By Replaid · Reviewed · Based on linked product documentation
Replaid
A fit for developers and agencies with an existing agent, business knowledge, and a supported text-messaging workflow.
Beta access is by invitation. You configure and run the external agent.
respond.io
A fit for teams that need people and AI working in a shared inbox, with more channels and built-in automation.
Feature access, included usage, and extra charges depend on the plan.
MCP support is shared by both products. Compare the channel limits, review process, and tools needed for your actual conversations.
| What matters | Replaid | respond.io |
|---|---|---|
| External agents and MCP | Connect your chosen agent through MCP. Your agent supplies the knowledge, instructions, and reply text. | Connect external assistants through its hosted MCP server with OAuth. Tools cover contacts, messages, conversations, and AI agent settings. Source ↗ |
| Built-in AI and knowledge | An external agent is required. Keep business knowledge and reasoning in the agent or application you choose. | Configure built-in AI with knowledge from files and website URLs. Select which sources each agent uses. Source ↗ |
| Starting automation | Run your agent manually, on an external schedule, or through a webhook receiver. Connecting MCP alone does not start replies. | Build workflows with triggers and steps for messaging, assignment, and routing. Built-in automation runs within the platform. Source ↗ |
| Drafts and human replies | Save drafts and inspect them in Replaid. Enable sending when ready, then ask your agent to send a specific reply. There is no manual reply composer in the current app. | AI Assist suggests a reply in the inbox composer. A person can edit it before sending or write their own reply. Source ↗ |
| Action controls | Set action permissions and hourly limits, keep sending disabled while testing, check actions with dry runs, and inspect execution records. | Hosted MCP follows the connected user’s role. Built-in AI agents also have configurable conversation actions. Equivalent controls for every external-agent action were not verified. Source ↗ |
| Messaging channels | WhatsApp, Instagram, Messenger, Telegram, and a website widget. The current message workflow is text-based; WhatsApp replies require an open 24-hour customer-care window. | Includes WhatsApp, Instagram, Messenger, Telegram, web chat, email, SMS, LINE, Viber, and WeChat. TikTok Business Messaging is in beta; voice integrations are also listed. Source ↗ |
| Custom integrations | Use MCP, the REST API, and outgoing webhooks to connect your agent and other tools. Custom workflows run in your own integration. | Developer API access starts on Growth. Its integration catalogue also includes CRM and automation tools. Source ↗ |
| Platform and usage costs | A limited founding lifetime offer. Paid channel usage, external AI costs, and optional setup work are separate. | Recurring subscriptions, with contact allowances and included AI credits. Extra usage and channel fees can add to the bill. Source ↗ |
Replaid’s current limits: Each team can connect one Instagram account, one Facebook Page, one Telegram bot, and one Replaid widget. Telegram personal accounts and groups are not supported. Instagram, Messenger, Telegram, and the Replaid widget support text only; attachments are not supported on these four channels. TikTok is not available yet. Check channel requirements before connecting.
A lifetime offer and a subscription include different things. Compare the full workflow, including your agent, channels, contact volume, and setup.
The current offer is for the first 5 founding teams and includes $50 prepaid usage credit. There is no monthly platform fee under this offer. Paid channel usage, tax, external agent costs, and optional setup or maintenance are separate. Credit expires after one year. See the founding offer and terms.
Starter: $99/month, or $948/year.
Growth: $199/month, or $1,908/year.
Advanced: $349/month, or $3,348/year.
Prices are USD. Annual totals are billed yearly. Growth and Advanced start at 1,000 monthly active contacts. Extra contacts cost $12 and $15 per 100, respectively. WhatsApp fees are separate. Check current plans and limits.
respond.io includes AI credits for its built-in AI features. At the base contact tier, Growth includes 10,000 credits and Advanced includes 20,000. Agent replies typically use 2–5 credits; draft suggestions, translations, and chat summaries use 1 each.
On current paid plans, exceeding the allowance automatically adds $15 per 1,000 credits, rounded up. AI pauses at twice the included allowance. Read the AI credit rules.
Replaid does not include an AI agent. Your external provider charges for its own service. Replaid’s prepaid usage credit pays for supported paid channel operations; it is not a bundle of AI replies.
Use a real support question or lead enquiry with known requirements. Include a second message that needs a person’s decision.
Start with Replaid’s developer workflow or agency workflow. Keep your existing setup until the new workflow works with your channels.
Yes. It provides a hosted MCP server with OAuth for external assistants. Its setup guide does not clearly state a minimum plan, so confirm eligibility before buying. Read its hosted MCP guide.
No. Its limited founding offer has a lower initial platform price than a year of the listed respond.io plans. The products include different features. Your external agent, channel usage, and setup costs affect the total.
No. An MCP connection makes tools available when your agent runs. It does not start automatic replies. Your agent must be started by you, an external schedule, or a webhook receiver. Start with drafts and sending disabled, then test one permitted reply.
Consider respond.io if you need a manual reply composer, more channels, and visual routing workflows together. Consider Replaid if you already have an agent and want it to work with supported conversations under explicit action policies.
