[Other] Show HN: langdiff – Stream valid JSON from LLMs with type-safe callbacks Ever had json.loads() explode halfway through an LLM stream? langdiff fixes that with a schema + callback approach.<p>Define your schema → attach callbacks → push streaming tokens → get structured events immediately.

[Other] Show HN: Turn your iPhone into a local OCR server using Vision Framework Built an iOS app that runs a local OCR server using Apple&#x27;s Vision Framework.<p>Creates a REST API endpoint accessible from any device on your network. No cloud services needed - everything processes locally on the phone.<p>Available on App Store (searching &quot;OCR Server&quot;).<p>Would appreciate feedback on the architecture or similar mobile-as-server projects you&#x27;ve seen.

[Other] Show HN: Created 60 free useful tools in one place Hey there, I&#x27;m a solo dev behind KewlTools.<p>So I&#x27;m one of those people who like to build their own tools&#x2F;utilities whenever they a) want to get something done, or b) want to learn something. c) don&#x27;t want to spend ages finding a utilty and going through walls of ads.<p>I gradually built 66 tools, all free, fast, ad-free, and zero login.<p>I (and my family&#x2F;friends) use these daily, so thought some of you will find it useful!<p>Any suggestions, improving current tools or adding new ones, please let me know.

[Other] Show HN: Omnara – Run Claude Code from anywhere Hey ya’ll, Ishaan and Kartik here. We&#x27;re building Omnara (<a href="https:&#x2F;&#x2F;omnara.com&#x2F;">https:&#x2F;&#x2F;omnara.com&#x2F;</a>), an “agent command center” that lets you launch and control Claude Code from anywhere: terminal, web, or mobile — and easily switch between them.<p>Run &#x27;pip install omnara &amp;&amp; omnara&#x27;, and you&#x27;ll have a regular Claude Code session. But you can continue that same session from our web dashboard (<a href="https:&#x2F;&#x2F;omnara.com&#x2F;">https:&#x2F;&#x2F;omnara.com&#x2F;</a>) or mobile app (<a href="https:&#x2F;&#x2F;apps.apple.com&#x2F;us&#x2F;app&#x2F;omnara-ai-command-center&#x2F;id6748426727">https:&#x2F;&#x2F;apps.apple.com&#x2F;us&#x2F;app&#x2F;omnara-ai-command-center&#x2F;id674...</a>).<p>Check out a demo here: <a href="https:&#x2F;&#x2F;www.loom.com&#x2F;share&#x2F;03d30efcf8e44035af03cbfebf840c73" rel="nofollow">https:&#x2F;&#x2F;www.loom.com&#x2F;share&#x2F;03d30efcf8e44035af03cbfebf840c73</a>.<p>Before Omnara, we felt stuck watching Claude Code think and write code, waiting 5-10 minutes just to provide input when needed. Now with Omnara, I can start a Claude Code session and if I need to leave my laptop, I can respond from my phone anywhere. Some places I&#x27;ve coded from include my bed, on a walk, in an Uber, while doing laundry, and even on the toilet.<p>There are many new Claude Code wrappers (e.g., Crystal, Conductor), but none keep the native Claude Code terminal experience while allowing interaction outside the terminal, especially on mobile. On the other hand, tools like Vibetunnel or Termius replicate the terminal experience but lack push notifications, clean UIs for answering questions or viewing git diffs, and easy setup.<p>We wanted our integration to fully mirror the native Claude Code experience, including terminal output, permissions, notifications, and mode switching. The Claude Code SDK and hooks don&#x27;t support all of this, so we made a CLI wrapper that parses the session file at ~&#x2F;.claude&#x2F;projects and the terminal output to capture user and agent messages. We send these messages to our platform, where they&#x27;re displayed in the web and mobile apps in real time via SSE. Our CLI wrapper monitors for input from both the Omnara platform and the Claude Code CLI, continuing execution when the user responds from either location. Our entire backend is open source: <a href="https:&#x2F;&#x2F;github.com&#x2F;omnara-ai&#x2F;omnara" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;omnara-ai&#x2F;omnara</a>.<p>Omnara isn&#x27;t just for Claude Code. It&#x27;s a general framework for any AI agent to send messages and push notifications to humans when they need input. For example, I&#x27;ve been using it as a human-in-the-loop node in n8n workflows for replying to emails. But every Claude Code user we show it to gets excited about that application specifically so that’s why we’re launching that first :)<p>Omnara is free for up to 10 agent sessions per month, then $9&#x2F;month for unlimited sessions. Looking forward to your feedback and hearing your thoughts and comments!

[Other] Show HN: Enter your domain and my open-source agent will hack it I built an open-source AI agent for security testing to find and fix vulnerabilities in your code.<p>I’ve noticed how bad security vulnerabilities have gotten with everyone shipping AI code slop, so I wanted to build something that allows for vibe-coding at full speed without compromising security.<p>Traditional security tools aren’t effective, and manual pen-testing can’t keep up with the rapidly growing AI code<p>This tool runs your code dynamically, finds vulnerabilities, and validates them through actual exploitation.<p>You can either run it against your codebase or enter your (or someone else’s) domain to scan for vulnerabilities.<p>Good luck, have fun, hack responsibly!

[Other] Show HN: Real-time privacy protection for smart glasses I built a live video privacy filter that helps smart glasses app developers handle privacy automatically.<p>How it works: You can replace a raw camera feed with the filtered stream in your app. The filter processes a live video stream, applies privacy protections, and outputs a privacy-compliant stream in real time. You can use this processed stream for AI apps, social apps, or anything else.<p>Features: Currently, the filter blurs all faces except those who have given consent. Consent can be granted verbally by saying something like &quot;I consent to be captured&quot; to the camera. I&#x27;ll be adding more features, such as detecting and redacting other private information, speech anonymization, and automatic video shut-off in certain locations or situations.<p>Why I built it: While developing an always-on AI assistant&#x2F;memory for glasses, I realized privacy concerns would be a critical problem, for both bystanders and the wearer. Addressing this involves complex issues like GDPR, CCPA, data deletion requests, and consent management, so I built this privacy layer first for myself and other developers.<p>Reference app: There&#x27;s a sample app (.&#x2F;examples&#x2F;rewind&#x2F;) that uses the filter. The demo video is in the README, please check it out! The app shows the current camera stream and past recordings, both privacy-protected, and will include AI features using the recordings.<p>Tech: Runs offline on a laptop. Built with FFmpeg (stream decode&#x2F;encode), OpenCV (face recognition&#x2F;blurring), Faster Whisper (voice transcription), and Phi-3.1 Mini (LLM for transcription analysis).<p>I&#x27;d love feedback and ideas for tackling the privacy challenges in wearable camera apps!

[Other] Show HN: ServerBuddy – GUI SSH client for managing Linux servers from macOS Hi HN,<p>I&#x27;ve built an app for macOS that allows performing common SSH operations on Linux servers using a native GUI.<p>The problem:<p>Managing multiple Linux servers usually means juggling terminal windows and copy-pasting snippets&#x2F;scripts. After dealing with tens of production&#x2F;staging VPSes at previous jobs, I realized there had to be a better way for common operations I did on a daily basis than my collection of bash snippets.<p>Features:<p>- Quickly switch between different servers. Tag servers with arbitrary key values for easy search.<p>- Real-time dashboard with CPU&#x2F;memory graphs, disk usage, and uptime.<p>- Table based interface for processes (sortable&#x2F;filterable), Docker containers, systemd services, network ports, and system logs etc.<p>- Built-in file browser.<p>- Full-featured terminal when you need to drop to the command line.<p>You can check out the screenshots at <a href="https:&#x2F;&#x2F;serverbuddy.app&#x2F;screenshots" rel="nofollow">https:&#x2F;&#x2F;serverbuddy.app&#x2F;screenshots</a> for a quick overview of the features supported.<p>All the above are done through SSH, there are no agents&#x2F;scripts to install on your servers.<p>From using the app for a few weeks(admittedly a short duration), I can say I much prefer the ServerBuddy based workflow to my previous workflows.<p>Pricing:<p>Free forever for one server, $59 one-time for unlimited servers (includes 1 year of updates).<p>If you&#x27;re a developer or sysadmin managing Linux servers from Mac, please do try out the app. I&#x27;d love your feedback regarding additional features&#x2F;workflows etc.<p>Thank you!
