The alternatives in detail
In order of how closely each one matches Mobb.

Seal Security
4.1Not listed
vs Mobb+0.1
Remediation agent that ships production-ready fixes for open source vulnerabilities.
- Production-ready fixes for open source vulnerabilities
- Backported patches that avoid breaking version upgrades
- Human vetting of fixes before delivery
Backports avoid forcing breaking dependency upgrades
Ecosystem coverage should be confirmed for less common languages

Superagent
4.0Free
vs MobbSame
An AI security service that finds vulnerabilities in repos, web apps and agents, then fixes them.
- Finds and fixes vulnerabilities rather than only reporting them
- Covers repositories, web applications and AI agents
- Continuous scanning rather than periodic penetration testing
Delivering fixes removes the step where security work usually stalls
Automated fixes still require review before merging

ZeroThreat.ai
4.0$100/mo
vs Mobb$80 moreSame
AI-powered DAST scanner checking web apps and APIs against 40,000+ vulnerabilities.
- DAST scanning across web applications and REST APIs
- Library of 40,000+ vulnerability checks
- Vendor-stated 98.9% detection accuracy with low false positives
Free tier lets you scan before committing to a plan
Per-target pricing grows costly across a large application estate

Vicarius
4.1Not listed
vs Mobb+0.1
VRx delivers automated patching, patchless protection and script-based remediation.
- Automated patching across apps, OS and third-party software
- Patchless protection mitigating vulnerabilities before patching
- Script-based remediation where no packaged fix exists
Patchless protection covers the window where exploitation happens
Patchless mitigation is a stopgap, not a substitute for patching

Amplifier Security
4.0Not listed
vs MobbSame
AI agents that chase security fixes with employees until remediation is confirmed.
- AI agents that engage employees directly about their own security issues
- Remediation tracking through to verified completion
- Integration with existing detection and endpoint tooling
Attacks the remediation backlog rather than adding more findings
Value depends on already having detection tooling in place

Nullify AI
4.0$67/mo
vs Mobb$47 moreSame
Autonomous AI agent that finds, prioritizes, and fixes code vulnerabilities.
- Autonomous vulnerability detection, triage, and merge-ready autofix pull requests
- Direct GitHub and Slack integration for repository assessment
- Unlimited repositories and users on the Pro tier rather than seat-based limits
Moves past detection-only scanning by opening autofix pull requests directly
No free tier, so evaluating the product means committing to the $800/year Pro plan

RunSybil
4.1Not listed
vs Mobb+0.1
Autonomous offensive security that finds exploitable vulnerabilities at development speed.
- Autonomous offensive testing rather than passive scanning
- Establishes exploitability rather than listing theoretical findings
- Noise elimination so teams triage less
Exploitability turns a backlog into an actionable priority list
Offensive testing requires careful scoping and authorisation

Snyk
4.3$25/mo
vs Mobb$5 more+0.3
Filed for a Nasdaq IPO in 2026 at a $7.4 billion valuation.
- Scans code, open-source dependencies, containers, and infrastructure-as-config
- Security built directly into developer workflows rather than added afterward
- Roughly $326M in estimated annual recurring revenue as of 2026
Developer-first design fits security scanning into existing coding workflows
Per-developer pricing can add up quickly for larger engineering organizations
