Pico is designed to serve production traffic and be simple to host (particularly on Kubernetes). Upstream services connect to Pico and register endpoints. Pico will then route requests for an endpoint to a registered upstream service via its outbound-only connection. This means you can expose your services without opening a public port. Pico runs as a cluster of nodes in order to be fault tolerant, scale horizontally and support zero downtime deployments. It is also easy to host, such as a…
Bor – Open-source policy management for Linux desktopsAug 2026 · getbor.dev · ▲197Hi HN! I've been working on Bor, an open-source system for centralized Linux desktop management. Bor consists of a lightweight Go agent and a central server. Policies are streamed to clients over mTLS/gRPC in real time—no polling—and currently support Firefox, Chrome, KDE, dconf, polkit and package management, with more coming. Version 0.8 introduces several new policy types - Thunderbird, Microsoft Edge for Business and FirewallD zones, along with a number of improvements and fixes. I'd love feedback on the architecture, policy model, and whether this is something you'd consider for…

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…
