Best Open-Source Intercom Alternatives (2026)
2 self-hostable, open-source projects that replace Intercom — without usage-based pricing that surprises. Each is scored for how hard it is to self-host, with one-click deploy options where they exist.
Intercom's usage-based pricing (resolutions, seats, message volume) makes bills hard to predict and they can spike as you grow or as conversation volume swings. Self-hosting removes the per-resolution metering and keeps customer chat history on your own infrastructure.
Our picks at a glance
Difficulty 3/5 versus erxes at 5/5, plus One-Click and Kubernetes deploy options.
Unifies sales, marketing, and support in one experience-operating-system, the broadest scope of the two, matching Intercom's all-in-one ambition.
Both offer managed hosting, but Chatwoot's far larger community makes its hosted option the safer bet.

What to look for: The allowed field is small and lopsided, so weigh scope against operational cost: Chatwoot is a focused live-chat and support desk, while erxes bundles sales, marketing, and support into one platform that is heavier to run. Note erxes is rated 5/5 difficulty, the hardest in any of these guides, so be honest about whether you have the ops capacity before choosing it over Chatwoot.

The verdict
For most teams replacing Intercom, Chatwoot is the right call: it directly covers live chat and support, is far easier to operate, and has the momentum. Reach for erxes only if you genuinely want a combined sales/marketing/support platform and can absorb its 5/5 self-hosting difficulty.
