What are the best alternatives to Darwin AI?

The first reason is that there is no price to compare. Its pricing page returns a 404 error, verified on 14 August 2026, and its site publishes no entry plan, billing unit, included allowance or overage cost. Everything goes through a call. That does not make it expensive or cheap: it makes it incomparable, and it forces the first conversation to be a sales discovery call instead of a decision you could make on your own, at your desk, on a Sunday.

The second is that there is no billing documentation either. Its help center has no billing section, so we found nothing published about which currency it charges in, whether it requires a minimum term, how much notice cancellation takes, or what happens when you exceed the contracted volume. When none of that is published, your contract is the only source of truth, and whatever you did not ask for in writing before signing does not exist afterwards.

The third is how far the human team reaches. Darwin describes AI employees that do the work, but it does not document a shared team inbox or a multi-user CRM as a core product — somewhere your people step in, read the history, take the conversation and hand it back. That is an absence of public documentation, not proof that it does not exist, which makes it exactly the thing to ask for in a demo before signing: how many people get in, what they see, and what they can do.

The fourth is channels. Its site talks about WhatsApp, Instagram and calls. We found no Messenger, email or chat on your own website. If your operation already receives conversations and comments in more places than those three, the channel count starts deciding the purchase before the quality of the agent does.

The fifth is the invoice for a Mexican buyer. The company is based in Buenos Aires and publishes no peso price, Mexican entity, VAT treatment or CFDI commitment. That row is shared by almost everyone on this list, but when there is no published price either, the buyer ends up negotiating two things blind at the same time: what it costs and how it gets invoiced.

• It publishes a price. That is the criterion ordering this list, because it is exactly what is missing on the other side.
• It publishes its billing unit and what happens when the allowance runs out — the monthly figure alone is not enough.
• It does the same job: selling and answering over messaging with AI agents that execute, not only draft.
• It can be bought from Mexico today, even when it bills in dollars; where no Mexican entity or local invoicing is published, this page says so.
• Every claim here links to the vendor's public page and carries its verification date.

Eva is our product and appears on this list, so the list is not neutral by nature; that is why every row links the public page it came from. Darwin AI publishes no price: its pricing page returned an error on 14 August 2026, so this page prints no Darwin figure — neither its own nor a third-party estimate — and everything it says about the product comes from Darwin's public site, getdarwin.ai, read the same day. The respond.io and Wizybot prices were verified on 14 August 2026; the Aurora Inbox and Kommo prices on 28 July 2026. Every figure is printed in the currency its vendor publishes, without conversion.

1. 1. Eva

   Best for: Anyone who needs Eva's five foundations: Eva does the work, not just the talking: She quotes from your real catalog, books, takes payment, invoices and follows up for months — inside the same conversation. A built-in CRM where everything organizes itself: Every prospect is captured, classified and managed automatically, and Eva works with your team: handoff to a person with the full history. Every channel included: WhatsApp, Instagram, Messenger, calls, email and your website — including Instagram comments and TikTok ad comments. AI is already in the price: No separate accounts and no extra AI charges: each agent reply uses one plan credit, and that is it. Public pricing: Plans, add-ons and setup published, with a verification date on every figure on this page. From $191 USD per month on an annual plan ($229 USD month to month).

   Tradeoff: From $191 USD per month on an annual plan ($229 USD month to month) on Essential, with 5,000 credits and 5 users included; a 1,000-credit top-up costs $49 USD and each extra user is $17 USD per month. Setup is purchased separately from $579 USD (half price with an annual plan) and payment inside the conversation runs on SPEI. Eva is one agent configured for your business, not a catalog of packaged employees by job title: if what you want to buy is a ready-made collections agent with a name, that row belongs to Darwin. There is also no public self-serve signup or free trial today.

2. 2. respond.io

   Best for: A mid-size or large team that wants the reference multi-agent inbox with everything published: prices, included users, AI credits, workflows, reporting and API, plus a seven-day trial with no card. It is the closest thing on this list to Darwin's multichannel ambition, with the difference that you can read the rate card before talking to anyone.

   Tradeoff: From $79 USD per month billed yearly on Starter, but the autonomous agent does not live there: AI Agents start on Growth at $159 USD per month, and Advanced costs $279 USD per month. There are four meters running at once — subscription, users, monthly active contacts and AI credits — and Meta's WhatsApp fees sit outside, on a balance you top up yourself. An extra block of 1,000 AI credits costs $15 USD, and there is a hard cap: at twice the included allowance the AI switches off until the next cycle. It bills in dollars only and publishes no Mexican entity or CFDI.

3. 3. Aurora Inbox

   Best for: Anyone leaving Darwin because they need a Mexican invoice and a number their accountant can budget. Aurora publishes a monthly peso price with three users included on every plan, an AI agent with 800 monthly responses from the entry plan, the three Meta channels, and invoicing with Mexican tax identifiers and downloadable CFDI files.

   Tradeoff: $1,800 MXN per month plus VAT for Aurora CRM, and $240 MXN per month plus VAT for each additional user or channel. It publishes no AI-response overage price, so that row has to be asked about. And it has nothing equivalent to Darwin's employees by job title or its phone calls: it is an inbox with an agent, not a catalog of profiles trained per vertical.

4. 4. Kommo

   Best for: Anyone who discovers, while talking to Darwin, that what they actually lack is a sales CRM: visual pipeline, tasks, contact records and campaign analytics, with messaging inside and several WhatsApp numbers.

   Tradeoff: $15 USD per paid user per month on Básico, with no monthly option: the published minimum is six months prepaid, meaning $90 USD per seat before you start. The autonomous agent is not available to new Básico customers — it starts on Avanzado at $25 USD per paid user per month — and the price multiplies by every person who needs access. It bills in dollars only and says an official partner may resell in local currency, but publishes no such price for Mexico.

5. 5. Wizybot

   Best for: A Shopify store that wants the agent answering this week: a single public plan, unlimited human agents, WhatsApp campaigns with no published cap, and WhatsApp, Instagram, Facebook and email channels, with unlimited AI messages in the first month and no implementation fee.

   Tradeoff: $69.99 USD every 30 days, with 1,250 AI messages and 2,500 AI comments per month; after that each extra message costs $0.07 USD and each comment $0.05 USD, and that meter empties fast in a store with traffic. Its Custom plan publishes no price. It is built around e-commerce rather than long commercial follow-up: we found no stage-based CRM and no collections, which is exactly what Darwin packages as Lucas.

Eva is our product and comes first, so here are the criteria: published pricing, published billing unit and overage, the same commercial job over messaging, availability to buy from Mexico, and every claim with a source and a date. Eva comes first because it combines an agent that executes, an included CRM, every channel, AI inside the price and a public rate card. respond.io follows for large teams that want the mature inbox and can read four meters at once; Aurora for buyers who need pesos and CFDI; Kommo for anyone who actually wants a per-seat sales CRM; and Wizybot for Shopify stores. Darwin AI keeps a real advantage: prebuilt employees by job title, trained for Latin American verticals, with phone calls and human guidance in Spanish. If that is the purchase you want to make and quoting by call does not bother you, stay where you are.

The first step is the WhatsApp number. Darwin is a Meta Business Partner working on the official API, so your number already lives inside Meta: changing vendors means migrating the WhatsApp Business account between platforms, with verification in the middle. Plan for days rather than minutes, and ask for the release procedure in writing before you sign with the next vendor.

The second is everything that is not published, and with Darwin that is nearly all the commercial terms. Before signing or renewing, ask for four things in an email: price and currency, what gets counted and what the overage costs, minimum term, and cancellation notice. When there is no pricing page and no billing section, that email is your only defense — and it is worth having even if you stay.

The third is your data. We found no public documentation for exporting conversations or contacts, so treat it as the risk it is: ask for the export clause in the document you are going to sign, and for a test export before you cancel anything. An already-cancelled account is the worst possible moment to discover a missing field.

The fourth is the configuration. Darwin's employees arrive prebuilt and tuned alongside their team, and that work does not copy across to the next vendor: it gets done again. With Eva, guided setup is prepared from your website and catalog and you approve it at no cost, while assisted setup costs $579 USD once, delivered within five business days of receiving complete inputs. With respond.io, Aurora, Kommo and Wizybot the configuration is yours to build beyond whatever the plan includes.

The fifth is the overlap. Budget one month paying both vendors: nobody switches off a sales channel to test another one. Run the replacement on a secondary channel or a bounded time window, compare real resolved conversations rather than demos, and move when the number convinces you.

And on our side, so you know what is left for you: we handle the number's migration inside Meta ourselves, the same way we handle your company's verification. Your contacts come into Eva by CSV or Excel file, with deduplication on import; your catalog comes in by file or by API; and on top of that a contact is created and updated on its own the moment the person writes. Ask your current vendor for the export and we go through it with you during setup, before you cancel anything.
