Stammer
White-label AI agents for chat and voice, built for agencies to resell under their own brand.
Stammer is the most complete white-label reselling toolkit we've seen for AI agents. The zero-revenue-share model, branded client portal, and usage markup options make it a strong choice for agencies. However, solo businesses just needing a chatbot for their own site will overpay—look elsewhere.

Skip Stammer if you only need an internal chatbot for your own business without reselling features, or if you require advanced custom AI workflows beyond lead gen and scheduling.

About Stammer
Stammer is a white-label platform for building, deploying, and reselling AI agents that handle customer support, lead qualification, and appointment booking across chat and voice channels. Aimed at AI agencies, web development firms, and SaaS providers, it lets you launch conversational AI under your own domain and branding—clients never see Stammer, only your company. With 35K+ live AI agents and 12M+ conversations handled, the platform is battle-tested for scale. The no-code builder means you can deploy agents in days, not months, without a development team. Chat agents can be embedded on websites, Instagram DM, Facebook Messenger, WhatsApp, or connected via a rebrandable API. Voice agents handle inbound calls, outbound campaigns, lead follow-up, and appointment reminders with human-like natural conversation. AI scheduling syncs with Calendly, Google Calendar, and Cal.com, and a seamless human handoff keeps complex cases covered. For agencies, the economics are the headline: zero revenue share, you set your own client pricing, charge setup fees, and mark up usage. A branded client portal with real-time analytics—like calls handled and leads captured—makes renewals easier to justify, with agencies reporting charging $599/mo per client versus $299 without custom branding. Pricing starts at $197/mo for the Agency plan, $497/mo for Full SaaS Mode, and custom Enterprise tiers. You can also use your own OpenAI API keys for chat messaging to skip per-message fees. Compared to building your own agent infrastructure or using a non-white-label chatbot like Tidio, Stammer trades internal-use simplicity for a complete reselling toolkit built for agencies that want margin and branding control.
Behind the Verdict
Stammer's core strength is its white-label reselling model. For AI agencies, web dev firms, and SaaS providers, it offers a complete toolkit to brand, sell, and deliver AI agents as your own product. The zero-revenue-share model means you keep 100% of client fees, and you can charge setup fees, subscriptions, and usage markups. The branded client portal gives your clients real-time analytics on calls handled and leads captured, which helps justify renewals and upsells—one agency reported charging $599/mo per client versus $299 without custom branding. However, Stammer is not for everyone. If you're a solo business just needing an internal chatbot for your own website, the $197/mo minimum is steep compared to alternatives like Tidio or Chatbase. Additionally, the platform focuses primarily on lead gen, support, and scheduling; advanced custom AI workflows or marketing automation like email sequences are not built in. Knowledge base size caps (1M characters for chat, 5M for voice) may limit training on large catalogs, and concurrent call limits (3 on Agency, 5 on Full SaaS) could bottleneck high-volume voice operations. If you need deep niche CRM integrations or high-volume call centers, you may outgrow Stammer and should explore custom solutions or enterprise tools like Twilio or Retell. That said, for agencies that want to resell AI agents with full branding control and predictable recurring revenue, Stammer is a strong choice. Its pricing—$197/mo for Agency, $497/mo for Full SaaS, custom Enterprise—is reasonable compared to building your own infrastructure, and the ability to use your own OpenAI API keys for chat messaging lets you control costs. The platform is validated by over 1,300 agencies generating $300–500 MRR per client. If you fit the agency profile, Stammer is worth a serious look.

Where the pricing makes sense
The company stage and team size where Stammer's pricing actually pencils out — and where peers do it cheaper.
Stammer's $197/mo Agency plan is cost-effective for agencies reselling to multiple clients, with zero revenue share and markup potential. Compared to building your own infrastructure (e.g., Twilio + OpenAI) which can exceed $500/mo in engineering and hosting, or paying per-seat tools like Tidio that aren't white-label, Stammer offers a strong margin-driven pricing model for resellers.
Setup time & first value
How long it actually takes to get something useful out of Stammer — broken out by persona, not the marketing-page minute.
With the no-code builder, you can deploy your first agent in under an hour. For agencies, onboarding a client takes 1–2 days including training data, customization, and testing. Full SaaS Mode includes 1-on-1 onboarding for a faster start.
Switching to or from Stammer
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Tidio: Move from a non-white-label chatbot to Stammer by importing your knowledge base and rebuilding agents, then deploy under your own brand.
- →From vanilla chatbot builders like Chatbase: Use Stammer's API and white-label options to resell to clients, migrating your existing training data.
- →From custom-coded agents on Twilio + OpenAI: Replace with Stammer's no-code builder and white-label dashboard to save engineering time.
- ↗To Tidio or other simple chatbots: If you only need internal support, export your knowledge base and deploy a cheaper non-reselling chatbot.
- ↗To custom infrastructure (Twilio + OpenAI): For high-volume call centers with deep CRM needs, you may outgrow Stammer's caps and build your own.
