Show HN: Costrace – Open-source LLM cost and latency tracking across providers

Thu, 03/05/2026 - 8:25am

I built Costrace because I was tired of checking three different dashboards to understand my LLM spend.

It's an open-source tool that tracks cost, token usage,latency, geographic distribution across OpenAI, Anthropic, and Google Gemini in one place. The SDKs work by monkey-patching the official client libraries, so you don't change any of your existing code — just init and go. You can self-host the whole thing or use the hosted version at costrace.dev.

GitHub: github.com/ikotun-dev/costrace Happy to answer any questions about the architecture or monkey-patching approach.

Show HN: VideoNinja – paste video URLs, walk away, they download

Thu, 03/05/2026 - 8:24am

Another evening of saving videos before platforms memory-hole them. Terminal not invited. Built a GUI.

Paste URLs. They queue. They download. Disk space on screen. Output folder one click away. Queue survives restarts. Needs yt-dlp and ffmpeg, the app finds them. If it can't, it writes an AI prompt to fix your setup.

Click the ninja. It talks.

Private tool, now public. Mac & Windows installers. MIT.

Show HN: Turn GitHub commits into a publish-ready changelog

Thu, 03/05/2026 - 7:28am

Hi HN,

I kept shipping features without updating my changelog. After enough times a user asked “when did that change?”, I built HeyEmit to fix it.

HeyEmit is a changelog platform that integrates as a GitHub App, listens to repository events, analyzes commit diffs, and generates structured draft changelog entries for you to review and publish.

The goal isn’t to automate releases — it’s to remove the annoying part of writing changelogs so you actually maintain them.

Typical workflow:

- connect your GitHub repo

- define rules for what should trigger changelog entries

- commits generate draft entries automatically

- review, edit, and publish when ready

HeyEmit also provides an embeddable changelog widget for your app or website and a hosted public changelog page so your users can see what's changed.

It's a paid tool, with AI-generated changelog drafts available for projects that want automatic summaries.

I'd love feedback from other developers:

- how do you currently maintain changelogs?

- would something like this fit your workflow?

- what features would make it more useful?

Show HN: BidWix – one-shot price agreement using secret max/min

Thu, 03/05/2026 - 7:24am

Hi HN — I built BidWix, a small negotiation tool for agreeing on a price without haggling.

How it works:

- The buyer enters their true maximum price (kept secret from the seller). - The seller enters their true minimum price (kept secret from the buyer). - If there is overlap, BidWix suggests a single “fair” price using the geometric mean (so the compromise is symmetric in percentage terms, not absolute currency units).

Notes:

- No signup. Email is optional. No ads. - BidWix stops at the price suggestion. It does not handle payment, contracts, escrow, or delivery. - It’s meant for cases where both sides want to make a deal, but don’t want the “you go first” dance. - I’m not a skilled negotiator myself, so I wanted a tool where negotiation skill is less of an advantage. - It seems to work especially well for intangible goods (I’m a sound designer).

If you try it, I’d value feedback on:

- Where the flow feels confusing or too wordy. - Whether the suggested price feels reasonable in real negotiations you’ve had. - Any edge cases or incentive problems you see.

Optional background (rationale + math): https://bidwix.com/articles/why-geometric-mean-feels-fair

A great day to all of you! Stéphane (the guy who built myNoise)
