MVP tools are the builders and services startups use to put a minimum viable product in front of real users quickly. The right one depends on the assumption you are testing: a landing page tests demand, a prototype tests usability, and a no-code app tests whether people come back.

No-code web app builder
Visual programming platform for building fully functional web and mobile apps without code, a staple for MVPs.
AI app builder
AI tool that generates full-stack web apps from chat prompts, letting non-developers stand up MVPs in hours.
Open-source design & prototyping
Open-source, web-based design and prototyping tool built on open standards, self-hostable.
The basics
MVP tools help a team build the smallest test of an idea. They range from landing page builders and no-code app builders to design and prototyping tools.
Eric Ries describes the MVP as the start of the build-measure-learn loop. Its job is learning as quickly as possible, not launching a finished product.
A smoke test measures interest before the product exists. A concierge MVP delivers the service by hand. A "Wizard of Oz" MVP looks automated but runs on manual work.
Many first tests need no build at all. Interviews, a paper prototype or a simple form can answer the riskiest question.
MVP tools earn their place when you must observe real behavior, such as sign-ups, payments or repeat use. Check whether you can export your work if the test succeeds.
The routine it supports
How the listed tools are priced
Start from the riskiest assumption, not the feature list. Write it down, decide what customer action would prove it true or false, and set that threshold before you build anything. A lean canvas is a quick way to find the riskiest box.
Then choose the cheapest test that produces that action. Often that is a landing page or a manual service rather than software. Launch to people in your target segment, measure what they do, and decide whether to persevere or pivot. The minimum viable product guide covers each step in more depth.
No-code MVP tools let a founder build web apps, forms, automations and databases without writing code. They make it cheap to change direction, which is what an early MVP needs most.
Custom development makes sense when the test depends on something no-code tools cannot do, such as a new algorithm, deep hardware integration or strict data rules. Either way, check what happens if the test succeeds: whether you can export data and logic, or will need to rebuild.
Eric Ries describes several early MVPs in The Lean Startup. Dropbox tested demand with a short video that showed how the product would work, before the product was ready for most users. Zappos began by photographing shoes in local stores and buying them only when an order came in.
Both tests answered one question each: would people want this, and would they buy shoes online? Neither needed a finished product. The lean startup guide places these examples in the wider method.
Buying guide
Who it's for: Founders, product managers and innovation teams who want to test demand and usability before investing in full development.
Speed to first test
From idea to something a real customer can see quickly, so you can run many tests.
Built-in measurement
Sign-ups, clicks and conversion tracked without extra setup.
Easy iteration
Change copy, layout or flow quickly between experiments.
A path forward
Know what happens if the test succeeds: export, scale or rebuild.
