Open Source Intercom Alternatives in 2026: What They Cost Your Team to Run

Chatwoot is the closest open source Intercom alternative for most teams: five Intercom seats cost $145 a month on annual billing, while Chatwoot’s free Community edition prices the whole team as one server instead. Pick Zammad if your support runs on tickets and SLAs, and FreeScout if it runs on email and you want the smallest server. Libredesk, Tiledesk and Chaskiq fit narrower jobs, and Papercups, Rocket.Chat and Opencom are covered at the end.

The catch most guides skip is that “no seat fees” holds only for Chatwoot’s free edition. Captain AI, voice calls and custom branding need Chatwoot’s Premium plan on a self hosted install, and that is $19 per agent per month. So the real choice is which features you need, and who runs the server.

We build Selfhost.dev, which runs Chatwoot as a one-click template, so we have a stake in one entry below. Check our server figure against the calculator rather than taking it from us.

Who this isn’t for: a one or two person team on live chat alone. Chatwoot’s own free cloud plan covers that case, and it is explained further down.

Why do teams leave Intercom?

Teams leave Intercom because the bill has two meters that both grow. Seats run $29 to $132 per seat per month on annual billing, or $39 to $139 billed monthly. Fin, Intercom’s AI agent, adds $0.99 for every conversation it resolves. Hiring raises the first meter, and a busier inbox raises the second.

The seat meter. On Intercom’s pricing page, Essential is $29 per seat per month on an annual plan and $39 month to month, with one full seat as the minimum. Advanced is $85 or $99, and Expert is $132 or $139. A five person support team on Essential pays $145 a month annually, or $195 monthly, before any AI.

The outcome meter. Fin AI Agent costs $0.99 per Fin outcome on every plan. Three hundred resolved conversations a month adds $297. The better Fin performs, the larger that line gets.

The add-ons. Copilot, the inbox assistant, is $29 per agent per month billed annually ($35 monthly). Proactive Support Plus, which carries product tours, checklists and surveys, is $99 a month for 500 messages. The Pro add-on starts at $99 a month.

Two growing meters is what makes a bill hard to forecast. We measure that as Bill Variance, the gap between a quiet month and a busy one. An open source inbox on one server takes the seat count out of the bill entirely, and the AI meter with it, unless you add AI back.

Intercom prices the person answering. A server doesn’t know how many people are logged in.

What do you give up by leaving Intercom?

You give up a finished AI agent, product tours, and compliance paperwork that arrives with a plan. Intercom sells all three ready to switch on, and no open source helpdesk matches all of them out of the box. If any one of them is why you bought Intercom, it may be a reason to stay.

• Fin, already trained and running. Intercom bundles Fin AI Agent into every plan and charges per outcome. If Fin resolves a large share of your volume today and nobody on your team wants to tune an AI setup, that is a real reason to stay.
• Product tours and in-app messages. Proactive Support Plus covers posts, checklists, product tours, surveys and series campaigns. If your onboarding runs on in-app tours, an open source inbox replaces the inbox, not the tours.
• Compliance on the plan. Intercom’s Expert plan lists SSO and identity management, HIPAA support and SLAs. If a security review needs those signed on day one, buying them is faster than building them.
• One vendor for all of it. One contract, one support line, one invoice. Some teams value that more than the saving.

If none of those four is your reason for paying, the rest of this page is about what replaces the inbox, and what it costs.

How do the open source Intercom alternatives compare?

Chatwoot is the closest match to Intercom: a shared inbox for live chat, email, WhatsApp and social channels under an MIT licence. Zammad and FreeScout are helpdesks closer to Zendesk and Help Scout. Libredesk, Tiledesk and Chaskiq each cover part of Intercom. The table ranks them on cost to run, not on feature count.

Every option below is free to download. What separates them is the monthly bill and the list of jobs that lands on your team. The first row is the only one where that list is just the inbox.

Not every project here is open source in the strict sense. Chaskiq’s Commons Clause makes it source-available, and Tiledesk keeps its enterprise features in private images. Both are listed because both are self hostable and built to replace Intercom.

Chatwoot

Best for: teams replacing Intercom’s shared inbox across live chat, email, WhatsApp, Instagram and Facebook.

What it costs to run: the Community edition is free, and on Selfhost.dev it runs on a European 8 GB server for $23.36 a month, whatever the agent count.

Key difference: Chatwoot is built as an Intercom and Zendesk alternative, and it ships a built-in Intercom importer.

What it does worse: Captain AI, voice calls, custom branding, agent capacity and roles need Chatwoot’s Premium plan on a self hosted install, at $19 per agent per month.

One thing you won’t find on their own page: several guides call self hosted Chatwoot “free” or “no paywall”, and one says it has no AI. Both are half right: the AI exists, and it sits behind the per-agent licence.

Zammad

Best for: support teams whose work is tickets, queues and SLA policies rather than chat.

What it costs to run: the AGPL-3.0 code is free. Zammad’s own docs set the minimum at 2 CPU cores and 6 GB of RAM, plus 4 GB more if Elasticsearch runs on the same server.

Key difference: Zammad is a helpdesk first and a chat tool second, so it sits closer to Zendesk than to Intercom.

What it does worse: it needs the largest server of any project here.

One thing you won’t find on their own page: at 40 agents, Zammad’s docs ask for 6 cores, so the server grows with the team even though the licence doesn’t.

FreeScout

Best for: teams whose support runs on email and who want something close to Help Scout.

What it costs to run: the AGPL core is free, and FreeScout says it deploys “even on a shared hosting”.

Key difference: FreeScout is an email inbox with unlimited agents and mailboxes, not a messenger.

What it does worse: live chat, the feature most people buy Intercom for, is a paid module sold as a lifetime licence per FreeScout install.

One thing you won’t find on their own page: the live chat module page shows a purchase button but no price, so cost it before you plan around it.

Libredesk

Best for: small teams that want email, live chat and WhatsApp in one shared inbox.

What it costs to run: free under AGPL-3.0, distributed as a single binary, with Postgres and Redis alongside it.

Key difference: one Go binary instead of a Rails stack with separate workers.

What it does worse: at 3,000 GitHub stars, it has the smallest community of the four inbox-style picks, so fewer guides and answers exist.

One thing you won’t find on their own page: Libredesk’s launch post on r/selfhosted pitched it against Chatwoot itself, not only Intercom and Zendesk, and its README describes no paid tier at all.

Tiledesk (H3)

Best for: teams that design chatbot and LLM flows and hand conversations to people when the bot stops. What it costs to run: MIT licensed, with MongoDB underneath, and production installs run on Kubernetes with Helm. Key difference: Tiledesk starts from a bot design studio, where Chatwoot starts from the inbox. What it does worse: enterprise features ship as private Docker images that need credentials from Tiledesk. One thing you won’t find on their own page: the README labels Docker Compose for “development, POCs, and trials”, so a small production install is more work than it first looks.

Chaskiq

Best for: teams that use Intercom’s outbound side as much as its inbox: campaigns, banners and guided tours.

What it costs to run: no licence fee; it is source-available under AGPL-3.0 with the Commons Clause, on Ruby, Postgres and Redis.

Key difference: Chaskiq covers marketing messages as well as support, which is closer to Intercom’s full product.

What it does worse: the Commons Clause restricts selling the software, so commercial use may need its separate licence.

One thing you won’t find on their own page: Chaskiq’s code hasn’t moved since 30 June 2026, while Chatwoot, Zammad, FreeScout and Libredesk all had commits on 6 or 7 October. Check its activity before you build on it.

Also considered, and why they’re not on this list

Papercups: no commits since 15 February 2024.

Rocket.Chat: a team chat platform first, with customer messaging added on.

Opencom: new and promising, at 62 stars.

Live Helper Chat: Apache-2.0 and active, built around high-volume live chat; worth a look if chat is your only channel.

Usertour: product tours only, not an inbox.

Formbricks: surveys, not support.

Frappe Helpdesk, osTicket, UVdesk and OTOBO: ticketing systems that replace Zendesk more than Intercom.

Is an open source Intercom alternative actually cheaper?

Yes, from the third agent on a European server. Five Intercom seats with 300 Fin resolutions cost $442 a month. Chatwoot on Selfhost.dev’s one-click template costs $23.36 on a European 8 GB server, at 5 agents or 50. On a US server at $119.28, the flat bill wins from the fifth agent.

The AI line is where Intercom’s bill runs away. Fin charges $0.99 for every conversation it resolves. A five person team with 300 resolutions pays $145 in seats plus $297 in Fin: $442 a month. Chatwoot’s free edition runs the same inbox for $23.36. When you want an AI agent, add Captain: the Premium licence for five agents plus the server comes to $118.36, about a quarter of the Intercom bill. Captain runs on OpenAI’s GPT models, and Chatwoot doesn’t say whether that usage is billed separately, so confirm it with them.

What the $23.36 covers. The whole server, not a share of one. Postgres, Redis and the Sidekiq worker run connected behind HTTPS, and the bill stays the same when you hire. Rent a bare 8 GB server yourself and the monthly price is only the start: the installing and connecting are still on your team.

Seat pricing against server pricing is the same split we found in Vaultwarden vs Bitwarden: per-person pricing wins while the team is tiny, and a flat server wins as it grows.

What does running a self hosted Intercom alternative take?

A self hosted Intercom alternative needs more than the free download. For Chatwoot, that means four services kept running on one server, plus the security and mail settings around them. Guides that call it free leave out that work, and it is exactly the work Intercom’s per-seat fee pays someone else to do.

What Chatwoot needs to run (per Chatwoot’s requirements):

• A Linux server: 4 GB of RAM and 4 cores is the stated minimum, for up to 10,000 conversations a day
• PostgreSQL, the only supported database
• Redis 7 or higher
• The Sidekiq worker, which “can use 1GB+” on a busy server
• TLS, a firewall and an SMTP provider for invites and password resets
• Backups, and someone who notices when any of it stops

Google’s AI Overview for this search names the same work: server uptime, security updates, database backups and software upgrades.

There are three ways to run Chatwoot:

What stays yours on Selfhost.dev: Chatwoot itself (inboxes, agents, teams and automations), the widget script on your site, your SMTP provider, and your data. We run the infrastructure: the server, the containers, the TLS certificate, the firewall, CPU and memory metrics, and optional whole-server backups at 20% of the server price.

One limitation to plan for: the server is sized when you deploy it, so pick the size you want to grow into.

The part every guide skips is the part we run. Postgres, Redis and the worker arrive connected, behind TLS, on a server sized for the whole team.

Which open source Intercom alternative should you choose?

Choose by what your support runs on. Chatwoot fits teams replacing Intercom’s inbox, Zammad fits ticket queues, and FreeScout fits email. Then choose who runs it: Chatwoot Cloud for one or two agents, your own server if you have someone to run it, and a one-click host if you want the flat bill without the upkeep.

• If your support is live chat, email and social in one inbox, pick Chatwoot, because it is the closest open source match to Intercom and imports your Intercom history.
• If your support runs on tickets, queues and SLAs, pick Zammad, because it is a helpdesk first, and budget at least 6 GB of RAM.
• If your support is mostly email, pick FreeScout, because it runs on the smallest server here, and cost the live chat module first.
• If you have one or two agents on live chat alone, start on Chatwoot Cloud. Chatwoot’s own free tier covers two agents on live chat, up to 500 conversations a month, with thirty days of history. Past any one of those three, it is $19 per agent per month on an annual plan.
• If you have three or more agents (five or more on a US server) and nobody who wants to run Postgres and Redis, run Chatwoot on Selfhost.dev: $23.36 a month on a European 8 GB server, or $119.28 in the US, whatever the headcount.

Your Intercom history can come with you: Chatwoot’s importer brings contacts and conversations, with their message history.

Switching doesn’t mean starting from an empty inbox. Chatwoot’s built-in importer brings your Intercom contacts and conversations across, with their message history.

The importer ships in the Chatwoot version the template pins. Billed by the hour, $0.03 on the European server, so a test import costs cents, not a seat.

The Decision

Pick Chatwoot if Intercom’s inbox is what you’re replacing, Zammad if your support runs on tickets, and FreeScout if it runs on email. Stay on Intercom if Fin already resolves a large share of your volume and nobody wants to run an AI setup. For one or two agents on live chat, Chatwoot Cloud’s free plan is the honest start.

On the European server priced here, one flat server costs less than Intercom’s annual seats from the third agent; on a US server, from the fifth.

If that’s your team, Chatwoot on Selfhost.dev runs it with Postgres, Redis and the worker already connected.
