Easy Flow Builder is a focused WhatsApp flow builder at €50 per month with no per-user fees. Trengo, Saysimple, and Watermelon are broader customer communication platforms with per-user licenses and pricing on request; Twilio is infrastructure for developers. If you're after a full omnichannel inbox, one of those platforms makes more sense. If you want to automate WhatsApp without a developer and without license costs that keep climbing, we're the simpler choice.

See the comparison →What we deliberately don't go along with
- Price on request: our price is on the site, €50 per month
- Per-user licenses: your whole team joins in at no extra cost
- Mandatory implementation projects: you build your first flow yourself in an hour
- Extra channels you don't use: we do WhatsApp, and we do it well
Our method
We base comparisons on publicly available information from the vendors themselves, with the date we checked it. We don't quote other companies' prices when they aren't public, and we always say where the other one is stronger. Spot a mistake? let us know and we'll correct it.
Frequently asked questions
Why isn't the competition's price in the tables?
Because it isn't public. Trengo, Saysimple, and Watermelon don't publish a full price list. We'd rather say nothing than something we can't back up.
Are these comparisons up to date?
They were checked on July 28, 2026 and carry a visible date. Platforms change; if in doubt, check the current situation with the vendor.
