| Tool | Best For | Free plan | Starting price | Main limitation | Reviewed |
|---|---|---|---|---|---|
| Pylon | B2B support teams serving customers in Slack and other channels, Teams that need account context during technical investigation | No public permanent free plan is advertised. Product access and agentic-support beta participation are sales-led. | Pylon does not publish a complete self-serve platform price table. Its help center lists legacy AI Assistants at an additional $50 per seat per month on Professional and higher tiers, phone support at $35 per seat monthly, and implementation packages at $1,000 or $5,000. Agentic Support is in beta and is expected to move to seat-plus-credit pricing at general availability. Obtain the exact base plan, minimums, channels, credits, migration, implementation, renewal, and overage terms in an order form. | Small teams needing transparent self-serve pricing | 2026-09-29 |
| Sierra | Large brands with enough repeatable service volume to measure outcomes, Teams that need one governed agent across chat, SMS, WhatsApp, email, and voice | No public permanent free plan is advertised; evaluation and deployment are sales-led. | Sierra does not publish a self-serve price list. It describes outcome-based pricing tied to agreed results such as a resolved request, saved cancellation, or sale, with blended pricing for work that cannot be cleanly attributed. Buyers should obtain unit prices, volume bands, implementation fees, minimums, outcome definitions, reversals, escalation treatment, audit rights, caps, renewal changes, and export terms in writing. | Small teams needing transparent self-serve pricing | 2026-09-26 |
| Cresta | Enterprise contact centers with substantial conversation volume, Teams unifying AI agents, human assistance, coaching, and quality intelligence | No public permanent free plan is documented. Buyers should request a scoped pilot with exit criteria, data-deletion terms, and production-equivalent integrations. | Cresta does not publish standard self-serve plan prices. Access is sales-led and likely depends on products, channels, seats, conversation volume, languages, integrations, implementation, support, retention, and regulated-data requirements. Require a quote that separates platform, model, telephony, professional-services, overage, storage, and renewal costs. | Small support teams needing transparent self-serve pricing | 2026-09-24 |
| Pylon | B2B support teams serving customers in shared Slack or Microsoft Teams channels, Post-sales teams that need support, account, product, call, and CRM context together | No public permanent free plan is documented; access is sales-led and some Agentic Support capabilities remain in beta cohorts. | Pylon does not publish a stable self-serve price for its core platform. Official help material lists optional implementation packages at $1,000 or $5,000, says data migration is volume-priced, and describes Agentic Support moving toward seat plus usage-credit pricing at general availability. Native phone and SMS is listed at $35 per seat monthly. Buyers need a written quote covering seats, channels, AI credits, migration, onboarding, retention, integrations, support, and renewal terms. | Small teams that need transparent self-serve pricing | 2026-09-24 |
| Synthflow | High-volume, repeatable call intents, Teams with staffed escalation | A permanent production-ready free tier should not be assumed; verify current trial, credit, and card requirements. | Voice-agent cost depends on plan, minutes, telephony, models, integrations, and concurrency. Verify current rates, included usage, overages, numbers, and contract terms on the official pricing page. | Per-minute economics can hide failed-call cost | 2026-09-30 |
| Aircall | Sales and support teams needing a shared phone system, Teams connecting calls to CRM records | Free access or a trial may be available; verify current limits before procurement. | $0/month | Very small teams needing one simple number | 2026-09-19 |
| Sendspark | AI sales outreach, Personalized video messaging | No ongoing free plan is highlighted on the official pricing page. Sendspark instead emphasizes paid plans and trial/demo flows. | $49/month | Priced above simple screen-recording tools like Loom-style products | 2026-07-09 |
| Intercom Fin | customer support workflows, Teams comparing AI options | Free plan or trial availability should be verified before purchase. | Free or trial access may be available. Paid plans vary by usage and team size. | Needs deeper hands-on testing before a final verdict | 2026-07-04 |
