Email and newsletters decision
Digest
A capable developer can implement a narrow Digest replacement (RSS + inbound newsletter + scheduled AI summaries and email delivery), but reproducing the full commercial product (many pre-built integrations, deliverability at scale, polished UX) is substantial and operationally heavier than a small DIY scope.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Digest alternatives, with the arithmetic →
What a replacement has to do
- Collect posts/newsletters from sources (RSS, social feeds, incoming newsletter email), generate concise AI summaries, compile items into a templated email, and send the scheduled digest while providing basic subscription management and archive/search.
What it still won’t have
- 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)
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal self-hosted Digest service using Node.js (Express), PostgreSQL, Redis, and a worker queue (Bull). Core features in scope: (1) RSS and public feed ingestion (poll endpoints), (2) inbound newsletter ingestion via a single IMAP-inbound mailbox parser, (3) AI summarization using the OpenAI API, (4) a scheduler that composes a templated HTML email per user schedule, (5) email sending via SendGrid/Mailgun, and (6) a small web UI to connect sources, set schedule, preview sample digest, and manage subscribers. Out of scope: broad catalogue of proprietary integrations, multi-tenant scaling beyond one account, advanced deliverability tuning, mobile apps, and paid-plan billing. Include error handling, retry/backoff for external APIs, logging/metrics, database migrations, Docker-based deployment, and unit+integration tests for ingestion, summarization, scheduling, and delivery paths.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
