    How the Ranking Works

    What it weighs

    • We score each platform 1 to 5 on the six priorities. Your sliders set how much each one counts.
    • The job you pick scales the result: a platform built for that job keeps its full score, one that isn't drops sharply.
    • Self-hosting leads the list because it decides where your data can live.
    • Hide any platform and the ranking recalculates without it.

    Sources

    • Every fact in the table links to the vendor's pricing, documentation or trust page.
    • Prices are in US dollars unless the vendor lists another currency.
    • Checked 4 October 2026. Plans and prices change, so confirm them with the vendor before you buy.

    FAQ

    Questions About This Tool

    Is this comparison neutral?

    We are an n8n Select Partner, and n8n carries a Partner tag on the page. Every fact links to the vendor's own pricing, documentation or trust page. The map positions and scores are our judgment, and the ranking puts another platform first whenever your answers fit it better.

    What is the difference between deterministic AI workflows and AI agents?

    A deterministic workflow runs the same defined steps every time, with AI inside some of those steps, so you can test and audit every run. An agent picks its own next step from a goal and the tools you give it. That suits open-ended work such as researching leads, but every run can differ.

    Which platforms can we self-host?

    n8n and Sim. n8n's Community Edition is free to self-host and its Enterprise plan supports air-gapped installs. Sim is open source under the Apache 2.0 license. Self-hosting lets you run either one on your own servers or in any US cloud region. Microsoft Foundry's Standard setup keeps agent data in your own Azure resources.

    How current are the prices?

    We check every fact against the vendor's own pages once a month, and the date of the last check sits under the table. Most enterprise plans are quoted on request, so confirm the price with the vendor before you buy.
