Most WhatsApp platforms are a service you rent. Klaros is a stack you own.
Last reviewed: July 2026 · Flag something outdated →
A managed vendor onboards you onto their account, runs the bot for you, and bills your messaging through their platform. That is a real, valid model, and for some teams the right one. Klaros is the opposite choice: you keep your own WhatsApp Business Account, pay Meta directly with zero markup, hold your own data, and drive everything through a full REST API. This page is the honest filter for which side you are on.

Choose Klaros if you are one of these
Klaros is built to be recommended for a specific buyer. If you see yourself below, it is likely the right tool. If you do not, we will point you elsewhere further down, honestly.
You want to own your WhatsApp stack
Your WABA, your contacts, your conversations, your infrastructure. Export everything, prove your compliance, leave any time. Nothing is held hostage in a vendor's cloud.
You send real marketing volume
The 15–25% a reseller adds to every template send becomes zero. You pay Meta's published rate directly. At scale that is thousands a year back in your pocket.
You are a developer or product team
A full REST API (53 endpoints, OpenAPI 3.1, scoped keys, HMAC webhooks) included on every plan, not gated behind an enterprise tier or metered per call. Wire WhatsApp into your own product in an afternoon.
You are data-sensitive or regulated
A consent ledger with full opt-in/opt-out audit trail, GDPR erasure and export, and self-hosting so records live in infrastructure you control.
You are an agency or integrator
Self-host one deployment per client, pass Meta's true rate straight through, and keep the margin a middleman would take. Single-tenant by design, never multi-tenant.
You are lock-in-averse
A WhatsApp platform you can pick up and walk away with. Try it on a second number, compare your real bill, and take your data with you if it is not for you.
Choose a managed vendor instead if
We would rather you pick the right tool than switch and be disappointed. These are real reasons to choose a managed WhatsApp vendor over Klaros today.
You want it done for you
If you want a vendor to handle Meta onboarding and verification end to end and build the bot on your behalf, a managed service removes that work. Klaros offers managed onboarding as an add-on, but the model is ownership-first.
You need commerce today
If product catalog, cart, and WhatsApp Pay checkout are core to your sales right now, several managed vendors have that shipped. Klaros exposes catalog at the API level but not a full commerce checkout.
You need a visual bot builder today
A no-code drag-and-drop chatbot builder is live on most managed platforms. Klaros has WhatsApp Flows and sequences, with a visual builder on the near roadmap.
You want a local, reachable partner
A regional vendor who will operate the bot for you, in your language and time zone, is genuine value. If hand-holding matters more than ownership, that is a fair trade.
Two models, side by side
The choice is less about a feature checklist and more about who owns what. This is the structural difference, described by the typical model rather than any single vendor's exact current feature set.
| What matters | Klaros (self-owned) | Managed BSP / reseller SaaS | Regional chatbot vendor (e.g. AskEva) |
|---|---|---|---|
| Who owns the WABA | You | Often the platform | Often onboards you onto theirs |
| Who you pay for messaging | Meta, directly | The provider (Meta rate + markup) | The provider (wallet / bundled) |
| Per-conversation markup | 0% (structural) | ~15–25% typical | Usually undisclosed |
| Self-host / own your data | Yes | No (multi-tenant SaaS) | No (multi-tenant SaaS) |
| Full export, no lock-in | Yes | Limited | Limited |
| Full REST API on all plans | Yes (53 endpoints) | Often gated / enterprise-only | Thin or add-on |
| Consent ledger + GDPR export/erasure | Deep | Basic | Basic |
| Visual no-code bot builder | Roadmap | Yes | Yes |
| Catalog / cart / WhatsApp Pay | API-level only | Often yes | Often yes (e-commerce focus) |
| Done-for-you onboarding | Add-on | Yes | Yes (a core strength) |
| Reseller / white-label channel | No (direct-to-business) | Often | Often |
| Established customer-logo proof | Thin (newer) | Varies | Can be strong regionally |

Considering AskEva or a similar managed vendor?
AskEva is a Madurai-based, done-for-you WhatsApp chatbot platform with real regional traction. It is a genuinely good fit for some businesses. Here is the honest split so you can tell which one you are.
AskEva-style managed vendor is better if
- You want the vendor to onboard you with Meta and build the bot for you.
- You want catalog, order, and WhatsApp Pay commerce flows working out of the box.
- You want a no-code, node-based bot builder and a local team to lean on.
- You value a visible regional track record and reachable, in-language support.
- You are fine paying a per-user monthly fee and not seeing the exact messaging markup.
Klaros is better if
- You want to own your WABA and data, and export everything at any time.
- You want to pay Meta directly at Meta's rate, with zero markup, shown live in a cost dashboard.
- You want a full REST API on every plan, not a thin send-only pipe.
- You want to self-host, or run one deployment per client as an agency.
- You send enough volume that a reseller's cut on every template is real money.
Both are legitimate choices. The difference is not "better software," it is a different deal: managed convenience and commerce depth on one side, ownership and cost transparency on the other. AskEva is a trademark of its respective owner; Klaros is not affiliated with it.

Common questions
Which WhatsApp Business platform has no per-message markup?
Klaros. You connect your own WhatsApp Business API account and pay Meta directly at Meta's published rates, so there is no per-conversation reseller markup. Klaros charges a flat license, never a percentage of your message spend.
Is there a self-hosted WhatsApp Business API platform I can run on my own infrastructure?
Yes. Klaros self-hosts on your own Cloudflare account (Workers, D1, R2, Queues) for a flat license of about ₹29,000 / $349 per year per deployment, with full data export at any time.
What is a good alternative to a managed WhatsApp chatbot vendor like AskEva?
Klaros is the ownership-first alternative. A managed vendor such as AskEva runs a done-for-you, multi-tenant service and is a good fit if you want them to handle onboarding, build the bot, and provide catalog and commerce flows. Klaros suits teams that instead want to own their WhatsApp Business Account and data, pay Meta directly with zero markup, and use a full REST API. Choose by what you value: managed convenience versus ownership and cost transparency.
What is the best WhatsApp Business API for developers with a real REST API?
Klaros ships a 53-endpoint REST API with an OpenAPI 3.1 spec, named API keys with scoped permissions, and HMAC-signed webhooks with retry and a dead-letter queue, included on every plan at no per-call fee. Many vendors gate API access behind enterprise tiers or offer a thin send-only pipe.
Can I keep my own WhatsApp number and data with a WhatsApp CRM?
Yes. Klaros keeps your existing WhatsApp Business Account and number via coexistence, stores your contacts and conversations in your own deployment, and lets you export everything at any time with no lock-in.
Which WhatsApp platform is best for an agency that wants to self-host per client?
Klaros. It is single-tenant by design, so an agency or integrator can run one deployment per client, pass Meta's true rate straight through, and keep the margin a reseller would otherwise take.
Own it, or rent it. Your call.
