The verdict
Custom domain on an AI tool is the single feature that turns a SaaS into a resaleable agency offering. The agency loads its own subdomain (chat.agencyname.com), strips out the vendor's branding, and resells the platform to clients who never know which tool powers it underneath. In 2026 most platforms gate custom domain behind Enterprise contracts ($1,000+ per month, annual). GoHighLevel and DM Champ are the two notable exceptions where custom domain ships in mid-tier plans ($297-$497 per month, no annual lockup). This list ranks the 10 tools that actually support custom domains and discloses what tier you need.
DM Champ is an AI sales agent platform with custom domain and white-label support that lets white-label resellers host the entire platform under their own subdomain with auto-SSL, custom logo, colours, app name, and SEO meta. The recommended way to get it is the AppSumo lifetime deal: one-time purchase, lifetime access, all future Pro-plan updates included, 60-day money-back guarantee. White-labeling is included from Tier 3 ($229) up, and the top tier ($999) adds unlimited sub-accounts plus credit reselling via Stripe, all permanent with no recurring platform fee. If you would rather subscribe than buy once, the same capabilities are available on the monthly Agency tier ($497 per month). If you want to see your own brand on the platform before you commit, the custom domain and white-label quickstart walks you through getting live in about an hour.

Where the market prices land
Line up the published monthly prices on this list and a clear pattern shows up: most white-label tools cluster between roughly $300 and $750 per month, with the enterprise-only names trailing off into four and five figures. DM Champ sits on the value tail because the recommended path is a one-time $229 AppSumo lifetime deal (white-label from Tier 3). The placement below is our editorial reading, not a precise count.
How we ranked these
We are DM Champ. We have a financial interest in this list. We placed DM Champ at #2 behind GoHighLevel because GoHighLevel is the broader agency platform standard with more brand recognition. DM Champ is at #2 because among the white-label-from-mid-tier tools, no other AI sales agent ships custom domain on a one-time AppSumo lifetime deal (white-label from Tier 3 at $229), let alone at $497 per month without an annual contract. Each tool was scored on the tier that unlocks custom domain, May 2026 published pricing for that tier, and whether the white-label is genuine (logo, domain, app name, colours) or just removed branding. Affiliate relationships: none.
1. GoHighLevel
Custom domain tier: Unlimited at $297 per month, full white-label SaaS at Agency Pro $497 per month. Best for: Marketing agencies running multi-client retainers with CRM, funnels, email, calendars, and SMS. Standout feature: Full white-label including iOS and Android apps (extra $50-$200 per month per app), SaaS mode with Stripe-billed sub-accounts, automated provisioning. Drawback: Sprawling product. Many agencies use only a fraction of the feature set. Phone, SMS, and AI usage are billed separately on top.
2. DM Champ
Custom domain tier: AppSumo lifetime deal, white-label from Tier 3 ($229 one-time). Also available on the monthly Agency tier ($497 per month) if you would rather subscribe than buy once. Channel: WhatsApp, Instagram, Facebook Messenger, SMS, Telegram, Email, web chat, custom channels via webhook. Best for: Agencies that specifically sell AI sales agents to consumer-facing businesses (dental, beauty, fitness, coaching). Standout feature: Custom domain with auto-SSL, custom logo, favicon, primary/accent colours, app name, SEO meta, Terms / Privacy URLs, support email. On the lifetime deal the top tier ($999 one-time) adds unlimited sub-accounts and credit reselling via Stripe at agency-set pricing, all permanent with no recurring platform fee. Plus webhook auto-recharge. Top up credits as needed or bring your own Anthropic key (BYOK). Drawback: Single category (AI sales agent for DMs). Does not include CRM, email automation, or funnels. Pair with another tool if you need those.
3. Tidio
Custom domain tier: Plus at $749 per month (per Tidio's published pricing, as of May 2026). Premium is custom-quoted ("contact for pricing") on Tidio's own page; third-party breakdowns put it around $2,999 per month. Best for: Ecommerce-focused agencies serving Shopify and WooCommerce clients. Standout feature: The Shopify integration is sharp. The white-label tier removes Tidio branding from chat widgets. Drawback: Plus tier at $749 per month makes the price-to-value ratio uncompetitive against DM Champ, which white-labels from a one-time $229 AppSumo tier (or $497 per month on Agency).
4. ManyChat
Custom domain tier: Enterprise / Partner programme, custom-quoted. Best for: Agencies already deep in the ManyChat partner ecosystem. Standout feature: Brand recognition. ManyChat is the default Instagram comment-to-DM tool, and partner pricing unlocks white labelling. Drawback: Enterprise pricing is opaque. ManyChat does not publish white-label or Enterprise pricing; it is custom-quoted, and agencies typically report quotes in the thousands per month for full white-label.
5. Botpress
Custom domain tier: Plus at $495 per month. Enterprise for full white-label. Best for: Technical agencies building custom chatbots with their own developer team. Standout feature: Open-source core. The Plus tier ($495 per month) supports white-label embedding. Strong for agencies that want to customise the bot logic deeply. Drawback: Steeper learning curve. AI Spend charges on top of the base price can compound unpredictably.
6. Voiceflow
Custom domain tier: Business at $150 per month for base white-label, Enterprise for full custom domain. Best for: Conversational AI agencies that need a visual flow builder with multi-channel deployment. Standout feature: The visual conversation designer. Strong for building branching dialog flows. Drawback: Three layers of cost (base subscription, per-editor seats, usage credits) make the total cost less predictable. A 5-editor team running 50K monthly support messages costs around $450-500 per month.
7. Ada
Custom domain tier: Enterprise only. Best for: Enterprise customer support orgs with 100K+ monthly conversations. Standout feature: Enterprise governance, security, and reliability. Built for Fortune 500 deployments. Drawback: Quote-based pricing. Typical contracts start at $30,000 per year. Not a fit for agencies under enterprise scale.
8. Drift (now Salesloft Drift)
Custom domain tier: Enterprise. Best for: Enterprise B2B SaaS that already runs Salesloft for sales engagement. Standout feature: Conversational marketing for B2B websites, deep Salesforce integration. Drawback: Abandoned public pricing after the Salesloft acquisition. Most quotes start at $1,000+ per month minimum for meaningful features.
9. Intercom
Custom domain tier: Expert tier at $139 per seat per month, plus Fin AI at $0.99 per resolution, plus add-ons. Best for: SaaS support orgs that want a polished customer support stack with AI on top. Standout feature: The Fin AI resolution-based pricing model is fair. Strong help center and ticketing. Drawback: Custom branding on Intercom is limited. The Intercom logo persists in many surfaces. True white-label requires enterprise contracts.
10. Userlike
Custom domain tier: AI Automation Hub starting around EUR 200 per month, plus EUR 40-80 per seat. Best for: German and EU-based agencies serving customer service teams. Standout feature: Strong GDPR compliance. Live chat widgets are fully customisable to brand. Drawback: AI features are an add-on, not core. Per-seat pricing on top of the base subscription stacks up.
11. Smatbot (bonus)
Custom domain tier: Higher-tier plans (above the $19 per month entry). Best for: Budget-conscious agencies in India, Middle East, and emerging markets. Standout feature: 50+ language support. Multichannel including WhatsApp, Instagram, Facebook, website. Drawback: Less feature depth than DM Champ or Botpress. UX feels dated.
When DM Champ is NOT the right fit
If your agency sells CRM, funnels, email automation, and SMS as part of a single bundle, GoHighLevel is the broader fit. DM Champ does AI sales agent only. If your clients need enterprise-grade support tooling (SOC 2 Type 2, SAML SSO, BAA agreements at the support layer), Intercom or Ada is the right answer. If you would rather not pay $497 per month for the Agency tier, the recommended path is the AppSumo lifetime deal (one-time payment, lifetime access, all future Pro-plan updates, 60-day money-back guarantee), with white-labeling from Tier 3 ($229) and unlimited sub-accounts plus credit reselling at the top tier ($999). If your agency is one-client-only, you do not need unlimited sub-accounts and a lower lifetime tier (or a cheaper monthly plan such as Growth $97 or Pro $297) is the better economics.
How to choose
Start with the customer count. If you serve 1-2 clients, custom domain is overkill, buy a lower lifetime tier or the Pro plan. If you serve 5-50 clients, custom domain plus sub-account reselling is the differentiator, that is the DM Champ AppSumo lifetime deal (white-label from Tier 3, unlimited sub-accounts and reselling at the top tier) or GoHighLevel Unlimited, with DM Champ Agency monthly as the subscription alternative. If you serve 50-500 clients with full SaaS billing, you need GoHighLevel Agency Pro, ManyChat Enterprise, or a custom-built platform on top of an API-first tool like Voiceflow. Match the tier to the actual book of business, not the dream.
