Show HN: See the carbon impact of your cloud as you code https://ift.tt/WDP3rOj

Show HN: See the carbon impact of your cloud as you code Hey folks, I’m Hassan, one of the co-founders of Infracost ( https://ift.tt/PBjvO3x ). Infracost helps engineers see and reduce the cloud cost of each infrastructure change before they merge their code. The way Infracost works is we gather pricing data from Amazon Web Services, Microsoft Azure and Google Cloud. What we call a ‘Pricing Service’, which now holds around 9 million live price points (!!). Then we map these prices to infrastructure code. Once the mapping is done, it enables us to show the cost impact of a code change before it is merged, directly in GitHub, GitLab etc. Kind of like a checkout-screen for cloud infrastructure. We’ve been building since 2020 (we were part of YC W21 batch), and iterating on the product, building out a team etc. However, back in 2020 one of our users asked if we can also show the carbon impact alongside costs. It has been itching my brain since then. The biggest challenge has always been th...

Show HN: APIsec MCP Audit – Audit what your AI agents can access https://ift.tt/nfapNBC

Show HN: APIsec MCP Audit – Audit what your AI agents can access Hi HN — I built APIsec MCP Audit, an open source tool to audit Model Context Protocol (MCP) configurations used by AI agents. Developers are connecting Claude, Cursor, and other assistants to APIs, databases, and internal systems via MCP. These configs grant agents real permissions, often without security oversight. MCP Audit scans MCP configs and surfaces: - Exposed credentials (keys, tokens, database URLs) - What APIs or tools an agent can call - High-risk capabilities (shell access, filesystem access, unverified sources) It can also export results as a CycloneDX AI-BOM for governance and compliance. Two ways to try it: - CLI: pip install mcp-audit - Web demo: https://apisec-inc.github.io/mcp-audit/ Repo: https://ift.tt/syUS6mu We're a security company (APIsec) and built this after repeatedly finding secrets and over-permissioned agent configs during assessments. Would appreciate feedback — especially on risk scorin...

Show HN: Subth.ink – write something and see how many others wrote the same https://ift.tt/6d71vJC

Show HN: Subth.ink – write something and see how many others wrote the same Hey HN, this is a small Haskell learning project that I wanted to share. It's just a website where you can see how many people write the exact same text as you (thought it was a fun idea). It's built using Scotty, SQLite, Redis and Caddy. Currently it's running in a small DigitalOcean droplet (1 Gb RAM). Using Haskell for web development (specifically with Scotty) was slightly easier than I thought, but still a relatively hard task compared to other languages. One of my main friction points was Haskell's multiple string-like types: String, Text (& lazy), ByteString (& lazy), and each library choosing to consume a different one amongst these. There is also a soft requirement to learn monad transformers (e.g. to understand what liftIO is doing) which made the initial development more difficult. https://subth.ink/ January 20, 2026 at 01:34AM

Show HN: I built a tool for free PDF Resume (CV) hosting – wanna test it? https://ift.tt/Z6cpONs

Show HN: I built a tool for free PDF Resume (CV) hosting – wanna test it? If you are job hunting and you need to host your PDF resume in a professional way, without ads or weird limits, I built Resume.hr . You can upload a resume and write or upload a cover letter. You can add links from other social media profiles, and a QR code is generated automatically. The design is clean and you can even add credentials Linkedin style. You can share your resume in a subdomain like your-name.resume.hr/resume an example I created is https://ift.tt/lzK9asB . We added a tool inside call Activities that you can use to track job-hunting activities, like to whom you sent the resume and follow-ups, and mostly track interaction to help with the job finding. Why I built this? We have another tool where users can share PDF files online but that is made for documents mostly, and the design is for that. Even so, users upload and share their resumes there, so I belive there is a place for such a tool. We are s...

Show HN: I built a system to drive my RC car from anywhere in the world https://ift.tt/GnWS5FN

Show HN: I built a system to drive my RC car from anywhere in the world Wanted to share a project I've been working on. Basically lets you drive an RC car remotely over the internet with live FPV video. I'm arranging outdoor time attack tournaments with friends, somewhere in woods or in the open field. The setup: - Raspberry Pi Zero 2W mounted on the car with a wide-angle camera - ESP32 on the transmitter generating joystick voltages (needed because ARRMA's 2-in-1 ESC/receiver has no accessible inputs) - Cloudflare for the networking magic (TURN, Tunnel, Workers) - Browser-based controls - works on phone or desktop What it does: - ~100-200ms control latency over internet (10-15ms on LAN) - 720p @ 30fps live video - Touch controls on mobile, keyboard on desktop - Admin dashboard for race management - Token-based access so I can let friends drive - Auto-stops if connection drops (safety first) - Adjustable throttle limits - Optional re-streaming to YouTube Built it because I ...

Show HN: Pipenet – A Modern Alternative to Localtunnel https://ift.tt/VvJR6Cs

Show HN: Pipenet – A Modern Alternative to Localtunnel Hey HN! localtunnel's server needs random ports per client. That doesn't work on Fly.io or behind strict firewalls. We rewrote it in TypeScript and added multiplexing over a single port. Open-source and 100% self-hostable. Public instance at *.pipenet.dev if you don't want to self-host. Built at Glama for our MCP Inspector, but it's a generic tunnel with no ties to our infra. https://ift.tt/J9rRuoI https://pipenet.dev/ January 19, 2026 at 11:10PM
