Ship AI features without shipping vulnerabilities. PromptBrake is a pre-release security testing platform for LLM-powered APIs โ€” point it at your endpoint and run repeatable scans for prompt injection, data leaks, unsafe tool use, and output bypasses, mapped to the OWASP LLM Top 10.

Each finding includes evidence logs and remediation guidance, so you know exactly what to fix. Compare runs to catch regressions, and plug the same checks into CI to gate risky releases.

Works with OpenAI, Claude, Gemini, and custom LLM-backed endpoints. Also includes free tools such as an LLM security checklist, a prompt injection payload generator, and an OWASP LLM test case mapper to help teams validate their setup early.

    For users who are not familiar with web development technologies, customizing and extending Hyper might be challenging.
  • Stability
    Occasional bugs and crashes can occur, especially when using numerous plugins or custom configurations.
  • Native Feature Gaps
    Some of the features available in native terminal emulators might be missing or less optimized in Hyper.

Analysis of Hyper

Overall verdict

  • Hyper is a good choice for users who value customization and a visually appealing interface over performance. While it may not match the speed and efficiency of native terminal applications, its flexibility and design appeal to those who are comfortable with and prefer Electron-based applications.

Why this product is good

  • Hyper is an electron-based terminal that is highly customizable, allowing users to enhance its functionality through plugins and themes. It's built with web technologies, making it easy for developers familiar with JavaScript, HTML, and CSS to contribute and modify. This enables a rich ecosystem of community contributions, offering users a wide variety of enhancements to tailor the terminal experience to their needs.

Recommended for

  • Developers who prefer a customizable terminal environment
  • Users who enjoy experimenting with plugins and themes
  • Individuals who prioritize design and aesthetics in their tooling

Analysis of PromptBrake

Overall verdict

  • I don't have verified information about PromptBrake (promptbrake.com), so I can't confirm whether it's a good product. Please verify its features, reviews, and reputation directly before making a decision.

Why this product is good

  • I have no reliable data on PromptBrake's actual features or performance, so any specific claims would be unverified
  • The name suggests it may be a prompt management or AI safety/moderation tool, but this is only speculation and should be confirmed
  • Independent user reviews and third-party evaluations, if available, would offer more trustworthy insight than assumptions
  • Checking the official website, documentation, pricing, and security/privacy policies is the best way to judge its quality

Recommended for

  • Users who first independently verify the tool's features and legitimacy
  • Teams evaluating AI prompt management or moderation tools who can run a trial or demo
  • Anyone who reads current user reviews and compares alternatives before committing

Questions & Answers

As answered by people managing Hyper and PromptBrake.

Why should a person choose your product over its competitors?

PromptBrake's answer:

Choose PromptBrake when you want a security check, not a security project. Open-source tools like Promptfoo and Garak are powerful, but expect you to design your own test suite, write probes, and interpret raw output โ€” that's a week of setup before your first useful result. Manual AI pentests deliver depth but cost $5,000โ€“$20,000 per audit and run at best quarterly. PromptBrake fits the gap: an opinionated, repeatable suite you can run before every release, with results your engineers can act on without a security background. If your team ships AI features faster than a security calendar can keep up, that's the workflow PromptBrake is built for.

Which are the primary technologies used for building your product?

PromptBrake's answer:

Backend: Python with Flask, SQLAlchemy, Flask-Migrate (Alembic), and Gunicorn. Database: SQLite. Auth and identity: Firebase Authentication. Payments: Stripe. Frontend: server-rendered Jinja2 templates with vanilla JavaScript and CSS โ€” no SPA framework. Infrastructure: AWS (EC2), with Cloudflare in front for WAF and CDN.

What makes your product unique?

PromptBrake's answer:

PromptBrake is the only LLM API security scanner built as a product, not a framework. While open-source tools like Promptfoo and Garak give you a flexible harness for building your own red-team workflow, PromptBrake gives you an opinionated 12-test suite (60+ real-world attack scenarios, OWASP LLM Top 10-aligned) that runs against your endpoint with zero configuration. Every finding comes with PASS/WARN/FAIL verdicts, evidence logs, and concrete remediation steps โ€” so engineers know exactly what broke and how to fix it. Compare any two runs to track regressions and fixes between releases, and drop the same scans into CI as a release gate. Works with OpenAI, Claude, Gemini, and custom LLM-backed endpoints. No security team, no harness setup, no agent install โ€” point it at your endpoint and ship with confidence.

How would you describe the primary audience of your product?

PromptBrake's answer:

Engineering teams shipping LLM-powered APIs who are accountable for security but don't have a dedicated security team. That includes startup engineers wiring an AI feature into production, platform teams adding LLM endpoints to existing apps, and solo builders who need a credible security check before launch. The common thread: they own an AI endpoint, they're shipping fast, and they need a repeatable answer to "is this safe to release?" without hiring a pentester or building a red-team harness from scratch.

What's the story behind your product?

PromptBrake's answer:

If you've shipped an LLM-powered API, you've probably had this moment: someone asks, "Is it secure?" and you don't know where to start. OWASP publishes a Top 10 for LLMs. Headlines warn about prompt injection, jailbreaks, data leaks, and tool abuse. Blog posts disagree on what to test and how to test it. Open-source frameworks hand you a toolkit and assume you already know what to do with it. Manual pentests cost probably $5,000 to $20,000 and take weeks to schedule. Most engineers shipping AI features aren't security researchers โ€” they need a credible answer before the next release goes out. That's the gap PromptBrake was built for. One opinionated suite. Twelve tests covering what actually matters. PASS/WARN/FAIL results with evidence and remediation in plain language. Point it at your endpoint, see what's broken, fix it, ship. Security testing shouldn't require becoming a security expert first.
