WATI, AiSensy, Gallabox, Interakt, and DoubleTick are the WhatsApp-first family — the Business Solution Providers (BSPs) an India or Southeast Asia SMB shortlists when the buying question is "who runs our WhatsApp number." All five sell the same shape: a shared team inbox and template tooling on Meta's WhatsApp Business Platform, localized for the region — INR and SEA pricing, UPI-friendly billing, sales-assisted or self-serve onboarding into embedded signup. This post names all five vendors (our WhatsApp Business API guide deliberately names none), scores the archetype against an omnichannel platform, keeps the reach where WhatsApp-only wins, and marks the boundary where the single channel stops being the whole plan.
The five vendors, read straight
Read the published surfaces at face value, because these vendors are more alike than their sales positioning suggests:
- WATI (Clare.ai) — the shared-inbox-and-automation member: a team inbox on the Business API, a no-code chatbot builder, broadcast campaigns, and a subscription plan aimed at SMB and mid-market teams across Asia. API access rides on top of the GUI product; the inbox is the center of gravity.
- AiSensy — the broadcast-and-template-tooling member: campaign sending, template creation and tracking, forms and ads tooling on WhatsApp, priced in INR plans targeted at Indian D2C and SMB marketers. The product is oriented to the marketing motion first; programmatic access is a secondary surface.
- Gallabox — the Chennai-based shared-inbox member, positioned for SMB sales and support teams: no-code bots, inbox, and commerce-adjacent tooling (catalogs, payment prompts) inside Indian-market price points.
- Interakt (Jio Haptik) — the commerce-adjacent member inside the Haptik/Jio stack: the WhatsApp inbox plus CRM-style contact management, catalog and commerce tooling, and notification campaigns for Indian SMB merchants.
- DoubleTick — the sales-team-inbox member: WhatsApp for sales teams plugging into mainstream CRMs, with broadcasting and an INR plan structure aimed at Indian SMB sales organizations.
All five are real products that hold their niche, and the shared boundary is identical: the product is one channel. WhatsApp is the inbox, the campaign surface, and the integration target. None of the five publishes SMS, RCS, email, or voice as first-class channels on the same consent record, and none ships a native AI-agent runtime — the chatbot builders are flow bots scoped to WhatsApp, not agents that also answer calls or read a cross-channel customer profile.
The BLUF table
Vendor-by-vendor on the rows a buyer actually compares, from each vendor's published scope, against Devotel Orbit's published omnichannel surface:
| Decision row | WATI | AiSensy | Gallabox | Interakt | DoubleTick | Devotel Orbit |
|---|---|---|---|---|---|---|
| Shared team inbox on WhatsApp | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ |
| WhatsApp flow / bot builder | ✓ no-code flow bots | ✓ template-led | ✓ no-code flow bots | ✓ no-code flow bots | ✓ flow bots | ✓ plus native AI agents on voice + messaging |
| Pricing model | INR subscription tiers + Meta's conversation charges | INR subscription tiers + Meta's conversation charges | INR subscription tiers + Meta's conversation charges | INR subscription tiers + Meta's conversation charges | INR subscription tiers + Meta's conversation charges | Pay-as-you-go per message on the published Pricing page |
| Channels beyond WhatsApp (SMS, RCS, email, voice, video) | ✗ | ✗ | ✗ | ✗ | ✗ | ✓ one account, one consent record |
| Native AI agents (voice + messaging) | ✗ | ✗ | ✗ | ✗ | ✗ | ✓ |
| Developer API access | ◐ secondary to the GUI | ◐ secondary to the GUI | ◐ secondary to the GUI | ◐ secondary to the GUI | ◐ secondary to the GUI | ✓ first-class, one API across channels |
Two cautions on the ✗ and ◐ rows. A ✗ means the capability is absent from the vendor's published public scope at the time of writing — not that it fails at it. An ◐ means an API exists but the vendor's own product framing is the admin-console-first version of the channel; the developer surface is documented behind the product, not as the product.
Where the archetypes genuinely diverge
Three rows deserve the long version, because they are where a WhatsApp-first BSP and an omnichannel platform stop being variants of one product and become different products:
- Template tooling versus programmatic API. AiSensy and the inbox-first members orient the product to broadcast and template management inside a console — a marketer operating a campaign calendar is the first user, and REST access is the escape hatch behind it. Orbit ships the WhatsApp channel as a first-class developer surface — the WhatsApp Business API guide walks the same conversations, templates, and 24-hour window mechanics as an API contract — and the console rides on the API rather than the reverse. A team with no developers buys the first shape on purpose; a team whose product itself sends messages cannot.
- India/SEA SMB pricing model. All five BSPs run subscription tiers in INR or local SEA equivalents, with Meta's per-conversation charges passed through on top — a flat plan good for the team whose monthly volume is stable and predictable. Orbit publishes pay-as-you-go per-message pricing on the Pricing page with no platform subscription over the conversation rate, which prices the team whose volume is spiky, seasonal, or just starting. Read the WhatsApp pricing shift post for what per-user message pricing does to a campaign budget before picking the model that matches your send pattern.
- Single-channel lock-in versus the omnichannel wallet. Every one of the five BSPs ends at WhatsApp's boundary. The moment the plan adds an SMS fallback where WhatsApp penetration is thin, an RCS campaign to Android handsets, an AI voice agent answering on the same customer profile, or email as the audit-trail channel, the WhatsApp-first account stops being the whole stack and becomes one vendor in a collage. Orbit's account holds WhatsApp beside SMS, RCS, email, voice, and video on one consent record and one bill — the channel fallback matrix maps the exact WhatsApp → RCS → SMS cascade, and the WhatsApp AI agents post shows an agent answering a WhatsApp chat and handing the same profile to voice. A single-channel vendor is a choice, and for some teams the right one; the price of it only comes due on the day the second channel enters the roadmap.
Sourcing note, per site standard
Every capability claim above was checked against the vendor's own published public scope — its website, pricing page, and public documentation — at the time of writing. BSP product surfaces in this segment move quickly; a vendor that ships SMS or email first-class after publication changes one ✗ in the table, not the archetype argument. Where a claim could not be confirmed from the public surface, the row says ◐ rather than asserting either direction. Vendors ship updates between edits; if a row no longer matches a vendor's published scope, the row needs the edit, not the reader's benefit of the doubt.
Where Orbit sits — with a disclaimer
Devotel Orbit is the comparison's sixth column and its publisher. The omnichannel scorecard, the consent-record argument, and the per-message pricing row argue the Orbit position by design, and a ranking published by one of the vendors is not a neutral benchmark. The side-by-side scorecards live on the /compare index, where each vendor page is labeled as our view. The site position stands as disclosed — read it and the carve-out above together.
Where WhatsApp-only still wins
Say it plainly, because it is true: an SMB whose entire customer communication is WhatsApp — an Indian D2C brand running broadcast campaigns and a support inbox on one WABA, no SMS or RCS roadmap, no voice program, no developers, and a finance team that prefers a flat INR plan — is served honestly by the WhatsApp-first shape. AiSensy's broadcast tooling, WATI's no-code bots, and Interakt's commerce surface are built for exactly that operator, and a team whose whole stack is one channel does not pay for the other five. The carve-out holds while three conditions hold: WhatsApp is the whole plan, subscription-plus-conversation pricing matches how the team wants to buy, and the consent record never has to gate a second channel. The moment an SMS fallback, an RCS lane, an AI voice agent on the same customer profile, or a contact-center queue enters the roadmap, the one-channel-consent problem stops being theoretical.

Frequently asked questions
Is WATI or AiSensy an API?
Both are products built on Meta's WhatsApp Business API rather than APIs themselves. Each publishes a developer surface behind its primary product — WATI behind the shared inbox and bot builder, AiSensy behind the broadcast console — so the GUI is the first user and the REST access is the secondary layer. A BSP that is API-first sells the endpoint as the product; none of the five in this segment does. Orbit's account exposes the WhatsApp channel through the same first-class API that carries SMS, RCS, email, and voice.
Can I run RCS plus voice from one of these BSPs?
Not from any of the five on their published scope — each is a WhatsApp-only product, so an RCS campaign, an SMS fallback, or a voice program means adding vendors outside the account. Orbit holds the channel set natively: the channel fallback matrix maps WhatsApp → RCS → SMS delivery, and voice joins the same consent record rather than a second vendor's list.
Which of them supports AI voice agents natively?
None of the five ships an AI voice agent; the chatbot builders across WATI, Gallabox, Interakt, AiSensy, and DoubleTick are flow bots scoped to WhatsApp conversations, not agents that answer calls or act across channels. Orbit's AI agents answer WhatsApp chats and the voice channel on the same customer profile — the WhatsApp AI agents post walks the handoff.
Which is cheapest for an Indian SMB on a low monthly volume?
Model the two shapes rather than ranking subscription sticker prices. The BSP pattern is a flat INR subscription tier plus Meta's per-conversation charges; Orbit's pattern is pay-as-you-go per message on the Pricing page with no platform subscription. At low or spiky volume, the per-message shape wins because a quiet month bills near zero; at high and stable volume, a flat subscription can amortize better. The WhatsApp pricing shift post shows the per-conversation mechanics both models sit on top of.
Do these BSPs handle consent and opt-outs the way Orbit does?
Each BSP keeps opt-outs inside its own WhatsApp account — a block in one channel's list. Orbit's suppression is tenant-owned state that gates every channel and exports with the contact, the discipline the SMS marketing playbook applies to ported consent. That difference matters the day a second channel opens, because a WhatsApp-only opt-out record cannot gate an SMS or voice send it cannot see.
