SELF-CHECKS
Free tools for founders
Our free tools for founders check where an AI-built app might break, compare a fractional CTO with a hire and show what your MVP needs first. Each one runs in your browser and shows its assumptions.
3 SELF-CHECKS
The drawing shows our three tools running in your browser and, under it, answers that never reach our servers, with analytics, if on, seeing only the tool's name.
HOW TO CHOOSE
Which of our free tools for founders to use
Three tools, three decisions.
- You built your app with an AI tool and want to know where it may break. Start with the Vibe coding risk check for AI-built apps. Ten questions show where the risk sits across security, data, payments and operations.
- You need senior technical leadership and want to compare costs. Use the Fractional CTO cost calculator to set the hours and rate you were quoted against a full-time salary, monthly and yearly.
- You have a feature list and need to decide what to build first. Open the MVP scope planner to sort features into Build first, Later and Cut, and see the assumptions behind the estimate.
These founder self-checks give you a starting point, not a verdict. Each one says what it counts, where its numbers come from and when they were last checked, and none of them asks for your email.
