The Front alternative for AI agents that answer on chat apps

Front is a polished help desk for teams that live in email, and it now lets you bring your own AI agent into it. But it is still a place for a team to work tickets, priced per seat — and it does not list LinkedIn. If what you are building is an AI agent that answers customers directly on the WhatsApp, Instagram, LinkedIn and Messenger accounts a business already has, you need the connection, not the help desk. That is what Spaces is.

Every Front fact below comes from Front's own website, help centre and developer docs, checked on 11 November 2026. Where Front is the better choice, we say so.

Already down to two? See Spaces vs Front.

Two different products, one sentence each

• Front is a customer operations platform — shared inbox, ticketing, knowledge base, analytics, its own Autopilot AI agent and Copilot — priced per seat, where email, SMS, live chat, social channels and (as a paid add-on) WhatsApp land in one queue that people and AI agents work together. (pricing, external agents)
• Spaces is messaging infrastructure for AI agents: one REST API and one MCP server that let the agent you already use — Claude, Grok, ChatGPT, Cursor or your own code — read and reply to conversations on the Instagram, WhatsApp, LinkedIn and Messenger accounts a business already has, inside each platform's limits, priced per connected account. (pricing, llms.txt)

The short version: Front is where your team works conversations. Spaces is how your agent reaches the chat accounts.

Spaces vs Front, head to head

Price assumption: a small team of 5 people whose customers write in on WhatsApp, Instagram, Messenger and LinkedIn — on Spaces, that is 5 connected accounts (say one WhatsApp number, one Instagram profile, one Facebook account for Messenger and two LinkedIn profiles); on Front, it is 5 seats on Professional, the lowest plan that includes social channels and the WhatsApp add-on. Spaces prices are from spacesos.com/pricing; Front prices are from front.com/pricing. Both checked 11 November 2026, excluding tax. Meta's WhatsApp costs vary by country and message type and are not estimated. Your own AI agent's model costs are not in either figure.

This is not a like-for-like price. Front's seats buy a full help desk for five people — email, ticketing, reporting, a knowledge base — which Spaces does not include. Spaces' price buys five chat accounts an agent can work, including LinkedIn, which Front does not list. If your people need the help desk, Front's price is the price of that. If an agent is doing the answering, you may not need the seats.

Where the difference shows up

1. Front now welcomes your agent — inside Front

Front's "External agents" let you connect an agent built with Claude, Codex, Sierra, Decagon and others, give it a name and role, assign it tickets, @mention it and hand off between people and agents. Front says connecting an external agent "is included on all Front plans". (external agents)

That is a real option, and we would not pretend otherwise. The question is where the conversation lives. In Front, your agent works the channels Front has connected, under Front's seat-based workspace. With Spaces, your agent connects straight to the business's chat accounts — including LinkedIn and a WhatsApp number linked by QR — with no help desk in between. (llms.txt)

2. Both have MCP servers — for different jobs

Front's MCP server (https://mcp.frontapp.com/mcp) lets an assistant search and read conversations across every Front channel, draft and send replies on the conversation's native channel, post internal comments, tag, assign, change status and update contacts — each action attributed to a Front teammate and limited to that teammate's role. It works with Claude and ChatGPT/Codex through their directories, or any MCP client through a private developer app. (help article, developer docs)

Spaces' MCP is built for the agent doing the messaging: read chats, reply, start a chat where allowed, schedule a message for a local time, run routines triggered by a new message, a keyword or no reply after N hours, require a person to approve sends, or pause every send at once. It is on every plan, including Free, and an agent can set Spaces up itself from https://www.spacesos.com/agents. (pricing, llms.txt)

Rule of thumb: Front's MCP gives an agent your help desk. Spaces' MCP gives an agent the chat accounts.

3. Channels: email-first vs chat-first

Front is strongest where email is the centre of customer work, and its Professional plan adds SMS, social and WhatsApp. LinkedIn does not appear on Front's pricing page or its omnichannel page, and Front's Starter plan supports only one channel type (email, chat or SMS). (pricing, omnichannel)

Spaces does not do email as a live channel. It gives one agent the inboxes on Instagram, WhatsApp, LinkedIn and Messenger, plus TikTok for posts and comments, through one API and one MCP server (/mcp, or /mcp/whatsapp, /mcp/instagram, /mcp/linkedin, /mcp/messenger). Facebook Pages is coming soon. (llms.txt)

4. WhatsApp: Meta-billed add-on or a QR link

On Front, WhatsApp is a native channel add-on for WhatsApp Business numbers on Professional and Enterprise, billed at "Meta-billed WhatsApp costs + 20% admin fee", and you can start conversations by sending WhatsApp message templates from Front's composer. (pricing, WhatsApp integration)

Spaces links the WhatsApp number you already use by QR code, the same way you link WhatsApp on a computer, and Spaces says that on this connection there is no Meta approval, no message templates and no Meta message fees, and the number keeps working on your phone (Spaces WhatsApp API page). The trade-off: Spaces is for answering people and following up with people who know the business. A new WhatsApp chat only goes to someone who has messaged the number before or is marked opted in, and template broadcasts to large lists are what the official WhatsApp Business Platform is for. (llms.txt)

5. Pricing: per person or per account

Front is per seat: Starter $25 a seat a month billed annually ($35 monthly, up to 10 seats, single channel type), Professional $65 ($85 monthly, up to 50 seats, omnichannel), Enterprise $105 (annual only). Autopilot is from $0.39 per conversation; Copilot is $20 a seat a month on Starter and Professional; extra Core API rate limit is $200 per 100 requests a minute. (pricing)

Spaces has a Free plan — $0, no card, 1 connected account and 50 actions a day (sending stops until midnight at the limit; reading keeps working; no sequences or webhooks). Pay as you go is $9 per connected account a month, prorated, with 1,000 actions per account pooled across the workspace, then $5 per 1,000 ($4 above 100,000 extra, $3 above 1,000,000). Reading is always free, and you can set a monthly usage cap ($25 suggested). An action is a send, reply, new chat, post, comment, like, follow, invitation or profile lookup. The API and MCP are on every plan. (pricing)

The more people you add, the more Front costs; the more accounts and messages you add, the more Spaces costs.

6. Limits that protect the account

Front's limits are about its platform: MCP tool calls per minute by plan, Core API limits, and channel rules set by each provider. (developer docs)

Spaces' limits protect the chat account itself, because automated use of an existing account is what platforms watch. Every plan has per-channel daily limits, pacing and a four-week warm-up. For up to 24 hours after a WhatsApp account connects, reconnects, or is disconnected and connected again, Spaces does not start new chats or outreach. Replies in chats that already exist still go out. Other channels have no reply-only window: the warm-up limits apply from the first day, and replies to people who wrote in go out immediately. Replies to someone who just wrote in are never held back by daily limits. This lowers the risk of a platform restricting an account; it does not remove it. (limits, safety, llms.txt)

Choose Spaces if

• You are building or running an AI agent that answers customers itself on WhatsApp, Instagram, LinkedIn and Messenger.
• You need LinkedIn messages in the same place as the other chat apps.
• You want to link the WhatsApp number already in use by QR code, without a Meta-billed add-on.
• You would rather pay per connected account than per person.
• You want limits, pacing, warm-up, approvals and a pause switch handled for every account, and a Free plan to start.

Stay with Front if

• Email is the centre of your customer work.
• Several people share one queue and need assignments, rules, SLAs, analytics and a knowledge base — a staffed help desk is the better fit.
• You want your agents (Front's Autopilot or your own) to work inside the help desk your team already uses, with Front's Compass and QA watching them.
• You need SMS, voice or Slack in the same queue.

Some teams will use both: Front for the email help desk, Spaces for an agent working the chat accounts Front does not list, such as LinkedIn.

FAQ

What is the best Front alternative for an AI agent?
If your agent should answer customers directly on WhatsApp, Instagram, LinkedIn and Messenger, Spaces is the closest fit: one API and one MCP server, priced per account. If you still want a shared help desk for people, Trengo and Callbell are nearer swaps.

Can I bring my own AI agent to Front?
Yes. Front's External agents connect agents built with Claude, Codex, Sierra, Decagon and others, on all plans, and Front's MCP server is at https://mcp.frontapp.com/mcp. Your agent then works the channels Front has connected. (external agents, MCP docs)

Does Front support LinkedIn messages?
LinkedIn is not listed on Front's pricing or omnichannel pages, which name email, chat, SMS, social channels such as Facebook, Instagram and X, WhatsApp and Slack. Spaces connects LinkedIn profiles. (pricing)

How much does Front cost?
Per seat a month: Starter $25 billed annually ($35 monthly), Professional $65 ($85), Enterprise $105 (annual only). WhatsApp is an add-on at Meta's costs plus 20%; Autopilot is from $0.39 per conversation. (pricing)

How much does Spaces cost?
Free for 1 account and 50 actions a day, with no card. Then $9 per connected account a month, with 1,000 actions per account pooled, and $5 per 1,000 extra actions. Five accounts within included actions are $45 a month. (pricing)

Is Spaces a help desk?
No. Spaces has no ticketing, SLAs or seat-based team workspace. It is the connection between your agent and the chat accounts, with hand-over to a person when a conversation needs one. (llms.txt)

Can I keep my WhatsApp number if I move to Spaces?
Yes. Spaces links the number you already use by QR code, and the number keeps working on your phone. (Spaces WhatsApp API)

Will connecting an AI agent get my accounts banned?
Every platform has its own rules. Spaces keeps each account inside daily limits, paces activity and warms new accounts up over four weeks. That lowers the risk but cannot remove it. See sending limits and account safety.
