A proper support inbox with chat, email and a help center; free software, billable server chores.
licenseMIT
runsyour machine or their cloud
installHosted signup or Docker Compose
dataConversations, contacts and configuration in PostgreSQL; Redis handles jobs and cache; attachments use local disk or configured object storage
the catch vs IntercomIt is weaker than Intercom in proactive messaging, AI automation, product tours, customer-data segmentation and the breadth of supported channels and integrations.
setupSelf-hosting requires a VM or Docker, PostgreSQL, Redis, SMTP, persistent or object storage, HTTPS, backups and upgrades

runsyour machine or their cloud
installHosted signup or Docker Compose, Portainer or OS package
dataTickets and users in PostgreSQL, queue and cache in Redis, search in Elasticsearch or OpenSearch, and attachments in filesystem or object storage
the catch vs IntercomIt is fundamentally a ticketing system, not Intercom's polished website messenger, outbound engagement and AI-support platform.
setupSelf-hosting normally means Docker plus PostgreSQL, Redis, Elasticsearch or OpenSearch, mail channels, a domain and backups

licenseApache-2.0

- messaging infrastructure, AI resolution, product tours, integrations, and enterprise operations
- omnichannel integrations
- large-scale deliverability
- AI resolution tuning
- enterprise routing and compliance

why people still pay for Intercom
People still pay for Intercom because support software survives because missing or misrouting one customer message is expensive and every channel behaves differently. The recurring cost buys message delivery, webhooks, threading, identity, permissions, attachments, notifications, spam, search, uptime, and retention, not just the visible interface.
