[CLI Tool] Show HN: I build a strace clone for macOS Ever since I tested software on macOS, I deeply missed my beloved strace that I use when programs are missbehaving. macOS has dtruss but it's getting locked down and more unusable with every machine. My approach uses the signed lldb binary on the system and re-implements the output you are know from the wonderful strace tool. I just created the tool yesterday evening, so it may have a few bugs, but I already got quiet a few integration tests and I am happy so far with it.

[Monitoring/Observability] Show HN: I ditched Grafana for my home server and built this instead Frustrated by the complexity and resource drain of multi service monitoring stacks, I built Simon. I wanted a single, lightweight dashboard to replace the heavy stack and the constant need for an SSH client for routine tasks. The result is a resource efficient dashboard in a single Rust binary, just a couple of megabytes in size. Its support for various architectures on Linux also makes it ideal for embedded systems and lightweight SBCs.<p>It integrates: Comprehensive Monitoring: Realtime and historical metrics for the host system and Docker containers (CPU, memory, disk usage, and network activity). Integrated File &amp; Log Management: A web UI for file operations and for viewing container logs, right where you need them. Flexible Alerting: A system to set rules on any metric, with templates for sending notifications to Telegram, ntfy, and webhooks. My goal was to create a cohesive, lightweight tool for self hosters and resource constrained environments. I&#x27;d love to get your feedback.<p><a href="https:&#x2F;&#x2F;github.com&#x2F;alibahmanyar&#x2F;simon" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;alibahmanyar&#x2F;simon</a>

[Other] Show HN: 13Radar – Real-Time Hedge Fund Portfolio Analytics Hi HN,<p>We’re a small team working on 13Radar.com, which we launched about two weeks ago after 4 months of development. I’m the founder, and together with the team we’re building a platform that tracks hedge fund portfolios in real-time based on SEC Form 13F filings.<p>AI has been a major helper in our workflow. For a single webpage, we often consult multiple AI systems in parallel, generating different versions and comparing them side by side before deciding on the final design or implementation. More than 60% of the research, design, and coding involved AI assistance. For UI design we used Readdy, which gave us a smooth design experience. We experimented with Google Gemini and ChatGPT for research and prototyping, while most of the coding was done with Claude Code (Trae). On the front-end, we started with Bootstrap but later switched to TailwindCSS for a lighter, more responsive framework.<p>Features so far:<p>Real-time tracking of hedge fund holdings from SEC 13F filings<p>Portfolio changes per quarter (new positions, increases, reductions, exits)<p>Sector-level insights and trend analysis<p>Historical tracking and backtesting tools<p>Next steps:<p>Implementing pricing and subscription features<p>Adding email notifications and report export<p>Expanding analytics with insider transaction data<p>Continuing to refine usability and performance<p>We’d love feedback from the community:<p>Does this solve a real pain point for investors&#x2F;researchers<p>Any thoughts on improving positioning or usability<p>Suggestions for features that would make this more useful<p>Thanks for reading — and if you’re curious, feel free to check out the site and let us know what you think.

[CLI Tool] Show HN: Continuous Claude – run Claude Code in a loop Continuous Claude is a CLI wrapper I made that runs Claude Code in an iterative loop with persistent context, automatically driving a PR-based workflow. Each iteration creates a branch, applies a focused code change, generates a commit, opens a PR via GitHub&#x27;s CLI, waits for required checks and reviews, merges if green, and records state into a shared notes file.<p>This avoids the typical stateless one-shot pattern of current coding agents and enables multi-step changes without losing intermediate reasoning, test failures, or partial progress.<p>The tool is useful for tasks that require many small, serial modifications: increasing test coverage, large refactors, dependency upgrades guided by release notes, or framework migrations.<p>Blog post about this: <a href="https:&#x2F;&#x2F;anandchowdhary.com&#x2F;blog&#x2F;2025&#x2F;running-claude-code-in-a-loop" rel="nofollow">https:&#x2F;&#x2F;anandchowdhary.com&#x2F;blog&#x2F;2025&#x2F;running-claude-code-in-...</a>

[Other] Show HN: I built IncidentPulse after getting paged at 3 AM I built IncidentPulse after the classic &quot;Slack-on-fire, status-page-outdated&quot; outage chaos.

[Other] Show HN: spymux – Spy on your tmux panes I had motivation for writing this after I kept switching back and forth between agents to see if they&#x27;ve finished what they were working on (and I couldn&#x27;t find a similar tool out there). I&#x27;d imagine it can be useful for other scenarios as well, e.g. tracking multiple build&#x2F;test jobs over multiple windows.<p>Still a work in progress, but I thought I&#x27;d share :)

[CLI Tool] Show HN: TalkiTo – enabling voice and Slack for Claude Code and Codex CLI Hey everyone, here is an open source project I&#x27;ve been working on to add voice input&#x2F;output to terminal based coding agents.<p>One thing about the new terminal coding agents I really like is being able to multi-task but right now it&#x27;s a bit like a Tesla on autopilot needing your hands still on the wheel. You need to be checking often if your input is required or if it&#x27;s going off the rails. To be able to go fully hands free I wanted to add TTS and ASR. Then I added slack and WhatsApp hooks to TalkiTo as well.<p>It&#x27;s fully open source with a BYOK philosophy and it&#x27;s configured to work with any of the major ASR&#x2F;TTS providers. It also supports local whisper and kokoro&#x2F;kittentts if you want a decent free&#x2F;private option.<p>It works by wrapping the coding agent and capturing the input&#x2F;output. It does have an MCP server running but thats mainly for configuration - I found that using MCP to speak or listen was too slow. The upshot of the MCP server is you can type (or say) &quot;talkito disable ASR&quot; or &quot;talkito change tts to kokoro&quot;.<p>Here is a demo video I made here: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=pf8jFt0smqs" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=pf8jFt0smqs</a><p>I like to think of it as similar to SuperWhisper but with TTS, the focus on coding agents and configurability.<p>Really curious to get feedback.<p>Thanks!

[Other] Show HN: European tech news in 6 languages I built a multilingual news aggregator for European tech in 6 languages (EN, DE, FR, ES, IT, NL), filterable by audience (consumers, businesses, government) to help users discover relevant European alternatives.<p>A few interesting technical challenges:<p>PATTERN-BASED IMAGE GENERATION Generic AI images all look the same (&quot;holographic businessman with laptop&quot;). I solved this with a JSON database of 60+ concrete visual patterns—context-aware selection prevents repetition. Funding news → coins&#x2F;contracts, security → locks&#x2F;shields. Much more visual diversity. Still needs tweaking though.<p>GRADUAL SITEMAP GROWTH FOR NEW SITES Daily news pipeline generates lots of content. Challenge: Google indexes new sites slowly—exposing all 2K+ URLs at once resulted in 1-3% indexing rate. Solution: Dynamic rolling window in sitemap—only expose top 50 most recent articles (300 URLs), gradually increasing to 100 → 150 → 200 over 6 months as site builds authority. Result: Indexing rate improved to 10%.<p>AUTOMATED TRANSLATION PIPELINE RSS aggregation → AI summaries and translation with context-aware prompts → human review queue. Still tweaking quality per language pair.<p>STACK: Next.js 15 with Turbopack, PostgreSQL, deployed via Sliplane@Hetzner which works pretty ok.<p>STATUS: 1+ month post launch, 80 pages indexed, 100+ European apps featured (Mollie, Wire, Ecosia, LanguageTool, etc.)<p>FEEDBACK WELCOME ON: • European news sources I&#x27;m missing? • Better approaches to multilingual SEO? • Translation quality red flags? • How to optimize for LLM discovery (ChatGPT, Claude, etc.)?
