PromptBrake pricing guide details
Pricing Overview
PromptBrake sells one plan. PromptBrake Enterprise is $499/month, billed month-to-month, and includes 30 scans per billing period and one active Enterprise Runner license. There is no cheaper tier and no annual commitment; renewal and cancellation are managed from the account dashboard.
Before that there is a free trial, and it is a real one rather than a demo request. Account creation costs nothing, and a trial license issued from the dashboard gives 3 scans over 7 days with no payment and no approval step. That is enough to point the runner at a staging endpoint and see what the checks report on your own application, which is the only way to judge whether the paid plan is worth $499 to you.
This structure replaced an earlier two-tier arrangement. If you are working from a comparison written before September 2026 that describes Scout and Pro plans at lower monthly prices, those plans no longer exist.
Plan Comparison
There is one plan, so the comparison that matters is what the $499 covers against what it does not.
| PromptBrake Enterprise | Free trial license | |
|---|---|---|
| Price | $499/month, month-to-month | $0 |
| Scans | 30 per billing period | 3 over 7 days |
| Runner license | One active Enterprise Runner | Included for the trial |
| Checks | 138 across 18 attack categories | Same checks |
| Reporting | Findings with evidence, business impact and remediation guidance | Same |
| Evidence exports and Baseline Diff | Yes | Yes |
| CI release gates | Yes | Yes |
| Payment | Card on file | None required |
The quota is the constraint to plan around. Manual and CI-triggered scans draw on the same 30, and a re-run after a fix consumes another one, so a team that gates every pull request will exhaust a month faster than a team that scans at release. The quota resets when the subscription renews and does not roll over, and one runner license is active at a time.
Hidden Costs and Considerations
The subscription is the whole vendor charge, which is unusual in security tooling, but three costs sit outside it.
The first is the infrastructure the runner occupies. PromptBrake executes locally: you deploy the Enterprise Runner with Docker inside your own environment, near the target you want to test, and prompts, credentials, responses and evidence stay there. Only license checks and quota usage reach PromptBrake. That is a genuine privacy property and it means you supply and pay for the host.
The second is the model traffic the scans generate. A scan drives real requests at your chatbot, agent or LLM API, and whoever bills that endpoint bills you for them. With 138 checks across 18 categories, a full scan is not a trivial number of calls, and against a metered commercial model the cost is small but not zero.
The third is the work after the finding. The product reports the triggering input, the response, the business impact and remediation guidance; fixing the behaviour and re-running is engineering time, and the re-run spends quota. Teams that treat a scan as a release gate should budget for both.
Cost Estimates by Team Size
Because pricing is a flat subscription rather than per seat, headcount does not change the bill. What changes is whether 30 scans a month is enough.
| How you use it | Scans per month | Plan cost | Fits the quota? |
|---|---|---|---|
| Pre-release check on one product | 4-8 | $499/month | Comfortably |
| Weekly scan plus fix re-runs | 8-16 | $499/month | Yes |
| CI gate on every release branch | 20-30 | $499/month | At the limit |
| CI gate on every pull request | 30+ | $499/month | No — expect to exceed it |
The honest read is that PromptBrake is priced for deliberate testing rather than continuous scanning. If your intended pattern is a gate on every pull request, work out your real merge rate before committing, because the quota, not the price, is what will bite.
How PromptBrake Pricing Compares
It is not really competing with general security platforms on price, and the comparison is more useful for showing what a narrow product costs against broad ones.
| Tool | Model | Entry price | Scope |
|---|---|---|---|
| PromptBrake | Flat subscription | $499/month | LLM and agent endpoint testing |
| Snyk | Freemium, per developer | Free tier, then $25/developer/month | Code, dependencies, containers, IaC |
| Auth0 | Freemium, per active user | Free to 25,000 MAU, Essentials from $35/month | Identity and access |
| Wiz | Enterprise quote | Quoted | Cloud posture across workloads |
Two things follow. PromptBrake costs more per month than a small Snyk team plan and covers a category Snyk does not touch, so for a team shipping AI features they are complements rather than alternatives. And against a cloud security platform quoted in tens of thousands a year, $499/month is a rounding error — which is the argument for buying it as an addition rather than a replacement.
The case against is the quota rather than the price. A flat $499 with a hard scan ceiling suits a team testing at release and frustrates one testing continuously, and there is no published higher tier to grow into.
