GeekWala vs OSV-Scanner — Raw OSV Coverage vs Exploitation Prioritization

OSV-Scanner is Google's free, open-source CLI that queries the OSV database and reports vulnerabilities with a CVSS score. GeekWala scans the same OSV data but adds EPSS exploitation probability and CISA KEV flags to every finding, plus a hosted dashboard, scan history, and scheduled scans OSV-Scanner doesn't have. If you want a free, local, scriptable scanner, OSV-Scanner is excellent. If you want to know which of those vulnerabilities attackers are actually exploiting — without reading the OSV JSON yourself — that's the layer GeekWala adds.

Here's the honest starting point: GeekWala and OSV-Scanner both draw their vulnerability data from OSV.dev. When it comes to which CVEs each tool finds for a given lockfile, they largely agree — same open advisory feed underneath. So this isn't a "who finds more bugs" comparison. It's a comparison of what each tool does with the findings, and how you're expected to run it.

OSV-Scanner is a command-line tool. You install a Go binary, point it at a lockfile or directory, and it prints a table. GeekWala is a hosted service: you paste a lockfile (or connect a repo) and get an enriched, sortable, persistent view back. Those two shapes suit different teams, and neither is strictly better.

The comparison axes

1. Vulnerability data source

Comparable — and that's the whole point. OSV-Scanner is, in Google's own words, "an officially supported frontend to the OSV database." GeekWala scans OSV too, alongside NVD and GHSA. For the ecosystems both tools cover, they're reading from largely the same advisory pool, so they surface largely the same CVEs. If a tool claimed to find dramatically more vulnerabilities than OSV-Scanner on the same lockfile, you'd be right to be skeptical. GeekWala doesn't make that claim. The difference is what happens after the CVE list exists — not the list itself.

2. EPSS exploitation probability

GeekWala wins. OSV-Scanner's default output shows an OSV URL, a CVSS score, the ecosystem, the package, the current and fixed versions, and the source file. That's it for severity — CVSS, and nothing about exploitation likelihood. EPSS scores don't appear anywhere in its documented output.

GeekWala shows an EPSS score on every finding. That matters because CVSS and EPSS answer different questions. CVSS asks "how bad could this be if exploited?" EPSS asks "how likely is it to actually be exploited in the next 30 days?" Rank a backlog by CVSS alone and a theoretical 9.8 in a code path you never call sits at the top next to a 6.5 that's being weaponized right now. EPSS pulls the second one up where it belongs.

CVSS × EPSS Priority Matrix: A 2-by-2 grid showing four vulnerability triage zones based on CVSS severity (horizontal axis) and EPSS exploitation probability (vertical axis). Approximately 81% of CVEs fall in the Low Priority quadrant, 11% in Plan & Monitor, 4% in Investigate Fast, and 4% in Patch Now (critical priority).
▲  EPSS Score — Exploit Probability (high → low)
CVSS Score — Severity
⚡Investigate Fast
~4%
Low CVSS score, but threat actors are actively exploiting it. npm audit misses this. Patch this week.
EPSS High · CVSS Low
🚨Patch Now
~4%
High severity AND being exploited. Drop everything — patch within 24–48 hours. Likely on CISA KEV.
Critical Priority
✓Low Priority
~81%
Low severity, rarely exploited. Batch with quarterly maintenance. Don't let noise drown real threats.
Scheduled Maintenance
⚠Plan & Monitor
~11%
High severity but nobody is exploiting it yet. Schedule for next sprint — don't panic.
EPSS Low · CVSS High
◀ CVSS < 7.0 · Low / Medium
CVSS ≥ 7.0 · High / Critical ▶
~85% of CVEs are noise (bottom-left). Focus energy on the top row — especially top-right where severity meets active exploitation.

With OSV-Scanner you can absolutely get EPSS — by exporting JSON and joining it against FIRST's EPSS feed yourself. GeekWala just does that join for you and puts the number in the column.

3. CISA KEV flagging

GeekWala wins. The CISA Known Exploited Vulnerabilities catalog is the least ambiguous "this is being exploited in the wild" signal available. GeekWala flags KEV status on every matching finding. OSV-Scanner does not surface CISA KEV in its output.

KEV entries are rare in application dependencies, but when one shows up it should jump the queue regardless of CVSS. A KEV-listed CVSS 5.0 outranks a non-KEV CVSS 9.8 on your patch list every time — and a tool that doesn't show KEV status can't make that ordering for you.

4. Local and offline scanning

OSV-Scanner wins. This is a genuine architectural advantage, not a footnote. OSV-Scanner runs entirely on your machine and supports an --offline mode against a downloaded local database — "no network connection is required after the initial database download." For air-gapped environments, regulated shops that can't send dependency manifests to a third party, or anyone who simply doesn't want their lockfile leaving the building, that's decisive.

GeekWala is a hosted service. Your lockfile goes to GeekWala's servers to be scanned. For many teams that's a non-issue; for some it's a hard blocker. If it's a blocker for you, OSV-Scanner is the correct choice and no amount of EPSS enrichment changes that.

5. Container scanning and reachability

OSV-Scanner wins. V2 added layer-aware container image scanning for Debian, Ubuntu, and Alpine — it identifies which image layer introduced each package and filters vulnerabilities unlikely to affect the running container. It also has an experimental call-analysis mode (--call-analysis) that checks whether vulnerable code paths are actually invoked, which cuts down false positives at the source. And it ships guided remediation for npm and Maven, recommending version upgrades by dependency depth, severity, and fix strategy.

GeekWala scans dependency manifests and lockfiles across eight ecosystems; it doesn't scan container images, do reachability analysis, or open remediation PRs. If your threat model is "what's in this Docker image and is the vulnerable function even reachable," OSV-Scanner does work GeekWala doesn't attempt.

6. History, scheduling, and the dashboard

GeekWala wins. OSV-Scanner is stateless by design — each run prints a report (table, JSON, SARIF, SPDX, CycloneDX, or an interactive HTML file) and forgets. There's no persistent history of how a project's exposure changed over time, no scheduled re-scans, and no cross-project view; you wire that up yourself with cron and your own storage.

GeekWala keeps scan history, runs scheduled scans on Pro, and shows findings across all eight ecosystems in one dashboard. For teams running Python next to Node next to Go, seeing every project's exploitable findings in a single sortable view — rather than eight separate CLI runs — is the day-to-day difference.

7. Cost and licensing

OSV-Scanner wins on price; it's free and always will be. It's Apache-2.0 licensed open source from Google, with no seats, no tiers, and no usage caps. You can read the code, fork it, and embed it as a Go library. Nothing GeekWala offers competes with free.

GeekWala has a free tier for anonymous and light use and a flat-rate Pro plan (see pricing) — flat-rate, not per-seat, so it doesn't punish you for adding teammates. You're paying for the enrichment and the hosted workflow, not for access to vulnerability data you could get for free. Whether that's worth it depends entirely on how much your team's time is worth versus building the EPSS/KEV/history layer yourself on top of OSV-Scanner.

Where OSV-Scanner is genuinely better

Free and open source (Apache-2.0) — no cost, no lock-in, embeddable as a library
Local and offline scanning (--offline) — nothing leaves your machine; air-gap friendly
Container image scanning — layer-aware, with base-image analysis
Reachability / call analysis — checks whether vulnerable code is actually invoked
Guided remediation — suggests concrete version upgrades for npm and Maven
Native SBOM output — SPDX and CycloneDX straight from the CLI
CI-native and scriptable — a single binary that drops into any pipeline

If your priorities are cost, data privacy, container coverage, or embedding a scanner into your own tooling, OSV-Scanner is the stronger — and often the correct — choice.

Where GeekWala is better

EPSS scores on every finding, no JSON wrangling required
CISA KEV flagging on every finding
Prioritized triage — sort by exploitation probability instead of CVSS
Persistent scan history and scheduled scans (Pro)
Cross-ecosystem dashboard — 8 ecosystems in one sortable view
Anonymous web scanning — paste a lockfile, no install, no account

If your priority is "which of these 60 CVEs should we actually patch this week," GeekWala answers that in the interface. OSV-Scanner gives you the raw list and leaves the prioritization to you.

The honest verdict

These tools aren't really rivals — they're two layers of the same stack. OSV-Scanner is the free, local, open-source engine that turns a lockfile into a vulnerability list. GeekWala is the enrichment-and-triage layer that turns that list into a patch order.

Plenty of teams run both: OSV-Scanner in CI to gate builds and scan containers offline, GeekWala for weekly triage to separate "exploited today" from "theoretical forever." That combination costs nothing but a Pro plan and gives you both air-gapped coverage and exploitation-aware prioritization.

If you're picking just one: OSV-Scanner if cost, privacy, container scanning, or scriptability lead your list. GeekWala if you'd rather not build the EPSS + KEV + history layer yourself and want prioritization handed to you in a dashboard.
