[Other] The NextJS boilerplate that all you need to reach 1K+ MRR Hey Builders 👏 From the last 1 year, I’ve been building and shipping products, and every time I had to repeat the same boring tasks. Setting up the database, auth, payments, SEO, emails, analytics. All of this took more time than actually building the product. So I built BuildFast, a production-ready Next.js boilerplate with auth, payments, database, emails, UI, SEO, and analytics already set up. It’s built to help you ship faster and make your first dollar online. Thankyou

Built with TypeScript, zero dependencies, and full async support — making session security observable, extensible, and easy to manage.

[Other] Show HN: Deploy backends without the hassle. An Open source alternative

[Other] Show HN: A small programming language where everything is a value This is a hobby project of mine that I started a few years ago to learn about programming language implementation. It was created 95% without AI, although a few recent commits include code from Gemini CLI.<p>I started out following Crafting Interpreters, but gradually branched off that until I had almost nothing left in common.<p>Tech stack: Rust, Cranelift (JIT compilation), LALRPOP (parser).

[CLI Tool] Show HN: Bucket – Encrypted file sharing for people who live in the terminal I built this because I am perpetually drowning in file transfer hell.<p>As a systems engineer, I am constantly moving massive files. Whether it&#x27;s getting new releases of custom ISOs to clients, downloading entire filesystems to spin up clones, or uploading massive support packages to L3.<p>I always have to get something to somebody. Usually, it&#x27;s something large that lives on a headless server. I can&#x27;t tell you how many times I&#x27;ve modified my &#x27;clone&#x27; script to tar most of a filesystem over ssh (&quot;hello --exclude, my old friend...&quot;) just to get 10GB that someone will need for two days.<p>Tedious is an understatement.<p>And the truth is, whatever I am sending, it is ephemeral. I download it, I upload it, I delete it. They download it only to delete soon after.<p>I kept wondering - why isn&#x27;t there a simpler tool that works where I spend 90% of my time -- the terminal? I wanted something that I could install quickly on whatever server I was currently connected to, and run a simple command to push to the cloud.<p>Enter Bucket – a secure, encrypted file sharing platform that works the way I do. I upload from the CLI, share with a link and unique secret, done. No browser required (unless you want it). The people you&#x27;re sharing with can simply click the link you share to download, no need for them to make an account (unless they want it).<p>What makes it different:<p>- CLI-first: Built for terminal workflows first, web UI second<p>- Encryption: End-to-end AES-256 encryption. We never see your files or your secrets. The secret generated during a push is required for the pull, keeping your data private even from us. If you lose the secret, you can&#x27;t access the file.<p>- Simple scalability: Free tier for trying it out, plans up to 250GB for serious use, enterprise coming soon.<p>- File retention: Bucket is designed for ephemeral storage. Upload things that people need <i>now</i>. Free tier keeps files for 3 days (email notifications are sent to you before they are deleted, in case you need to upload again)<p>Colleagues I have introduced this to tell me they use it every day. I know that I do.<p>Free tier gives you 3 GB to try it out - enough for most one-off transfers.<p>Here&#x27;s the workflow:<p><pre><code> $ bucket push api.bin Verifying upload... Upload complete! bID: bkdf1e848ea23e bURL: api.bucketlabs.org&#x2F;d&#x2F;bkdf1e848ea23e Secret: 9b1e15167403a88cadb7d0f4d2890856 Expires: 2026-01-28T03:15:18.277988Z </code></pre> Now you have a link for your browser-dwellers to simply click, paste the Secret and download. (go ahead, try on the link above to download the readme.md)<p>... but if the person you&#x27;re sharing with has bucket installed they simply run:<p><pre><code> $ bucket pull bkdf1e848ea23e Enter secret: ⠇ Downloading... Downloaded: api.bin </code></pre> Check your file:<p><pre><code> $ bucket list ID Filename Size Expires ---------------------------------------------------------------------- bkdf1e848ea23e api.bin 204.2 MB 2026-01-28T03:15:18.277988Z $ bucket account Account Info ------------ Subscription: free Used: 204.2 MB Quota: 3.00 GB To increase storage limits, visit: https:&#x2F;&#x2F;bucketlabs.org&#x2F;auth </code></pre> Everyone you needed to pull have the file? Go ahead and delete:<p><pre><code> $ bucket del bkdf1e848ea23e Deleted: bkdf1e848ea23e </code></pre> Built in Go. Single static binary, works anywhere. Download at bucketlabs.org

[DevOps] Show HN: Netfence – Like Envoy for eBPF Filters To power the firewalling for our agents so that they couldn&#x27;t contact arbitrary services, I build netfence. It&#x27;s like Envoy but for eBPF filters.<p>It allows you to define different DNS-based rules that are resolved in a local daemon to IPs, then pushed to the eBPF filter to allow traffic. By doing it this way, we can still allow DNS-defined rules, but prevent contacting random IPs.<p>There&#x27;s also no network performance penalty, since it&#x27;s just DNS lookups and eBPF filters referencing memory.<p>It also means you don&#x27;t have to tamper with the base image, which the agent could potentially manipulate to remove rules (unless you prevent root maybe).<p>It automatically manages the lifecycle of eBPF filters on cgroups and interfaces, so it works well for both containers and micro VMs (like Firecracker).<p>You implement a control plane, just like Envoy xDS, which you can manage the rules of each cgroup&#x2F;interface. You can even manage DNS through the control plane to dynamically resolve records (which is helpful as a normal DNS server doesn&#x27;t know which interface&#x2F;cgroup a request might be coming from).<p>We specifically use this to allow our agents to only contact S3, pip, apt, and npm.

[Other] Xmake: A cross-platform build utility based on Lua

[Other] Show HN: Sightline – Shodan-style search for real-world infra using OSM Data Hi HN,<p>I built *Sightline*, a Shodan-style search engine for *physical-world infrastructure*.<p>Shodan makes it easy to explore exposed internet services. Sightline applies the same idea to the real world, using OpenStreetMap as the data source.<p>You can search things like:<p>* “telecom towers in karnataka” * “power plants near mumbai” * “data centers in paris france”<p>or use structured queries:<p>* `type:telecom operator:airtel region:karnataka` * `type:data_center operator:google`<p>Sightline:<p>* uses Overpass API for querying OSM features * uses Nominatim for resolving countries, regions, and cities * avoids hardcoded geography * uses deterministic, rule-based parsing (no AI inference)<p>Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;ni5arga&#x2F;sightline" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;ni5arga&#x2F;sightline</a> Try it out: <a href="https:&#x2F;&#x2F;sightline-maps.vercel.app" rel="nofollow">https:&#x2F;&#x2F;sightline-maps.vercel.app</a>

[Other] a stateless, pure TypeScript search engine for Quranic text. Quran Search Engine is a stateless, pure TypeScript search engine designed for Quranic text. It offers advanced features such as Arabic normalization, exact text search, lemma and root matching through morphology and word maps, and UI-agnostic highlight ranges. Unlike many Quran search solutions, this engine is not tightly coupled to a UI, is fully client-side or server-side, and is both stateless and deterministic. It is TypeScript-first and strongly typed.
