Pricing, capabilities and platforms side by side. Prices are as of the "Pricing checked" date in the table.

Catcher
You describe tests in plain English, and Catcher's LLM-powered planner executes them in a real browser — no script authoring, no Selenium boilerplate. The vision-based fallback handles dynamic UIs where element selectors break, which is where most scripted test frameworks quietly start failing your CI. Because you supply the API key directly, LLM costs land on your own account — nothing is proxied through a vendor margin. The ceiling arrives when you need a test management dashboard, CI pipeline integrations, or a shared test artifact store across a team: the repo describes none of those, and you are building that infrastructure yourself.

Maced AI
Maced deploys AI agents that crawl, fuzz, and attempt exploitation across your web apps, APIs, source code, and cloud infrastructure — then deliver audit-grade reports with proof-of-exploit payloads and merge-ready fix PRs. Every finding is auto-validated before it surfaces, which means triage queues shrink instead of growing. The continuous monitoring model means your attack surface is tested on every deploy, not just once a quarter. The ceiling shows up when your environment demands the kind of adversarial creativity a seasoned human tester brings to a novel business-logic flaw — agents that follow a structured probe loop will miss what only lateral thinking finds. Teams with that requirement use Maced for baseline and point a human at what the agents flag as high-severity.
