AgentCX Labs vs Stammer.ai vs Lety.ai: Honest 2026 Comparison
A side-by-side comparison of the leading white-label AI agent platforms in 2026 — Stammer.ai, Lety.ai, and AgentCX Labs — covering channels, providers, billing, and reseller economics.
Why this comparison matters in 2026
If you're an agency, BPO, or reseller evaluating white-label AI agent platforms in 2026, three names come up constantly: Stammer.ai, Lety.ai, and AgentCX Labs. They look similar at the surface — multi-tenant, branded dashboards, AI agents you can resell. But once you actually compare channels, voice providers, billing, and enterprise readiness, they diverge fast. This is the honest breakdown.
Stammer.ai: chatbot-first, voice as a bolt-on
Stammer.ai built its reputation as a white-label AI chatbot platform — text-based agents on websites, knowledge bases, and lead capture flows. Voice is available but it's not the core product. If your clients primarily need on-site chat widgets and you don't care about deep voice infrastructure or multi-provider flexibility, Stammer is a reasonable pick. The trade-off: you're locked into their underlying engine choices, voice is secondary, and there's no real multi-provider strategy for resellers who need to mix voice engines across clients.
Lety.ai: clean UI, single-provider, limited channels
Lety.ai is a newer entrant focused on white-label AI agents with a polished dashboard experience. It's well-designed and easy to get started — but the platform runs on a narrow provider stack and channels are limited. For agencies serving a single vertical with simple needs, it works. For BPOs and resellers with diverse client portfolios requiring voice + SMS + WhatsApp across multiple voice engines, the ceiling shows up quickly.
AgentCX Labs: multi-tenant, multi-provider, full omnichannel
AgentCX Labs is built for the reseller use case from day one. Multi-tenant client workspaces with isolated data and branding. Multi-provider voice — NLPearl, Retell, Vapi, and ElevenLabs all selectable per client. Voice + SMS + WhatsApp in one unified platform instead of voice-only or chat-only. Stripe billing already integrated so you can charge clients on subscription or per-minute markup without building a payments stack. Native hosting available for enterprise resellers who need data sovereignty and SOC2 / HIPAA-aligned workflows. It's the only one of the three designed specifically for BPOs and AI automation agencies that need to scale across many clients without re-platforming.
Side-by-side: what actually matters for resellers
Channels: Stammer is chat-first with voice bolt-on; Lety is voice-focused with limited channel mix; AgentCX Labs runs voice + SMS + WhatsApp natively. Voice providers: Stammer and Lety are largely single-engine; AgentCX Labs lets you assign NLPearl, Retell, Vapi, or ElevenLabs per client. Billing: Stammer and Lety leave most billing logic to you; AgentCX Labs ships with Stripe wired in. Hosting: Stammer and Lety are shared SaaS; AgentCX Labs offers native hosting for enterprise resellers. White-label depth: all three brand the dashboard, but only AgentCX Labs lets you fully control provider mix, billing, and hosting under your name.
Who should pick what
Pick Stammer.ai if you're selling website chatbots first and voice is a side offering. Pick Lety.ai if you want a single-provider voice platform with a clean UI and you're early-stage. Pick AgentCX Labs if you're a BPO, AI automation agency, or enterprise reseller that needs multi-tenant workspaces, multiple voice providers per client, full omnichannel (voice + SMS + WhatsApp), Stripe billing already integrated, and native hosting for regulated clients. AgentCX Labs is the only platform on this list architected for resellers who plan to scale across many clients and many use cases without re-platforming.
The honest bottom line
There is no single 'best' white-label AI agent platform — there's the best fit for your business model. But if you're reading a comparison post in 2026, you've probably already outgrown the single-provider, single-channel wrappers. AgentCX Labs exists for that moment: when you need a real reseller stack instead of a hobbyist white-label skin. Talk to our team if you want a live walkthrough against any platform on this list.
