Evaligo is a visual no-code platform for building AI workflows, apps, and automations. It combines prompt engineering, workflow building, and app creation in one platform, allowing you to test prompts, create AI agents, and deploy APIs instantly.

Is Evaligo free to use?

Yes, Evaligo offers a free tier that lets you build and deploy AI workflows without a credit card. The free tier includes generous limits for personal projects and testing.

Do I need to know how to code to use Evaligo?

No coding is required. Evaligo uses a visual drag-and-drop interface where you connect nodes to build workflows. However, developers can also use custom code nodes for advanced use cases.

What can I build with Evaligo?

You can build AI agents, chatbots, content generators, data pipelines, automation workflows, and AI-powered apps. Common use cases include marketing automation, customer support bots, content creation, and data processing.

A/B testing for AI models, prompts and flows

Find out which AI model wins on your data

Run the same prompt or flow on several AI models, score every output with blind AI judges, and compare quality, cost and speed side by side. Then deploy the winner as an API.

Evaligo A/B test scoreboard: six AI models compared on the same 30 inputs, scored by three blind judges, with cost and speed per output

A real Evaligo experiment: six models, the same 30 inputs, three blind judges. Read the full write-up.

Compare models, prompts and flows on the same inputs

Any model as a variant, including open source

Pick the models you want to compare: OpenAI, Google, Anthropic, and open-source models such as DeepSeek, MiniMax, Kimi and Qwen through one OpenRouter key. Each variant runs the same flow on the same inputs; only the model, prompt or reasoning setting changes.

Any model as a variant, including open source - Evaligo A/B testing

Test on your own data, or generate it

Run every variant over a dataset of real inputs. If you have none yet, Evaligo generates a realistic test set from a one-line description, so a 30-sample comparison is ready in minutes.

Judge every output blind

Rubrics, not vibes

Write the criteria once: what a good output must do, and what costs points. AI judges score every output against the rubric without knowing which variant produced it, and record a one-line reason per score.

Judge panels from several vendors

Use one judge model or a panel of three from different vendors, averaged. Per-judge scores stay visible, so you can see where the judges agree and where they do not.

Repeat runs, on purpose

Model output and judging both vary between runs. Re-run an experiment with one click and compare runs side by side before you decide.

Quality, cost and speed per output

Every experiment ends in one table: score, flawless outputs, cost per output and latency for each variant, with a score distribution per sample. Export it as a PDF report.

Promote the winning variant

Make the winning model, prompt or flow the live version with one click. The flow keeps its inputs, outputs and API endpoint.

Deploy as a production API

Any flow deploys as a REST API with authentication, documentation and code examples. Batch processing and monitoring are built in.

Built on a visual flow builder

Describe the flow in one sentence and Evaligo builds it: prompts, web scraping, data extraction, tools and agents as connected nodes. Edit visually or by instruction.

From question to scoreboard in an afternoon

Build the flow, test it across models on your data, and ship the version that scores best. The six-model benchmark on this page cost $3.18 to run.

Step 01

Build

Describe the flow in one sentence, or paste the prompt you already use. Evaligo builds the flow as connected nodes; edit it visually or by instruction.

Step 02

Test

Add variants: other models, other prompts, other reasoning settings. Run them all on the same dataset. Blind AI judges score every output against your rubric.
