Kapso vs Wabery (2026): Which One Fits an Agency Shipping Client Chatbots?

Short version with tables: Kapso alternative page. The published price ladder and agency verdict live there.

Most WhatsApp platform comparisons are lopsided. One side is a developer API, the other is a per-seat inbox with a drag-and-drop builder, and the honest answer is that they’re not competing for the same buyer.

Kapso is not that. Kapso is a developer-first, official WhatsApp platform with a sandbox, a CLI, an MCP server, serverless functions, and customer connection links. If you are technical and shopping, it’s a real option and it belongs on your shortlist.

So this comparison is narrow on purpose: two products that overlap almost completely on primitives, and differ on the thing that decides your bill.

Full disclosure: Wabery is us. Kapso’s free tier is better than ours and their entry plan includes twice the messages, and both of those are in here with the numbers attached. You were going to open their pricing page anyway.

What Kapso Does Well

Three of these are real, and one of them is the thing we’d fix about ourselves first.

A Genuinely Better Free Tier

2,000 messages a month against Wabery’s 500, plus a free pre-verified US number, plus unlimited agents and workflows. That is not a rounding difference. Wabery’s free tier gives you a shared sandbox number; Kapso’s gives you a real number of your own and 4x the volume.

If your evaluation involves pointing real traffic at a real number for a week before a card is involved, Kapso lets you go further. We’d rather say that than have you find out on their pricing page ten seconds after closing this tab.

Twice the Messages on the Entry Paid Tier

Kapso Pro is $25 for 100K messages. Wabery Pro is $15 for 50K. Kapso costs $10 more and includes twice the volume.

Worth knowing where that stops mattering: the marginal rate is nearly identical. Wabery’s extra capacity is $15 per 50K, which is $0.30 per 1,000. Kapso’s Platform tier is $299 for 1M, which is $0.299 per 1,000. Neither of us is meaningfully cheaper per message. The difference is what’s bundled at the entry price, not the rate.

Centralized Meta Billing

On Platform, Kapso will consolidate Meta’s messaging charges for all your customers into one place. Wabery does not do this: your client pays Meta directly at Meta’s published rates.

If your agency wants to bundle messaging into one invoice, or mark it up, that’s a real capability we don’t have. We think client-pays-Meta is cleaner and easier to defend in a pricing conversation, but “cleaner” is our opinion and “one invoice” is a legitimate business preference.

Simple Economics if You Have Few Numbers

Three numbers for $25 is easy to reason about. If you’re a product team adding WhatsApp to one product rather than an agency with a growing client list, the per-number model is simple and fine, and the client-count argument below does not apply to you at all.

Where Wabery Is Different

You Are Billed Per Client, Not Per Number

This is the whole comparison in one line.

Kapso’s unit is a connected phone number. Wabery’s unit is a Live client project: contacts, conversations, channels, credentials, and environments isolated per client, and a bill that tracks how many clients you actually have live.

At one or two clients, Kapso is the better deal. Then the curves cross and keep separating. Published rates, both sides at their cheapest configuration:

Wabery’s math: $15 base includes two Live projects, the next eight are $5 each, everything after that is $3. Kapso’s math: $25 includes three numbers, additional numbers are $10 each until Platform’s $299 for 50 becomes cheaper at around 31 numbers, then $5 each above that.

Two caveats so this table isn’t doing anything sneaky.

Message allowances differ. The Wabery column assumes you’re inside 50K shared messages a month, and the Kapso column assumes 100K on Pro or 1M on Platform. Ten clients sharing 50K is 5K each, which is fine for booking and lead capture and not fine for high-volume support. Add capacity and the gap narrows: at 10 clients and 500K messages a month, Wabery is about $190 against Kapso’s $299. At roughly 900K messages, Kapso’s Platform bundle wins outright regardless of client count.

So the honest summary is a shape, not a winner. Wabery gets cheaper as you add clients. Kapso gets cheaper as you add messages. Find the corner you’re in.

A Client Project Uses No Live Capacity Until It Goes Live

A project flips to Live automatically the first time a real client channel connects. Until then it uses no paid Live-project capacity, with an unlimited number of draft and sandbox projects on Pro. Shared-sandbox delivery is separate: it is free through September 30, 2026, then draws from wallet credit at Meta’s published destination-market service rate without markup.

For an agency, that maps directly onto the sales cycle. Build the demo, pitch it, and pay only when the deal closed and the number connected. You are not carrying platform cost for pipeline.

Draft and Live Are Separated by a Publish Gate

A hosted agent has a Draft version and a Live version. External tools, including an MCP-connected coding agent, cannot publish Live. You edit Draft, test on the sandbox, then Review and publish yourself.

When you’re running other people’s customer-facing numbers, an approval step between “the agent rewrote it” and “the client’s customers see it” is not bureaucracy. It’s the reason you sleep.

More Than WhatsApp in the Same Project

WhatsApp is the primary channel, and a project can also include Instagram and Messenger with no per-connection fee. When a client asks for Instagram DMs six months in, it’s a channel on the existing project, not a second platform decision.

Describe It and Get a Working Draft

Both products expect you to build. Wabery adds a path where you describe the client’s job in plain language and get a working chatbot to test in the sandbox, which you then refine in the automations canvas or in code. It matters less for you than for the non-technical half of your agency, who can now edit a client’s keyword menu without opening a PR.

Where They’re Genuinely the Same

Do not pick on these, because they’ll be a wash:

• Official WhatsApp. Both are on the official Business API. Neither is doing QR pairing or unofficial libraries.
• Sandbox first. Both let you build and test before any Meta setup exists.
• CLI and MCP. Both are scriptable from a terminal and buildable from an AI coding agent.
• Functions. Both run your code on their infrastructure so you don’t operate a worker fleet.
• Flows and handoff. Both do native in-chat forms and a way for a human to take the thread.
• Meta fees are separate. Neither marks up messages. Meta charges its published rates either way.

If your shortlist is these two, the primitives are not going to decide it.

How to Choose

Pick Kapso if: you’re a product team adding WhatsApp to one product, you want the larger free tier to evaluate with, your message volume is high and your number count is low (roughly, past 900K messages a month), or you specifically want to consolidate and mark up your customers’ Meta billing.

Pick Wabery if: you’re an agency whose client count grows faster than your message count, you want each client’s data and credentials isolated by default, you want unpaid projects while deals are still in the pipeline, you want a publish gate between an AI agent and a client’s live number, or you’ll eventually need Instagram and Messenger on the same project.

Try both if: you’re between the two descriptions. Both have a free tier and a sandbox, both take about an afternoon to get a message flowing, and neither has a contact-sales gate in front of the thing you’re trying to test. That is a rare and good state of affairs, and it means you can settle this empirically instead of by table.

The Short Version

Kapso and Wabery agree on almost everything that matters technically: official WhatsApp, sandbox first, CLI, MCP, functions, Flows, no message markup. That agreement is a good sign for anyone building on WhatsApp in 2026.

They disagree on what they count. Kapso counts numbers and messages. Wabery counts clients.

So the decision is arithmetic, not taste. Kapso is cheaper at one or two clients and at very high volume. Wabery is cheaper everywhere in between, which is most of an agency’s life: $55 against $95 at ten clients, $85 against $195 at twenty.

Write down how many clients you expect live in a year and how many messages each one really sends. Then price both. That’s the answer.

Condensed side-by-side, plus the sandbox-to-client-number path: Kapso alternative for agencies.
