9 Best Chatbot Builders for Agencies of 2026

Stammer.ai is built around the agency business model rather than a single company's support desk. The Pro plan at $99 a month removes all Stammer.ai branding, runs on your own domain with your logo and colors, and includes 5 chat agents and 5 voice agents, with more at $10 a month each. Billing is the part agencies will notice: you keep a prepaid Agency Wallet, each client gets a Sub-Account Wallet, and you set the price clients pay per reply or call minute. The pricing page gives the example of buying a GPT-4o reply for $0.01 and reselling it for $0.05. Pro also adds MCP support, your own LLM API keys, a white label API and a 1-on-1 onboarding call. The $49 Standard plan is a test bed with 500 replies and 120 voice minutes but no white labeling. Usage is charged per model from the wallet, so margins depend on the model you pick.

GoHighLevel is the default stack for many marketing agencies, and its chatbot is one part of a larger client package. Conversation AI answers questions, qualifies leads, books appointments and hands off to a person across SMS, WhatsApp, Facebook Messenger and Instagram Direct Messages, inside the same CRM that runs pipelines, funnels, email and reviews. Agency Starter at $97 a month covers 3 sub-accounts, which suits a new agency testing the model. Unlimited at $297 a month removes the sub-account cap and adds the white-label desktop app, basic API access and pass-through billing, and Founder at $497 a month adds SaaS mode, where clients sign up for your own branded subscription. The AI pieces cost extra: AI Employee plans run $20, $50 or $97 a month per sub-account, and usage charges apply to Conversation AI and Voice AI. Agencies that only want a website bot will pay for a lot of unused software.

Botpress suits agencies whose clients need more than a docs bot: multi-step logic, tables, actions in other systems and handoff into Intercom, Zendesk, HubSpot or Salesforce. The free plan includes 3 AI agents and 100 conversations, enough to build a proof of concept for a prospect. Plus costs $150 a month billed annually and adds unlimited agents, white-label webchat, a Help Center on a custom domain and $25 of AI usage, with each conversation covering $0.10 of model cost. Extra volume comes in packs of 100 conversations for $65, added automatically when you near the quota. For agencies the business side is a referral model rather than a resale console: Affiliates earn 30% commission on users they onboard, and those who deliver projects can move up to Partner. There is no client sub-account billing like Stammer.ai, so most agencies bill clients separately and run each bot in a workspace.

Voiceflow has split its pricing page in two, and the agency half is aimed at exactly this audience. The For Agencies and Partners plan starts with a free trial and no credit card, then bills by usage with optional auto top-ups. It includes multi-client workspace management, white-labeling and client handoff tools, and access to all major model providers. The builder is aimed at production work: agents combine playbooks with deterministic workflows, connect to client systems through functions, API tools and MCP servers, and can be tested with simulations and LLM-powered evaluations before release. Deployment covers chat, voice, SMS and API, with environments for development, staging and production. Voiceflow lists SOC 2 Type II, ISO 27001, GDPR and HIPAA, which helps when a client's security team reviews the vendor. The pricing page does not publish usage rates, so agencies need to model costs inside the trial.

YourGPT is a credit-based chatbot builder that works well for agencies running a handful of client bots. Essential costs $39 a month billed annually, or $59 monthly, with 2 chatbots, 200 webpages, 20 documents and 3 team members, and every plan includes unlimited integrations. Professional at $79 billed annually raises that to 5 chatbots and adds the Chatbot Studio, API and webhooks, lead generation, multi-language support and handoff to a human. The agency features sit on Advanced at $349 a month billed annually: removal of the Powered by YourGPT mark, custom branding, a custom domain, custom roles and 10 chatbots with 100 million AI credits. YourGPT lists web chat, WhatsApp, Instagram, Telegram, Slack and other channels. It does not publish a reseller console with client wallets, so agencies set their own retainer and pay YourGPT directly.

ChatBotBuilder.ai pitches its Pro plan at serving both your own business and your clients, which makes it a practical start for agencies that sell Messenger, Instagram and WhatsApp bots. For $49 a month you get unlimited user seats, channels across Facebook, Instagram, WhatsApp, Telegram, SMS, email and voice, built-in marketing tools and an included OpenAI key with 5,000,000 tokens. The vendor states it is certified by Meta. The jump to white label is steep: White Label Enterprise costs $2,499 a month and adds unlimited accounts and admins, 1M contacts, your own brand and domain, complete SaaS mode and a 24/7 dedicated support agent. At that tier you must connect your own API key, and white label and custom domain sales are final with no refund. Integration counts are not published on the pricing page.

Typebot is a flow builder for chat forms and chatbots, and its license is written with freelancers in mind. The self-hosting docs state that a freelancer can create bots for clients on a self-hosted instance, while selling access to the instance itself or hosting Typebot for others is not allowed. On Typebot Cloud, the free plan has unlimited typebots and 200 chats a month, Starter at $39 a month removes Typebot branding and adds 2 seats and 2,000 chats, and Pro at $89 a month adds custom domains, WhatsApp and 5 seats with 10,000 chats. Every plan allows webhooks and custom JavaScript and CSS, with Zapier, Make.com and Pabbly Connect integrations. That makes it a good fit for lead capture, quote forms and guided support flows. It is not a reseller platform: there are no client wallets or sub-accounts, and the agency bills clients itself.

DocsBot is a documentation and support chatbot first, and agencies reach it through the Business plan. At $499 a month, Business includes 10 bots, 100k source pages, 60k AI credits and 10 team users, plus unbranded chat widgets and per-bot roles that the pricing page describes as being for reselling or multiple departments and workspaces. That lets an agency give each client access to its own bot only. Below that, Personal at $49 a month covers 1 bot with 5k source pages, and Standard at $149 covers 3 bots, escalation tickets and native CRM lead delivery, but both keep DocsBot branding. Reporting is a strength for client renewals, with topic reports, sentiment analysis and AI question reports on Business. The free plan with 50 source pages and 100 AI credits is useful for a pitch. There is no built-in usage rebilling, so the agency charges clients on its own invoices.

CustomGPT.ai fits agencies whose clients care most about accurate answers from their own documents, such as associations, consultancies and professional firms. Standard costs $89 a month billed annually, or $99 monthly, and includes 10 agents, 5,000 documents per agent knowledge base and 1,000 queries a month, so a small agency can host several client agents in one plan. The agency feature is on Premium at $449 a month billed annually: removal of the Powered by CustomGPT.ai branding and white-labeling, with 25 agents, 20,000 documents per knowledge base and 5,000 queries. The vendor lists 92+ languages, a RAG API and data connectors for sources like Google Drive, Notion and HubSpot. It also runs a solutions partner program and an affiliate program. The cost per white label seat is high next to Stammer.ai, and query caps need watching when several clients share one plan.
