We file it under LLMOps and observability, the category of tools to evaluate, monitor and debug AI apps, and it also overlaps with data science and machine learning and aI agent builders. The category lists 18 verified tools on this site.
The publisher is Overmind Technology Limited, based in United Kingdom.
Who is it for?
It is mostly useful to these profiles: developers and data analysts. The need it covers is simple to state: evaluate, monitor and debug AI apps.
Overmind is a good candidate if:
- you want to try before paying
- you plan to connect it to your tools or automations through its API
- you must keep your data in Europe or on your own machine
- you want to read the code or host it yourself
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 Overmind cost?
Pricing model: open source (public code). A free plan is offered, usually limited in volume or features.
The first paid plan costs $120 per month (Pro, hosted platform), according to the pricing page, checked on October 24, 2026.
Per month, that is more expensive than the category median ($49 per month, based on tools with a published price).

Data and privacy
According to its privacy policy, data is processed in the European Union.
Hosting in the European Union makes GDPR compliance easier, without exempting you from reading the terms of use.
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
Overmind runs on: web browser and API.
Interface languages: English.
A public API lets you call it from your own programs or an automation tool, and plug it into an AI agent.
The source code is public: overmind-coreovermind-core/overmind.
