Self-Hosted Alternatives to Zapier

Zapier connects web apps with trigger-and-action workflows without code. Because pricing scales with the number of tasks run, busy automations get costly fast, and every connected account hands credentials to a third party; self-hosted engines run unlimited flows next to your own data.
