Client‑side HAR inspection and troubleshooting for support engineers, SREs, and developers. Surface likely causes for failures and slowdowns without wading through raw HAR files.
Status: In active development Privacy: Local‑only, runs entirely in the browser
- Request‑centric analysis with contextual findings
- Progressive disclosure UI for fast scanning and deep dives
- Privacy‑first: no uploads, no persistence
Current UI: request table + details panel with findings context.
Build an opinionated diagnostic assistant that reduces HAR cognitive overload:
- Surface the most important signals first.
- Attach findings to specific requests whenever possible.
- Provide clear, actionable explanations instead of raw data.
- Keep the interface clean and use progressive disclosure for deep dives.
- Client‑side analysis: HAR files are parsed locally in the browser.
- Request‑centric UI: results table + request details panel + findings view.
- Findings engine: rules for failures, auth, CORS, performance, payload size, and timing anomalies.
- Severity and confidence: findings carry severity + confidence and are deduped.
- Timing attribution: slow requests call out dominant phases when clear.
- Privacy‑first workflow: no uploads, no persistence.
- Findings UX polish: clearer grouping, richer evidence snippets, and more scannable layout.
- Token analysis: deeper correlation and smarter authentication context.
- Findings summaries: top causes and “why” explanations with supporting evidence.
- Rule expansion: fewer false positives, more context‑aware messaging.
- Guided capture UX: improved HAR capture guidance and onboarding.
- Open https://inspect.replin.ai in your browser.
- Upload a HAR file (processed locally).
- Review request‑level findings and timing breakdowns.
- Drill into request details for evidence and context.
- Token analysis is disabled (coming soon).
- Large JavaScript response bodies are not rendered for performance.
- Findings UX is still in refinement (grouping and evidence snippets evolving).
- Not a DevTools replacement.
- Not a packet sniffer.
- Not an AI black box.
- Not a raw HAR dumper.
HAR data is processed locally in the browser and is never uploaded or stored by the app.
