Burp Suite vs KeyDrift
The practitioner standard for manual web testing — with TruffleHog extension existing for proxy traffic.
Dominant interactive testing platform with extension ecosystem.
This page compares the two honestly: strengths credited specifically, differences traced to structure rather than quality, and a decision rule at the end. Verified August 2026.
What Burp Suite does well
Unmatched manual-testing tooling.,Extension ecosystem (incl. secret scanning via TruffleHog).,Training/certification culture.
- Proxied/targeted traffic during sessions.
- Analyst-driven tooling.
- Session-scoped only.
The gap KeyDrift fills: the deployed bundle
Where the two diverge is timing and target. Burp Suite evaluates work as it moves through your pipeline; KeyDrift evaluates what has already shipped, from the outside, the way an attacker or a researcher would fetch it. The gap between those two views is not theoretical — it is exactly where NEXT_PUBLIC_ substitutions and copied-in demo keys live.
- Fetched-and-diffed scanning of live URLs, including chunks reachable only through route manifests.
- Streamed server data (
self.__next_f.push,window.__NUXT__) read as carefully as chunk files. - Calibrated dispositions: Supabase anon keys, publishable keys and Firebase web keys recognised as public-by-design instead of reported as leaks.
- Drift transitions — created, regressed, resolved — so a reintroduced key alerts as a regression, not as news.
Feature-by-feature
- Surfaces scanned. Licensed install. versus KeyDrift: deployed web artifacts fetched live, or pasted bundle source for anything behind a login.
- Detection approach. expert-led assessments. versus KeyDrift: 21 secret detectors across 13 providers with placeholder rejection, alphabet-normalised entropy, payload decoding and a confidence floor below which matches are dropped rather than caveated.
- Change over time. Expert sessions sample deeply but episodically; scheduled credential inventories need no expert present — both models valid. versus KeyDrift: scheduled scans diffed into created/regressed/resolved with alert routing to email, Slack, Discord and webhooks.
- Getting started. undefined versus KeyDrift: paste a URL at /scan — free, no account — or paste source for private surfaces.
Side-by-side
Every cell below states a specific capability. Where Burp Suite documents more detail than fits here, follow their docs; where KeyDrift claims something, it is verifiable in a two-minute free scan.
| Capability | Burp Suite | KeyDrift |
| --- | --- | --- |
| Primary surfaces | Licensed install. | Deployed web artifacts fetched live: HTML, all chunks (incl. route-manifest-only), streamed payloads |
| Build-time substitution (NEXT_PUBLIC_/VITE_) | Not a documented capability | Detected in served output — exactly where it lands |
| Hydration payloads (self.__next_f.push, window.__NUXT__) | Vulnerability-focused tooling; credential payload reading not documented | Read as carefully as chunk files |
| Public-vs-secret calibration | Not applicable to scope | Dispositions built-in: anon/publishable/Firebase-web reported informational, sample keys rejected by name |
| Change over time | Expert sessions sample deeply but episodically; scheduled credential inventories need no expert present — both models valid. | Scheduled scans diffed into created/regressed/resolved; regression alerts name comebacks |
| Alert routing | Expert sessions sample deeply but episodically; scheduled credential inventories need no expert present — both models valid. | Email · Slack · Discord · raw webhooks with per-destination severity thresholds |
| Getting started | undefined | Paste any URL at keydrift.dev/scan — free, no account; paste-source mode for behind-login surfaces |
| Privacy of findings | Varies by vendor | Masks + salted fingerprints only; no column anywhere can hold a live secret |_Cells describing Burp Suite summarize their public documentation as of the verified date above._
Where each one wins
- Burp Suite wins when undefined
- KeyDrift wins when the question is “what credentials can strangers retrieve from this deployment right now?” — live fetching, calibrated dispositions, and regression alerting without agents installed.
Switching from Burp Suite
Nobody rip-and-replaces Burp Suite, and this page never asks for that. The realistic switch is additive: keep Burp Suite as the system of record for its domain, give KeyDrift the URLs you serve to strangers, and let drift alerting catch the reintroductions that neither tooling nor memory catches today.
undefined
Decision rule
- Keeping Burp Suite for its documented strengths makes sense — it earns them.
- Add KeyDrift when deployment truth matters: post-build artifacts, preview URLs, and reintroduction watch on a schedule.

Bottom line: if your question is “is our source clean?”, Burp Suite may already answer it well. If your question is “what can a stranger pull from our live JavaScript right now?” — only a scanner that fetches deployments can answer, and that is the entire product on this side of the table.
How teams actually run Burp Suite and KeyDrift together
In practice the pairing is boring in the best way: Burp Suite stays authoritative for whatever it was built to do, KeyDrift runs on a schedule against every public deployment, and alerts route into the same channels your team already reads. Nothing is migrated; nothing is turned off. The only new habit is reading one more alert type — and that one arrives masked, classified, and linked to a fix guide.

Common questions
Is Burp Suite bad at security?
No — the page credits specific strengths above. The difference is which artifact gets inspected, not effort or care.
Pricing comparison?
Their list pricing lives on their site and changes; ours sits on the plans page with findings visible free at every tier. Numbers go stale; philosophy does not.
