Pricing Overview
PromptBrake offers two straightforward monthly plans for automated LLM security testing: Scout at $79/month and Pro at $149/month. There are no annual contracts or hidden commitments — both plans are month-to-month. Both tiers include free trial scans so you can evaluate the platform before committing. Scout covers the essentials with 18 full 12-test scans per month, while Pro unlocks CI/CD integration, exportable reports, and release gating for teams that ship frequently. We appreciate the simplicity here — no enterprise-only pricing walls or "contact sales" gates. You pick a plan and start scanning in minutes.
Plan Comparison
PromptBrake keeps its plan structure lean with just two tiers. Here is the full breakdown:
| Feature | Scout ($79/mo) | Pro ($149/mo) |
|---|---|---|
| Monthly scans | 18 | 25 |
| Security tests per scan | 12 (full profile) | 12 (full profile) |
| Attack prompts per scan | 60+ | 60+ |
| PASS/WARN/FAIL verdicts | Yes | Yes |
| Evidence logs for failures | Yes | Yes |
| App results dashboard | Yes | Yes |
| JSON + PDF report exports | No | Yes |
| CI/CD API keys | No | Yes |
| Release gating integration | No | Yes |
| OWASP-aligned advanced tests | No | Yes |
| Free trial scans | Yes | 5 free scans |
The core scanning engine is identical across both plans — every scan runs the same 60+ attack prompts across all 12 security checks. The real difference is workflow integration. Scout is built for teams running manual security checks before deployments. Pro is built for teams that want automated security gates inside their CI/CD pipeline. If you deploy weekly or more frequently, the Pro tier pays for itself by catching vulnerabilities before they hit production without manual intervention.
Hidden Costs and Considerations
Watch for these cost factors that are not obvious on the pricing page:
- Scan limits are hard caps. At 18 or 25 scans per month, teams with multiple endpoints or frequent deploys could burn through their allocation quickly. There is no overage pricing disclosed — you simply wait until next month.
- API costs are on you. Each scan sends 60+ prompts to your LLM endpoint. With GPT-4 or Claude, that is real token spend on your API bill.
- No free tier exists. Unlike some competitors, there is no permanent free plan — only trial scans to get started.
Cost Estimates by Team Size
| Team Size | Recommended Plan | Monthly Cost | Cost per Scan |
|---|---|---|---|
| Solo developer (1-2 endpoints) | Scout | $79/mo | ~$4.39/scan |
| Small team (3-5 endpoints) | Pro | $149/mo | ~$5.96/scan |
| Growing team (5-10 endpoints) | Pro (may need multiple) | $149+/mo | Varies |
For a solo developer shipping one or two AI features, Scout's 18 scans per month is generous — that is roughly 4 scans per week. A small team juggling multiple endpoints will want Pro for CI/CD integration and the extra 7 scans per month. Teams with more than 10 active endpoints will likely need to contact PromptBrake about higher-volume arrangements, since 25 scans spread across many endpoints leaves little room for re-testing after fixes.
How PromptBrake Pricing Compares
PromptBrake occupies a niche — dedicated LLM security scanning — so direct comparisons are imperfect, but here is how it stacks up against security-adjacent tools in the AI tooling space:
| Tool | Starting Price | Model | Focus |
|---|---|---|---|
| PromptBrake | $79/mo | Paid (monthly) | LLM endpoint security testing |
| CodeWatchdog | $9/mo (free tier available) | Freemium | Code security analysis |
| Vibio | Free ($29/mo for paid) | Free / Paid | AI security tooling |
| Didit v3 | $0.03/user | Usage-based | Identity verification |
PromptBrake is the most expensive entry point at $79/month, but it is also the only tool here purpose-built for LLM endpoint vulnerability scanning. CodeWatchdog and Vibio offer broader security coverage at lower price points, but they do not match PromptBrake's depth in prompt injection and data leak testing. We think $79/month is reasonable for teams whose AI endpoints handle sensitive data — a single prompt injection incident in production would cost far more than a year of PromptBrake scans.
