Everything in one place

The tools a WhatsApp-first business actually uses

Shared inbox

Every reply lands in one inbox with the 24-hour window shown. Reply with text inside the window or a template any time. Assign, close, reopen, read receipts, media.

Drip sequences

Multi-step journeys with delays, quiet hours, daily caps and stop-on-reply. Audience rules such as "new contacts only". Eight ready recipes for workshops, clinics, shops and more.

Broadcasts

Send once, send now or on a schedule. Pacing per account, retry and pause on Meta errors, an honest pre-run estimate of reach, skips and how many days it will take under your tier.

Your data, your way

CSV, Excel, Google Sheets, manual lists, an incoming webhook for forms and Zapier, and CRM APIs with presets for HubSpot, Zoho, Shopify and more. Auto-sync keeps lists fresh.

Opt-outs that stick

STOP and UNSUBSCRIBE in English and Indian languages, Meta's "stop promotions" signal and blocked numbers all go to one do-not-contact list that every send path checks.

Analytics that explain

Delivery funnel, replies, template performance and failure reasons with the fix for each. A needs-attention list tells you what to do next, not just what went wrong.

Also included
  • Keyword auto-replies and away messages
  • Tags, segments and a contacts hub
  • Admin and member roles
  • API keys and outbound webhooks
  • Slack and JSON notifications
  • Nightly backups
  • Account health monitor
  • Guided Meta setup wizard

From zero to first message

Live in an afternoon

  1. 1

    Connect your number

    Paste your WhatsApp Business Account id, phone number id and a permanent token. The setup wizard verifies each one live and registers the number with the Cloud API for you.

  2. 2

    Bring your contacts

    Upload a sheet or connect your CRM. Numbers are normalised, duplicates removed, and a preview shows exactly who will be reached.

  3. 3

    Send, then talk

    Run a broadcast or a sequence from an approved template. Replies open in the inbox, receipts arrive in real time, and opt-outs are handled before you see them.

Why self-hosted

Pay Meta. Nobody else.

Hosted WhatsApp platforms charge a markup on every message, bill per seat and keep your conversations on their servers. WhatShark runs on your own server, so the only bill is Meta's.

Questions

Frequently asked

Is this the official WhatsApp API?

Yes. WhatShark talks directly to Meta's WhatsApp Cloud API with your own Meta Business account and token. There is no third-party number in between, so you keep your green tick eligibility and quality rating.

What do I need to run it?

A WhatsApp Business Account on Meta, a phone number, and one small Linux server (a $6 cloud instance is enough). We can set it up for you, including the domain and HTTPS, in about an hour.

Will it stop me from spamming people?

It tries hard to. Marketing messages respect quiet hours and daily caps, opt-outs are enforced on every send, Meta's 24-hour marketing cooldown is honoured, and every Meta error is explained with what to do next.

Can my team use it?

Yes, with admin and member roles, assignment in the inbox, API keys for integrations and notifications to Slack when a run needs attention. No per-user fees.

What does it cost?

Meta bills you directly for messages at their published per-message rates. WhatShark adds nothing per message. Message us on WhatsApp for setup and support options.
