## How we research

We read what long-term users report in public threads and review sites, check vendor documentation and pricing pages, and verify prices with each vendor before we write a verdict.

### Where the evidence comes from

We read public discussions — Reddit threads, Hacker News comments, and reviews on G2, Capterra and Trustpilot — and group what people repeatedly say into themes. Every quote we publish is a verbatim excerpt and links to the thread it came from, so you can read it in context and disagree with our reading of it.

We do not publish a claim we cannot link to a source. Research that has not been checked by a person is not published at all.

### How we rank

Rankings reflect what the evidence supports for a specific kind of buyer. Each page says who a tool suits and who it does not, and a position changes when the evidence does.

### How we make money

We may earn a commission when you buy through links on this page. It never affects our rankings. When you buy through one of our links, the price you pay is unchanged.

### Corrections

Pricing and features change. Each tool page shows the date we last checked. If something here is wrong, [tell us](/contact) and we will fix it and say that we did.
