Zapext vs WaSeller: an honest comparison of WhatsApp Web extensions

Who WaSeller is

WaSeller (waseller.com.br) is a Brazilian Chrome extension that adds a Kanban CRM, message scheduling, and an autoresponder to WhatsApp Web — the same model as Zapext: no official API, no per-message cost, everything running on the WhatsApp screen you already use. Its positioning is aggressive on price for the individual user: according to the official site (Jul/2026), the Premium license costs R$347/year or 12 card installments of R$49, and the marketing revolves around "less than R$1 a day". There is also a limited free version that works as a no-card entry point.

The deciding difference: per-user licenses vs a team account

On paper, the two tools' features look alike: visual pipeline, scheduling, automated replies. The billing model, however, follows opposite logics. WaSeller sells individual licenses — each agent needs their own. For teams, the site offers bundles of 2, 3, 5, and 6 licenses in separate checkouts, and a 4-person team pays about R$1,388/year in standalone licenses (4 × R$347, before any bundle discount; Jul/2026).

Zapext charges per account: the Plus plan costs R$79/month or R$549/year and already includes 4 users on the same number, with round-robin to distribute conversations and chat transfer between teammates. In practice:

• 1 user: WaSeller R$347/year (Jul/2026) vs Zapext Starter R$297/year — a small gap, and WaSeller still has the free version.
• 4 users: WaSeller ≈ R$1,388/year in standalone licenses (Jul/2026) vs Zapext Plus R$549/year — nearly triple.
• Flexibility: Zapext has a true monthly plan (R$39 or R$79); WaSeller works with an annual license, payable in 12 installments.

When WaSeller is the right choice

Honesty first: if you work solo and want to try a WhatsApp CRM without spending a cent, WaSeller wins this round. The free version lets you start without a card, and for 1 user the annual license is competitive — the gap to Zapext's annual Starter is R$50 a year. If a free plan is a dealbreaker criterion for you, Zapext doesn't meet it: there is no free plan, and risk-free testing happens through the 7-day money-back guarantee (if you don't like it, you get your money back).

When Zapext wins

The game flips the moment a second agent joins. Each extra WaSeller license adds hundreds of reais per year, while Zapext's Plus stays at R$549/year up to the fourth user — with the team features that matter in day-to-day multi-agent WhatsApp support: automatic conversation distribution (round-robin), chat transfer with context, and shared labels. Also weighing in Zapext's favor are the Plus webhooks (HubSpot, Bitrix24, Pipedrive, RD Station, Google Sheets), audio transcription, and local backup with encrypted data — features WaSeller's pricing page doesn't mention (Jul/2026). The extension is audited by the Chrome Web Store, where it holds a 5.0 rating with 43 reviews (verified Jul/2026), and more than 3,000 businesses use it.

How to decide

Boil the decision down to two questions. First: how many people will handle chats? Solo, the two compete head to head and WaSeller's free tier deserves a test. With 2 to 4 agents, Zapext's math works out better — by a wide margin. Second: do you want an annual or a monthly commitment? If you prefer paying month to month, only Zapext offers that.
