Scrape Automate Build

Give Traceminer a HAR file (a recording of any website's network traffic) and we will reverse engineer its entire API's in minutes.

Chat with the HAR to understand the site, spot issues, scrape data, run API flows, and export results in any format you need. No official API's needed.

Currently in alpha release. Only invited users can access the platform.

`POST /auth/login` sets the session cookie.
`POST /auth/refresh` rotates the bearer token.

Use Cases

Your HAR file knows everything. Ask it anything.

Most tools hit a wall when your HAR grows large. TraceMiner is purpose-built for it — thousands of requests, megabytes of trace data, processed without truncation.

api Reverse Engineer Zero source code needed

X-ray any website's backend

Curious how your favourite app actually works? Upload its HAR and ask TraceMiner anything — which APIs get called, what each returns, how auth flows, how data is paginated. The entire backend, laid bare.

data_object Data Scraping Sandbox replay

Scrape data — zero code written

TraceMiner infers API patterns from HAR responses and replays them in a sandboxed environment. Just say what you need — download the results or export a ready-to-run cURL or Python script.

Why generic LLMs fail

memory

Big HAR files break them

Generic LLMs hit context limits fast when the trace gets large

block

Important requests get lost

Long chains are dropped, compressed, or only partially read

psychology_alt

They start making things up

Once context runs thin, answers can sound sure but be wrong

If the trace did not capture something, it says so clearly instead of hallucinating

troubleshoot Debug & Document

Debug issues & generate docs instantly

Drop the HAR, ask what broke, and TraceMiner surfaces the failing request, explains the root cause, and turns the flow into polished docs your team can use immediately.

bug_report Debug description Docs account_tree Flow bolt Fixes

Upload the working HAR. Upload the broken one. Find what broke fast.

A simpler flow: compare both traces, let TraceMiner isolate the split, and get a clear explanation of the request or state change that caused the failure.

Working vs failing

Trace comparison

Compare the working flow with the failing one.

Drop in both HAR files and TraceMiner lines up the real request chain so you can stop guessing where the break happened.

search_insights

Root cause signal

Mismatch surfaced

Surface the exact mismatch that caused the bug.

Headers, cookies, redirects, anti-bot checks, payload changes, missing steps. The trace tells the story once the noise is removed.

bolt

Actionable output

Short path to fix

Keep the output simple: what changed, where it changed, and why it failed.

Instead of scrubbing thousands of requests by hand, you get a short path to the root cause and a concrete explanation you can act on immediately.

Working HAR

200 on callback

Cookie and redirect chain stay intact.

Non-working HAR

302 loop on callback

`state` cookie drops before the OAuth callback returns.

TraceMiner diff

mismatch isolated
Flow diverges after `GET /oauth/callback`.
Working trace sends `cookie: state=...` before redirect follow-up.
Broken trace loses the cookie, so auth restarts and loops.
schedule Coming Soon Available by May 10

Every website has a private API. Now you own it.

TraceMiner turns a captured browser session into a battle-tested SDK — complete with auth, cookies, and automatic self-repair — in the time it takes to write a Slack message.

AI Discovery

Surface hidden APIs in seconds

Private endpoints that take months of manual reverse engineering are exposed in a few clicks. AI agents sweep your entire HAR — no matter the size — and filter exactly what you asked for. Payment flows, product catalogues, auth tokens — just tell the AI and it zeroes in.

02

SDK Generation

Precision SDK, shaped to your spec

Don't need the whole API surface? Just say so. Describe the data or output format you want and TraceMiner selects only the relevant endpoints, strips the clutter, and generates a typed SDK in Python, TypeScript, Go, or Rust — not a generic dump, your exact requirements.

03
robot_2
Auto-Fix Loop

Sandbox runs until it works

TraceMiner executes the generated SDK live in an isolated sandbox. Wrong headers? Expired cookie? Unexpected schema? The AI diagnoses the failure, patches the code, and reruns automatically — looping until every call returns 200. Auth and session state handled end-to-end.

Unlimited Potential

SDK in hand. Sky's the limit.

A working SDK is your launchpad. Build scrapers, automate workflows, pipe data into dashboards, create integrations your competitors can't copy — without reversing a single byte by hand. If a website has an API and you can capture it, TraceMiner hands you the keys.

electric_bolt

What used to take an entire engineering sprint now takes minutes.

No API docs. No insider access. No months of manual tracing. The SDK generation flow is coming soon, with availability targeted by May 10.

Personal data visibility

Answer the questions closed products never answer cleanly, like how much you spent, what changed in your account, or which requests power the dashboard you already use.

Capture a workflow once, expose the real request chain, and turn repetitive admin work into something your agent can actually execute.

Ready to Start

Stop asking for access.
Upload the HAR and start building.

The web was already speaking through its network layer. Capture the trace, let TraceMiner read it, and ship the thing that used to die behind closed APIs.

Do I need to format the HAR in a special way? +

No. Export the HAR from your browser session and upload it as-is. TraceMiner reads the captured traffic and lets you ask for the flow, bug, or endpoint you care about.

What if the HAR is large or noisy? +

That is exactly the problem TraceMiner is built for. It pulls signal out of thousands of requests and tells you clearly when something was never captured.

Can this help before SDK generation is live? +

Yes. You can already use TraceMiner to understand hidden flows, debug failures, and extract the real request chain behind a product or workflow.
