What it is
A full open-source marketing automation platform: contacts, segments, lead scoring, landing pages, forms, and multi-step campaigns with real branching — opened but did not click, wait three days, send the other version. The self-hosted equivalent of the marketing half of HubSpot.
What it is good for. Listmonk (Ed.2 #1) broadcasts to a list. Twenty (Ed.9 #1) records who people are. Nothing in the ledger acts when a person behaves a certain way, and for a solo founder that gap is expensive: it is the difference between a list and a funnel. The realistic use here is small and specific — one five-email onboarding sequence in English and the same one in Russian, triggered on signup, whose only job is getting a new user to the first thing the product actually does for them. That is precisely the moment OpenReplay (Ed.9 #3) will show you people never reach. Automation is how you attend to it while asleep.
- GPL-3.0, self-hosted, with no seat limits and no per-contact pricing — the entire economic reason to run it rather than rent it.
- Genuinely mature and actively released: 7.2.0 landed on 2 September, on a roughly two-to-three-week cadence.
- Owns both the sequence and the landing page it points at, so a campaign is one system rather than three glued together.
- The heaviest install on this page: PHP/Symfony with cron jobs it genuinely depends on, and it wants MySQL or MariaDB — a second database engine beside an existing Postgres, with its own backup story in restic (Ed.8 #11).
- It overlaps Listmonk directly. Running both means two subscriber lists drifting apart — pick one and delete the other.
- The interface is from an older era of enterprise software and will cost you a confused afternoon before it costs you nothing.
