The short version

  • Only Retool has a free tier, so it costs nothing to try first.
  • Each has a real cost: Insider delivery depends heavily on the assigned account team, so results vary by region and a team change mid-contract can be felt immediately in campaign output.; Retool builders and internal users are billed as separate seat types, so the true cost depends on the mix rather than the headcount
  • They diverge on capability: Insider covers Architect journeys, Retool covers Drag-and-drop builder.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Insider

  • Delivery depends heavily on the assigned account team, so results vary by region and a team change mid-contract can be felt immediately in campaign output.
  • The suite is licensed by module, so the platform fee quoted at the start typically excludes the channels and predictive features that make the business case work.
  • Template-driven web personalisation targets the rendered DOM, which breaks on single-page applications that re-render after the template applies unless a developer wires in the framework hooks.
  • Reporting exports are limited compared with warehouse-native tools, so teams that want campaign data alongside finance data end up pulling it through the API on a schedule.
  • Contracts are annual and negotiated per traffic band, so a seasonal spike in visitors can push you into a renegotiation rather than a metered overage.

Retool

  • Builders and internal users are billed as separate seat types, so the true cost depends on the mix rather than the headcount
  • The free plan is capped at 5 users, 500 workflow runs a month and 5 GB of database capacity
  • Audit logging, permission controls, portals and custom branding all require the Business plan at $50 per builder per month billed annually
  • External user access is Business only, and is charged in bands above 50 users
  • Self hosted deployments mirror the cloud tiers but need Enterprise for unlimited users and SSO

Answered from the vendors’ own pages

Insider: Is WhatsApp actually usable at scale here?

Yes. It is a supported primary channel with catalogue and template message support, though WhatsApp conversation fees from Meta are passed through and are separate from the licence.

Retool: How much does Retool cost?

Retool offers a free tier. Paid cloud plans start at $10/month (Team - builders) or $5/month (Team - internal users), $50/month (Business - builders) or $15/month (Business - internal users). Enterprise pricing is custom. Annual billing provides 20% savings.

Insider: Can we run it without vendor help?

You can, but the pricing assumes a managed relationship. Teams with strong in-house campaign operations often find they are paying for services they do not use.

Retool: What is the difference between builders and internal users?

Builders are users who create applications in Retool, while internal users are those who only access and use the applications. Internal users cost significantly less than builders on all paid tiers.

Source
Insider: Does it work for B2B?

Rarely a good fit. The segmentation, recommendations and channel mix are built around high-frequency consumer behaviour.

Retool: Can I self-host Retool?

Yes, Free, Team, and Business tiers support self-hosting with comparable features to cloud versions. Enterprise is required for unlimited users, SSO, and advanced self-host features.

Source
Retool: What are AI credits and how do they work?

AI credits are used for app building and AI actions. Free tier includes 250 monthly credits, Team includes 1,000, and Business includes 3,000. Credits renew monthly without carryover and are pooled at the organization level.
