Omni-channel customer engagement platform for developers who want automated user journeys, broadcasts and message templates they can self-host.
Dittofeed sends messages to users across email, mobile push, SMS, WhatsApp and Slack from a single place. It is a developer-friendly alternative to OneSignal, Customer.io and Segment Engage, built for teams that have outgrown volume-based pricing and want customer data to stay inside their own infrastructure.
User data arrives through Segment, reverse ETL or the Dittofeed API. From there you build segments with multiple operators, design templates in HTML and MJML or in the low-code editor, and hand delivery to an email provider such as Sendgrid or Amazon SES.
The dashboard spans the whole messaging lifecycle.
- Journey builder: a graphical interface for one-off broadcasts and automated event-based journeys.
- Segmentation: define user segments and group people into companies, clubs or teams.
- Templates: write email in your own editor and commit it to git instead of an unversioned web IDE.
- Testing SDK: exercise messaging campaigns in CI rather than manually checking them in production.
- Embedded components: place the journey, segment and template builders inside your own app, offered through a separate licensed codebase.
- Analytics: track and analyze message performance from the dashboard.
Deployment runs on Docker Compose, with a one-click Render option and a walkthrough covering a first message end to end. Self-hosting keeps sensitive personal data inside your own network, and a hosted trial exists for anyone evaluating the product first.
