5 November 2026 · prices checked 4 and 5 November 2026 · by the HeyKiko team

The best Respond.io alternative depends on what you'd keep: SleekFlow for every messaging app at a lower price, Wati for WhatsApp-first marketing, HeyKiko for an AI agent on your website, WhatsApp and Telegram from the first plan, Trengo for support teams that also live in email, and Tidio, Botpress, Chatling or Chatbase for other needs. We make HeyKiko, so we've placed it where it fits rather than at the top, and every price links to the tool's own page.

## The 8 best Respond.io alternatives at a glance

This isn't a ranking: each tool is best for something different. We make HeyKiko, so we placed it where it fits.

| Tool | Best for | Starts at | Free option |
| --- | --- | --- | --- |
| 1. SleekFlow | Teams that want every messaging app for less | $49/mo, AI from $109 | 7-day Pro trial, no card |
| 2. Wati | WhatsApp-first marketing and support teams | Varies by country | 7-day trial |

| 8. Chatbase | Many channels and integrations in one AI agent | $40/mo | 7-day trial |

## What Respond.io does well

Respond.io is a strong product, and for some teams it's still the right choice. Its own pages list:

- Nearly every messaging app in one inbox: WhatsApp, Telegram, Instagram, Messenger, TikTok, Viber, LINE, WeChat, SMS and email
- AI agents that answer, route, book and transfer calls, from its Growth plan
- Calls on phone numbers, WhatsApp and Messenger, with AI voice agents on Advanced
- Mobile apps, HubSpot and Salesforce integrations, and ISO 27001

## Why people look for a Respond.io alternative

- Its $99 Starter plan has no AI agent: AI agents and knowledge start on Growth, at $199 a month
- Growth and Advanced charge for monthly active contacts above those included
- Broadcasts and booking also start on Growth
- Built for larger teams, which is more than a small business needs when one or two people reply

## What to look for in an alternative

1. **AI on the plan you'd buy**: Check which plan the AI agent starts on, and how it's billed: credits, conversations, or a charge per AI-handled chat.
2. **Contact and seat charges**: Some tools charge per monthly active contact or per seat. Price your real number of customers and teammates, not the entry plan.
3. **The channels you can't lose**: If you rely on LINE, WeChat, Viber or TikTok, fewer tools cover them. If it's WhatsApp, Telegram and your website, many do.
4. **WhatsApp fees**: Meta bills WhatsApp messages on every tool. Check whether the tool adds anything on top, and whether campaigns are included.
5. **What happens after the answer**: Booking, order lookups, cases and campaigns: built in, or through another tool you pay for.

| WhatsApp-first broadcasts and automations | Wati |
| An AI agent on website, WhatsApp and Telegram from the first plan | HeyKiko |

## How we chose

We included tools that train an AI agent on your own content and talk to your customers, and read each one's own pricing, product and docs pages on 4 and 5 November 2026. Prices are monthly billing before tax, in USD unless shown otherwise; Trengo lists euros, and Wati shows prices by country; each tool counts AI use differently (credits, messages or conversations), so compare at your own volume. We make HeyKiko, so we aren't neutral: we placed it where it fits and listed its limits too. If something here is out of date, [tell us](/contact).

## Respond.io alternatives: questions

### What is the best Respond.io alternative?

It depends on what you'd keep. SleekFlow covers almost the same messaging apps for less, Wati suits WhatsApp-first marketing, HeyKiko gives you an AI agent on your website, WhatsApp and Telegram from its first plan, and Trengo suits support teams that also work in email.

### Is there a cheaper alternative to Respond.io?

Yes, especially for AI. Respond.io's AI agents start on Growth at $199 a month. SleekFlow's AI agent starts on Pro at $109, Chatling at $25, and HeyKiko at $29 a month for 2,000 AI credits. Prices as of 5 November 2026.

### Which Respond.io alternative works on Telegram?

SleekFlow includes Telegram on every plan, HeyKiko on every plan, Chatling from its first paid plan, and Botpress through its integration; Tidio has it on Plus and Premium. We didn't find Telegram on Wati or Trengo.

### Which alternative is best for WhatsApp?

Wati is built around WhatsApp broadcasts and automations, SleekFlow and Trengo include WhatsApp in a wider inbox, and HeyKiko puts an AI agent on WhatsApp on every plan, with WhatsApp campaigns and AI that answers WhatsApp calls (Pro and up).

### Do these alternatives charge per contact?

SleekFlow charges for monthly active contacts above those included, like Respond.io's Growth and Advanced plans. Trengo charges per conversation, Wati per plan and user, and HeyKiko by AI credits and plan limits, not by contacts. Meta's WhatsApp fees apply on all of them.

### Which alternative supports LINE and WeChat?

SleekFlow, on every plan. Most of the others, including HeyKiko, don't offer LINE or WeChat; if those apps matter to you, SleekFlow or Respond.io itself is the better fit.

### How did you choose these tools?

We looked for tools that put an inbox or an AI agent on WhatsApp and other messaging apps, read each one's own pricing, product and docs pages on 4 and 5 November 2026, and wrote what each is best for. We make HeyKiko, so we placed it where it fits rather than first.
