We file it under AI app builders, the category of tools to build an app or site without coding, and it also overlaps with website builders. The category lists 12 verified tools on this site.
The publisher is RocketSocial SASU, based in France.
Who is it for?
It is mostly useful to these profiles: small business owners, freelancers, and developers. The need it covers is simple to state: build an app or site without coding.
Capacity is a good candidate if:
- you want to try before paying
The best test is a concrete case from your daily work: if the tool does not beat your current method within a week, move on to an alternative.
How much does Capacity cost?
Pricing model: freemium (limited free use, then paid). A free plan is offered, usually limited in volume or features.
The first paid plan costs $25 per month (Starter, 100 credits per month; top-ups offered separately from USD 9 for 10 credits), according to the pricing page, checked on October 24, 2026.
Per month, that is more expensive than the category median ($20 per month, based on tools with a published price).
To estimate what the same work would cost done directly with an AI model, use our API price calculator. Prices change often: always check the official site before subscribing.
Data and privacy
The publisher does not clearly state where data is hosted. Assume your content may leave your region.
For professional use, check that a data processing agreement (DPA) is offered, and do not send customers' personal data or confidential documents without one.
Exporting your content: yes (details on the official site). Being able to get your data back makes switching tools easier later.
Three habits apply to every AI tool:
- turn off the use of your content for training if the option exists
- use a work account separate from your personal account
- review everything the tool produces before publishing or sending it
Platforms, languages and API
Capacity runs on: web browser, Windows, and macOS.
Interface languages: English and German.
