- Hey HN, I’m Jay, a co-founder at Highlight and a YC alum; excited to share our replay-based debugging tool! TLDR; if you're using a tool like Fullstory for debugging, or you have trouble understanding the actual impact of your errors (e.g. in sentry), you should give us a try! We built Highlight because we constantly found ourselves flooded with errors and s
- What engineers like:
- Combines frontend and backend SDKs to provide end-to-end session replay and error tracing. Backend logging integrations link up to the relevant user session for easier debugging. Records network activity & console logs. Supports data masking for privacy. Open source so can be self-hosted, or use the cloud version.
- Trade-offs & limitations:
- Can’t track WebSockets. Frontend session tracking has some client overhead (11kb bundle). The UI has no dark mode.
- Best suited for:
- Developers who need to debug user sessions should consider this tool

# Design Brief: Dark Developer (with Minimal Monochrome)
Deep dark surfaces, monospace typography, terminal/code snippets, and high-precision borders.
## Design Tokens
```css
:root {
--background: #000000;
--surface: #191919;
--foreground: #fbfbfb;
--muted-foreground: #d1d6d9;
--accent: #ddff46;
--radius: 16px;
--font-heading: "headingFont3", ui-sans-serif, system-ui, sans-serif;
--font-body: "bodyFont", ui-sans-serif, system-ui, sans-serif;
--font-mono: "monoFont", ui-monospace, monospace;
}
```
Color area ratio: Background #000000 (~38%) · Surface #191919 (~49%) · Text #FBFBFB (~6%) · Muted Text #D1D6D9 (~4%) · Accent #DDFF46 (~3%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.

## Avoid
