Digest alternatives
2 open-source projects that already do this job. Free to use - not free to run, which is what the numbers on the right are for.

What you give up either way
- Polished, wide catalogue of pre-built source integrations and edge-case parsing
- Deliverability tuning and email-sending scale (bulk sending, bounces, ISP relationships)
- UX polish (sharing links, templates, mobile preview, sample digests)
- Operational reliability and monitoring at scale (retries, rate-limit handling across many providers)
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Digest, and it does not prove anyone has run it for a month. How we decide.
