In their own words, as submitted to SaaSHub.


LeakWatch finds the API keys you leaked in public commits and in your repositories, then tests each one against its provider : so you know which are still live, not just which matched a pattern. Free lookup by username, continuous monitoring for your repos, and a REST API for the rest.

As answered by people managing LeakWatch.net and Diffyn.
LeakWatch.net's answer
Detection is the easy part. LeakWatch is built around what happens after.
Three things set it apart: 1. Validity, not pattern matching. Finding a string shaped like an AWS key is trivial : gitleaks and TruffleHog do it for free. LeakWatch takes the extra step : it checks the credential against the provider to see if it's still active. Today that covers 25 providers (AWS, Stripe, GitHub, OpenAI, Anthropic, Azure, Google, Discord, npm, database URIs, private keys…). A dead key is noise; a live key is an incident. 2. Three forges, not just GitHub. GitHub, GitLab and Codeberg, monitored continuously: public repos and, via the GitHub App, private ones. Most tools stop at GitHub. 3. Full git history, not just HEAD. Secrets are usually "fixed" by a later commit that deletes the line, which leaves the key perfectly readable in history and perfectly invisible to a HEAD-only scan. LeakWatch replays the whole history.
Plus: a public API, a README badge, per-provider revocation steps, and a free scan with no account. €4.99/month.
Diffyn's answer:
Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.
LeakWatch.net's answer
Because the leak that hurts you usually isn't in your repo. It's in a fork, a contributor's personal account, or a throwaway snippet. Every other option scans code you already control : GitHub scans repos hosted there, the CLIs scan clones you run them on. LeakWatch watches the perimeter around you, on GitHub, GitLab and Codeberg, with no install and no per-seat pricing.
Diffyn's answer:
Diffyn is the platform that specializes on both change management and multi-model analysis.

Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
