How we grade them
| 2.2GPATrengoFair | 2.4GPAZendeskFair | |
|---|---|---|
| Value for money | DBoost is €299 a month billed yearly (€349 monthly) for up to 10 users, so a team of five pays about €60 a head, well above the dearest tenth of help desks at $39. On your own, it's the full €299. It does include 6,000 conversations a year and the WhatsApp API. | DSupport Team is $19 an agent billed yearly, a little under this category's middle, but it's email tickets only. Chat, phone and a help center start on Suite Team at $55 an agent, above the dearest tenth of help desks, and extra AI resolutions are $1.50 to $2 each. |
| Free plan and trial | CA 7-day free trial with no card needed, which is short for a tool this costly. There's no free plan after it. | CA 14-day free trial of Suite Professional with Copilot, which shows you the top of the range. There's no free plan, and the listing doesn't say whether the trial needs a card. Funded startups can get 6 months free. |
| Features | BOne inbox for email, WhatsApp, Instagram, Messenger, TikTok, chat and SMS, the HelpMate AI agent, a help center, multi-step automations and links to stores, CRMs and booking sites. Phone calling is an add-on, but the job is covered. | BTicketing across email, chat, social and phone, AI agents on every plan, help centers in 40+ languages with forums, voice numbers in 75+ countries, an IVR and reports you ask for in plain words. The whole job is covered. |
| Ease of use | CNo store rating on record. You connect the WhatsApp Business API and each other channel, then set up AI flows, and the AI Journeys part is still marked as a beta. | B4.5 from 4,219 App Store ratings for the agent app. Prebuilt dashboards and pre-written replies come on every plan, but routing, triggers and automations take setting up. |
| Platforms and integrations | BIt runs in a browser only, with no app for phones or computers, though you can add it to a phone's home screen. The connections help: Shopify, WooCommerce, Magento, HubSpot, Salesforce, Pipedrive, Booking.com and Airbnb, plus an API. | BWeb, iPhone and Android, with WhatsApp, Facebook, Instagram, X, Slack, WeChat and LINE as channels, and an API. No desktop app, which keeps it off an A. |
| Best for | WhatsApp-heavy service teams in Europe | support teams handling email, chat and phone |
