ChatterSift is an open-source Reddit monitoring app: define keyword monitors across subreddits and get matching posts and comments delivered as alerts. Built as a Django app, HTMX/server-rendered first.
Keyword matching — exact phrases, word boundaries, or regex across post titles, bodies, and comments, with negative filters to kill false positives.
Multi-subreddit monitoring — one monitor configuration covers every community on its list. Scale from five subreddits to five hundred without rewriting a rule.
Instant email alerts — matches delivered to your inbox within minutes. Per-keyword rate limits keep things usable.
Your data, your control — use the hosted SaaS or self-host the open source. Either way, your keywords and match history stay in your stack.
Background processing — Celery workers with retries and back-pressure. The monitor doesn't sleep, and alerts don't pile up.
Open source, MIT-licensed — read it, fork it, extend it. No lock-in.
