grep.app vs KeyDrift
Fast public-code search across repositories — repo-side exposure visibility.
Speedy regex search across indexed public repos.
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 grep.app does well
Instant public-code search.,Regex-capable queries.
- Public git repositories.
- Indexed search engines.
- Index refresh cycles.
The gap KeyDrift fills: the deployed bundle
The structural difference is the artifact under inspection. grep.app watches inputs to the build — commits, branches, configuration. KeyDrift watches the output: the HTML and JavaScript a browser downloads from the live URL. Build-time substitution, agent-written client calls and streamed payloads live in that output and in none of the inputs, which is why a green grep.app report and a leaking deployment can coexist without anyone being wrong.
- 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. Free web/API. versus KeyDrift: deployed web artifacts fetched live, or pasted bundle source for anything behind a login.
- Detection approach. developers studying patterns publicly. 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. If your secrets reached PUBLIC repos, these indexes find them instantly — push prevention plus history hygiene address that half; deployment half remains ours. 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 grep.app documents more detail than fits here, follow their docs; where KeyDrift claims something, it is verifiable in a two-minute free scan.
| Capability | grep.app | KeyDrift |
| --- | --- | --- |
| Primary surfaces | Free web/API. | 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__) | Outside source-scan scope | 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 | If your secrets reached PUBLIC repos, these indexes find them instantly — push prevention plus history hygiene address that half; deployment half remains ours. | Scheduled scans diffed into created/regressed/resolved; regression alerts name comebacks |
| Alert routing | If your secrets reached PUBLIC repos, these indexes find them instantly — push prevention plus history hygiene address that half; deployment half remains ours. | 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 grep.app summarize their public documentation as of the verified date above._
Where each one wins
- grep.app 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 grep.app
Nobody rip-and-replaces grep.app, and this page never asks for that. The realistic switch is additive: keep grep.app 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 grep.app 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.
_Compared against grep.app documentation and pricing as verified August 2026. Capabilities change; check their site._ grep.app (OSS/community) and associated marks are trademarks of grep.app (OSS/community), referenced for identification and descriptive comparison.
Bottom line: choose grep.app for its category strengths without hesitation. Choose KeyDrift the moment someone asks what your bundles expose — then keep both, because they were never competing for the same job.
How teams actually run grep.app and KeyDrift together
In practice the pairing is boring in the best way: grep.app 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 grep.app 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.
