All the channels your customers use - with a free plan and self-hosting

Plain is an API-first B2B support tool with strong developer ergonomics, but it has no free plan and lacks consumer channels. Replynivo gives you 12+ messaging channels, an AI agent and copilot billed in credits, and transparent pricing with the option to self-host.

  • WhatsApp, Instagram, Telegram, TikTok, and more - channels Plain does not support
  • Captain AI agent and copilot on every paid plan, billed in credits
  • Free plan with 2 agents on live chat - no 7-day trial deadline
  • Self-host for complete data control
  • Open source with full code access - not just API-first

Why teams switch from Plain

Common pain points that lead teams to explore alternatives.

  • No free plan after the trial

    Plain offers a 7-day free trial, then per-user paid plans. Replynivo has a free plan for 2 agents on live chat, so a small team can keep using it with no deadline.

  • No consumer messaging channels

    Plain supports Slack, Teams, Discord, and email but has no WhatsApp, Instagram, Facebook, Telegram, TikTok, or LINE integration. Consumer-facing teams need a separate solution.

  • Closed source, cloud-only

    Plain is not open source and offers no self-hosting. Your customer data lives entirely on their infrastructure with no alternative.

  • Newer platform with limited track record

    Plain is a smaller, newer company. Replynivo has 37k+ GitHub stars, thousands of self-hosted deployments, and years of production usage across industries.

What makes Replynivo the right choice over Plain.

  • AI billed in credits

    Captain AI agent and copilot is available on paid plans, billed in credits and not per resolution.

  • Free plan with no trial expiry

    Two agents on live chat at no cost, forever. Plain offers a shorter free trial.

  • Proven at scale

    Thousands of businesses run Replynivo in production. Battle-tested with years of community development and enterprise deployments.
