A Syften alternative that also watches Facebook groups.
Syften covers Reddit, X, Hacker News and dozens of tech communities, with alerts within minutes and a filter language of its own. KeywordWatchr covers fewer sources and checks once a day, but includes Facebook groups, and X without a surcharge.
Why people look for a Syften alternative
Three reasons, each from Syften's own pages.
X costs extra
X is an add-on at $40 a month on Standard and PRO, on top of the plan, and not available on Entry.
No Facebook groups
Syften lists dozens of communities, but Facebook is not among them.
Filters are queries
Narrowing a Syften filter means writing its query language: operators, wildcards, site and author filters.
The short answer
Where Syften fits better, and where KeywordWatchr does.
Choose Syften if …
- Your audience is on Hacker News, GitHub, Stack Exchange, Bluesky, Mastodon or similar communities.
- You want a match within minutes.
- You want a filter language with operators, AI filtering, RSS feeds or an API.
Choose KeywordWatchr if …
- Your customers ask for advice in Facebook groups.
- You want X included in the price, not as a $40 add-on.
- A weekly digest is enough, or a daily one on Pro and Business.
- You would rather fill in a form than write a query.

What sets Syften and KeywordWatchr apart
Three differences that decide which one fits.
Breadth or Facebook groups
Syften reaches far more developer and tech communities. KeywordWatchr reaches public Facebook groups, which Syften does not list.
Minutes or a daily check
Syften delivers Reddit matches within about a minute. KeywordWatchr checks once a day and sends a digest on your schedule, which suits a team that reads its mentions once a day anyway.
A query or a form
Syften filters are written in its own query language. A KeywordWatchr alert is a form: terms, exclusion words, subreddits or groups.
