Questions & Answers

As answered by people managing PromptBrake and HackerRank.

Which are the primary technologies used for building your product?

PromptBrake's answer

PromptBrake uses Python and Flask, with SQLAlchemy for database access and Flask-Migrate/Alembic for migrations. SQLite is the default database.

The interface uses server-rendered Jinja2 templates, JavaScript, and CSS. Gunicorn serves the application, and Docker packages the deployment. Playwright supports browser-based chatbot testing.

The hosted portal integrates Firebase Authentication for identity and Stripe for subscription billing. The self-hosted runner executes security tests inside customer-controlled infrastructure.

How would you describe the primary audience of your product?

PromptBrake's answer

Teams building and releasing AI products: agents, copilots, chatbots, RAG applications, and LLM-backed APIs.

Users include founders, AI product builders, engineering teams, security teams, and agencies delivering AI applications for clients. They need to test for prompt injection, data exposure, and unsafe behavior before launch and repeat those checks as their products change.

PromptBrake is especially relevant when teams want testing and evidence to remain inside their own infrastructure.

What's the story behind your product?

PromptBrake's answer

PromptBrake addresses a practical gap: an AI product can perform well in a demo yet still expose sensitive information or follow malicious instructions.

The goal is to make security testing a repeatable part of AI product releases. Teams can test their application, inspect evidence, fix failures, and rerun checks after changes.

That focus connects PromptBrake’s free planning resources with its self-hosted runner, findings, baseline comparisons, and CI release gates: helping teams make better-informed decisions before an AI release reaches customers.

What makes your product unique?

PromptBrake's answer

PromptBrake brings automated AI security testing, evidence-backed findings, remediation guidance, baseline comparison, and CI release gates into one workflow.

Run 138 checks across 18 attack categories against your AI application using a self-hosted runner inside your infrastructure. Review failures, fix them, and retest before release.

The focus is practical: help teams turn security findings into release decisions while keeping prompts, credentials, responses, and test evidence in their own environment.

Why should a person choose your product over its competitors?

PromptBrake's answer

Choose PromptBrake for repeatable AI security testing with a maintained test suite, actionable findings, and a self-hosted deployment model.

It helps teams test before launch and after changes to prompts, models, or workflows. Evidence and remediation guidance support fixes, baseline comparison highlights regressions, and CI gates help enforce release criteria.

Evaluate it against your own application during the free trial: three scans over seven days. The paid plan is $499/month for 30 scans and one active runner license.

  • How to Stop Getting Lost in Endless Resources and Stay Focused as a Developer
    This way, you transfer what you already know (problem-solving) but only change the syntax. Platforms like Hackerrank are also great to solve the same problem in different languages and learn from other people’s solutions. - Source: dev.to / about 1 year ago
  • Pick up new languages faster this way!
    Firstly, solve some common data structure problems with it. Implement some data structures like arrays, linked lists, stacks, queues, etc. You can check common problems on LeetCode, Hackerank or some other resources. - Source: dev.to / over 2 years ago
  • Offline alternative of hackerrank.com to practice coding offline
    I don't have a consecutive internet connection and I can't keep up learning process so I started practicing in hackerrank.com I have started some challenges in python and c++ there. Thus I have no internet connection so I cannot practice... Source: almost 3 years ago
