Alternatives to bundler-audit
bundler-audit is a free RubySec gem that checks Gemfile.lock against ruby-advisory-db (offline once the database is fetched) and flags insecure http:// or git:// sources. It reports CVSS severity where an advisory carries one, but no EPSS or CISA KEV data. GeekWala covers RubyGems plus 7 other ecosystems via OSV, adding EPSS, CISA KEV and a dashboard.

Feature Comparison
| Feature | bundler-audit | GeekWala |
|---|---|---|
| Vulnerability data | ruby-advisory-db (community-maintained) | OSV (ingests GHSA data) + EPSS + CISA KEV |
| Prioritization Key difference | CVSS severity where available | EPSS exploit probability + CISA KEV |

| Offline operation | Yes, after advisory-db fetch | |
| Interface | CLI output only | Web dashboard + REST API |
| Ecosystems | Ruby (RubyGems) only | 8 ecosystems: npm, PyPI, Maven, Go, Rust, RubyGems, NuGet, Packagist |
| CI integration | Any CI via gem install bundler-audit | Yes (Pro) — plus scheduled scans |
| Scheduled / recurring scans | Not built in — schedule via CI | Yes (Pro) |
| Maintainer | RubySec project (community) | Independent |
| Privacy | Local CLI, fully offline capable | Package names only, no source code |
| Price | Free and open source | Free tier + $12/mo or $99/yr Pro (flat-rate, unlimited projects) |
When to Use Each
When to use bundler-audit
bundler-audit is the right choice when:
- You work primarily in Ruby and want the ecosystem-standard, offline-capable CLI check
- You need insecure gem-source-URI detection alongside vulnerability scanning
- You want a zero-cost, self-hosted tool with no external account
When to use GeekWala
GeekWala is the better fit when:
- You need to prioritize by real-world exploit probability, not CVSS severity alone
- You want CISA KEV (confirmed active exploitation) flagged as its own field
- You manage projects across multiple ecosystems, not just Ruby
- You want a web dashboard to share results with your team, alongside bundler-audit in CI
Detection vs Prioritization
EPSS Exploit Probability
bundler-audit's own output shows CVSS severity where the advisory carries one, with no exploit-probability signal. GeekWala layers EPSS on OSV advisory data, so exploitation probability — not just theoretical severity — drives what you fix first.
CISA KEV Alongside EPSS
bundler-audit does not indicate CISA KEV status — a confirmed actively-exploited CVE looks identical to a theoretical one in its report. GeekWala flags KEV entries as a separate field on every finding, ranked first.
Built to Run Alongside bundler-audit, Not Replace It
bundler-audit in your Ruby CI for offline-capable, ecosystem-native checks (including insecure-source detection GeekWala does not do); GeekWala for cross-ecosystem, EPSS/KEV-enriched triage and a web dashboard.

Frequently Asked Questions
Is GeekWala a bundler-audit replacement?
Not necessarily — bundler-audit is free, official to the Ruby ecosystem, and also detects insecure gem source URIs, which GeekWala does not do. GeekWala adds EPSS exploit-probability and CISA KEV enrichment for triage, plus a hosted dashboard and 7 ecosystems beyond Ruby. Many teams run both.
What is ruby-advisory-db?
A community-maintained, git-based database of CVE/GHSA advisories for RubyGems, published by the RubySec project and consumed by bundler-audit. OSV.dev (the source GeekWala uses) also ingests GitHub Advisory Database data, so coverage overlaps substantially.
How does GeekWala prioritization differ from bundler-audit?
bundler-audit's report lists advisories with CVSS severity where the advisory carries one — it has no exploit-probability signal. GeekWala ranks the same OSV-sourced findings by CISA KEV (confirmed active exploitation) first, then EPSS score above 10% (30-day exploit probability), then severity, with EPSS breaking ties.
Can I use both bundler-audit and GeekWala?
Yes. Run bundler-audit in CI for fast, offline-capable checks (including insecure-source detection) on every Ruby build, and use GeekWala for cross-ecosystem visibility and EPSS/KEV-based triage of what to fix first.
Is GeekWala free like bundler-audit?
GeekWala has a free tier with 5 projects and 50 scans per month. bundler-audit is fully free and open source with no usage limits — for Ruby-only projects that never need multi-ecosystem coverage, bundler-audit alone may be enough.
