What is Evaligo?
Evaligo lets people evaluating models compare responses and assess them against custom criteria. It also provides visual workflow building and allows a workflow to be published as an API.
According to its documentation, Evaligo lets you:
- compare responses from several models
- evaluate responses using custom criteria
- build workflows visually
- publish a workflow as an API
We file it under LLMOps and observability, the category of tools to evaluate, monitor and debug AI apps, and it also overlaps with workflow automation and aI agent builders. The category lists 18 verified tools on this site.
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.
Evaligo is a good candidate if:
- you want to try before paying
- you plan to connect it to your tools or automations through its API
Before deciding, run a trial on a real task and measure the time saved: it is the only criterion that really counts.
How much does Evaligo 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 $7 per month (Pro, 10,000 credits per month), according to the pricing page, checked on October 24, 2026.
Per month, that is cheaper than the category median ($49 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
Evaligo 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.
How we scored it
Our 48/100 score does not judge output quality: it measures what can be publicly verified about access to the tool, its openness and how far the publisher can be trusted.
| Criterion | Points | What counts |
|---|---|---|
| Access | 25/30 | free tier, published price, French interface |
| Openness | 20/30 | API, data export, open code |
| Trust | 3/40 | identified publisher, declared hosting, age, presence in reference lists |
