Show HN: Open Passkey – open-source passkey auth with free "backendless" host I, like Andrej Karpathy, became super frustrated by how annoying it was to deploy projects that were previously an absolute joy to make with Claude Code. That is why I made open-passkey, an MIT licensed passkey repo with support for 33 languages and frameworks (examples included) that makes adding simple secure auth to a project easy. We are also releasing gateway ( https://ift.tt/Cfi2hpm ) a "backendless" hosted auth server that frontend apps can consume for free so that you can ship a React or Angular app using a CDN like Netlify without needing to configure a server at all. We are willing to freely share the resources of an AWS t.large instance which should easily support millions of accounts & sessions. This decision was made to improve our velocity when it comes to shipping small apps (it should go without saying that this is not designed for large apps). Open-passkey prioritizes post-quantum algorithms, though they are not supported by browsers yet. On top of Gateway, we also built a simple end-to-end encrypted key value store modeled after localStorage. A simple setItem() and getItem() API that uses PRF with passkeys to store encrypted values on gateway with zero config. This, again, was made to improve our velocity to securely add API keys and stuff to frontend apps without needing to pay for a server to host. Obviously gateway is completely optional and exporting out your users public keys is supported with rp_id verification via domain TXT records. https://ift.tt/6SRg9ve April 18, 2026 at 09:12PM

Show HN: I can't write Python. It works anyway Read an article about analyzing Garmin data with AI. Sounded great — except I didn't want to send my health data to any cloud service. So I asked Claude to write me 2-3 scripts and a dashboard. This escalated a bit. 30 days and 20$ later I have this: A local-first Garmin archive with interactive HTML dashboards, Excel exports, weather and pollen context, AES-256 encrypted token storage, and a self-healing data pipeline with 515 automated tests. Windows desktop app, no terminal needed. Nothing leaves your machine. I never wrote a line of Python. I understood the problems and made the architectural decisions. Claude wrote everything else.

Show HN: A site for stopping work slop https://ift.tt/6cx2jXR

Show HN: A site for stopping work slop Artificial intelligence is an amazing tool for brainstorming, programming, or generating images. But it’s also incredibly good at writing long, meaningless text filled with platitudes or producing code that continuously reinvents the wheel or misses edge cases. This has become known as slop. My inboxes have been increasingly filled with low-effort slop. I’m sure that this happens to many of you, too. The reddest of flags is being sent slop for work; at first glance, it may look credible, but it falls apart when you actually read the text. This prompted me to write three principles for working with AI and creating a website to send to your friend or colleague when they send you slop. Let's stop the slop and get back to doing great work together. https://stopnoslop.com/ April 18, 2026 at 02:34AM
