Show HN: unTamper – cryptographically verifiable audit logs for app eventshttps://news.ycombinator.com/item?id=47427580https://untamper.comBuilt this after hitting the same gap on multiple projects: teams log critical events (admin actions, permission changes, PII access) but have no structural way to prove those records weren't altered after the fact.Immutable storage (S3 Object Lock, WORM) are common, but it only covers tampering after the write lands. It doesn't protect against someone with DB write access, and it doesn't give a third party, e.g. an auditor, a way to verify integrity without touching your infrastructure.My approach: hash chaining. Each event is SHA-256 hashed against its canonical payload + the hash of the previous event. Any insertion, deletion, or modification breaks all subsequent hashes. Anyone with the public API can re-verify the chain independently.A few decisions I'm happy to discuss:- Canonicalization before hashing: JSON isn't canonical by default. Ended up writing a strict sorted-key schema rather than fighting recursive serialization. - Per-actor chains vs. one global chMar 18, 2026 4:13 PM

Show HN: Codala, a social network built on scanning barcodeshttps://play.google.com/store/apps/details?id=com.hsynkrkye.codala&hl=enHi HN. I poured months into making a mobile app called Codala, but sadly, it's getting practically zero downloads. I have no marketing budget at all.I'm starting to question if the app is just bad, but the core idea feels solid to me: you scan any QR code or barcode, and it opens up a space to chat, leave reviews, and discuss that specific product or place.I know the app needs users leaving comments to feel alive, but it's been 3 weeks and things are dead quiet. If you want to take a look, I’m totally open to any feedback or honesty.It's only available on Google Play for nowMar 18, 2026 3:17 PM

Show HN: PlanckClaw an AI agent in 6832 bytes of x86-64 assemblyhttps://github.com/frntn/planckclawI built an AI agent that fits in 6,832 bytes. The entire runtime (binary, bridges, tools, config) is ~23 KB.PlanckClaw is written in x86-64 assembly (obviously AI assisted code generation for this one) and uses only 7 Linux syscalls. No libc, no allocator, no runtime. The binary is a pure router: it reads messages from named pipes, asks another pipe what tools exist, builds a JSON prompt, writes it to a third pipe, parses the response, dispatches tool calls, and relays the answer. It never touches the network or executes tools directly.Everything else composes around it in shell scripts (~460 lines total): - bridge_brain.sh: curls the Anthropic API (~90 lines) - bridge_discord.sh: Discord Gateway via WebSocket (~180 lines) - bridge_cli.sh: terminal interface (~40 lines) - bridge_claw.sh: tool discovery and dispatch (~50 lines)Four processes, six named FIFOs, zero shared state. Adding a tool means dropping a shell script in claws/. No restart, no recompilation, no config change.It does Mar 18, 2026 3:07 PM

Show HN: Cloak – .env on disk has fakes, your editor shows them (CLI and VSCode)https://getcloak.devI run AI coding agents with full filesystem access daily — Claude Code, Cursor, the works. Last month I realized every one of them has been reading my .env files with real Stripe live keys, database passwords, and AWS credentials. Sent straight to model providers as "context." .gitignore protects git, not disk. Secret managers protect servers, not laptops. Sandboxing the agent kills its usefulness. Nothing stopped a local cat .env from returning real credentials. So I built Cloak. The .env on disk always contains structurally valid fakes — sk_test_ for Stripe, localhost for databases, AWS example keys. Agents read the file, get sandbox values, write perfectly valid code. The VS Code/Cursor extension intercepts file opens and decrypts from an AES-256-GCM vault so you see real values in your editor. On save, it re-encrypts and writes sandbox to disk. cloak run npm start injects real env vars gated behind Touch ID / password — agents can't authenticate.

Show HN: PingCRM – Open-source personal networking CRMhttps://github.com/sneg55/pingcrmHey HN,Robin Dunbar figured the human brain caps out at roughly 150 stable relationships. After that, people just fall off. Not because you stop caring, but because you can't track that many threads at once. I built PingCRM to push past that limit, not by making you remember more, but by handling the part you're bad at: noticing who's going cold and drafting something worth sending.CRMs exist, but they're built for sales teams. I wanted something for one person maintaining their own network. Specifically:(1) Pull in conversations I'm already having. Gmail threads, Telegram DMs, Twitter DMs, LinkedIn messages, no manual logging.(2) Tell me who's going cold. A relationship score (0–10) based on recency, frequency, reciprocity, and breadth of interaction.(3) Draft the message for me. Claude reads your conversation history, picks the right tone (formal vs. casual), and writes a follow-up that references why now is a good time, like a job change, a long silence, or a fundraising announcemenMar 18, 2026 10:33 AM

Show HN: Helpmarq – Submit any project, get structured feedback from real usershttps://www.helpmarq.com/I built this after noticing a pattern: founders and developers share things they've built, get back vague or overly positive responses, and have no real signal on what to fix. Helpmarq lets you submit any project — landing page, app, side project, pitch deck — and get structured feedback from real users. The review process is guided by specific questions (clarity, value prop, UX, conversion blockers) so reviewers can't just say "looks good." The core insight: feedback quality is a framework problem, not a motivation problem. Most people want to give useful feedback — they just don't know what to look for. Still early. Would love brutal, honest feedback from this community — on the product and on the idea itself. helpmarq.comMar 17, 2026 8:45 PM

Show HN: I built a rental property underwriting app and used it to buy a househttps://brrrrfect.com/Over the last few months, I built Brrrrfect.com as a way to teach myself how to underwrite properties. I've always had a relative disdain for spreadsheets and don't want to give Microsoft money for its office tools, so I decided to build this.I think it would have taken way longer for me to get the hang of underwriting real estate if I hadn't spent time building this and really learning about what the calculations mean.I ended up using this tool to buy my first Buy, Renovate, Rent, Refinance, Repeat (BRRRR) deal and its working out really well! I'm definitely going to keep using it for myself.If it helped me, I figured it might help someone else, so I made it live! Right now it only supports basic residential underwriting and a more advanced BRRRR calculator, but I want to add commercial and farm land underwriting tools in the future as well.I’d love feedback from people who invest in real estate, underwrite deals regularly, or just have opinions on what could make this tool more usefuMar 17, 2026 6:01 PM

Show HN: CredibilityProfile – bringing reference checks earlier into hiringhttps://www.credibilityprofile.com/Hi HN,I’ve been a startup operator and advisor for 10+ years, and one recurring frustration has been hiring, which got even worse with the introduction of some new AI tools: CVs are too polished, too many applications to screen, interview capacity is limited, real signal (how someone actually works) comes late via references — if at all.So we built a small tool: https://credibilityprofile.comIt lets candidates collect structured feedback from past managers/peers (with consent to be contacted), and share it as a reusable link in their CV.We ran an initial pilot in our hiring processes, and seen some promising results: Candidates were willing to complete and then re-use it in their CVs for their other applications.Right now, we’re testing it with other entrepreneurs/hiring managers/recruiters — with a very simple setup, at no cost (just adding a note to job posts).Open questions we’re still thinking about:- Is this meaningfully better than LinkedIn recommendations / references later in pMar 17, 2026 5:06 PM
