licenseMIT

installDocker Compose on a Linux VM, followed by environment, database, reverse-proxy and TLS configuration
dataApplication data in PostgreSQL, queues/cache in Redis, and attachments on local disk or S3-compatible/cloud object storage

A mature team inbox with internal notes and ticket owners; it feels like support software because it is.
licenseAGPL-3.0
runsyour server
installDeploy the Docker Compose/Portainer stack or install supported Linux packages
dataTicket and user data in PostgreSQL, search indexes in Elasticsearch, and attachments/backups in Docker volumes or server storage

Shared mailboxes, internal notes and assignments without seat fees; chat-style polish is traded for server care.
licenseAGPL-3.0
runsyour server
installInstall on a PHP/MySQL host with its web installer, or deploy a community Docker image
dataMailboxes, users and conversation metadata in the configured SQL database, with attachments in application server storage
the catch vs MissiveIts shared-mailbox workflow is less fluid than Missive's chat-style collaboration, and advanced modules plus server care add friction.
setupA web server/database plus IMAP/SMTP credentials; several advanced channels and features require separate modules

Assignments, comments and shared queues in a clean interface; the Frappe stack is the hidden teammate.
licenseAGPL-3.0
runsyour server
installRun Frappe's easy-install script against the stable container image on a Linux server
dataTickets in the Frappe site database, with public and private attachments in the site's files directories
the catch vs MissiveIt turns collaborative email into a conventional support queue and adds a Frappe stack to maintain.

why people still pay for Missive
People still pay for Missive because an email client can be rebuilt; operating a trusted mail service with excellent deliverability cannot. The recurring cost buys IMAP quirks, OAuth, MIME, threading, search, attachments, offline sync, notifications, secure storage, and provider changes, not just the visible interface. If none of that applies to you, any pick above saves $216 a year.
