Reddit, HN & Bluesky monitoring tools compared
Every listing tool in this space covers Reddit. Almost none cover Hacker News, and fewer still cover Bluesky. We checked six tools' public pricing/feature pages directly (dated below) and led the table with the two columns most of them skip — not the ones that flatter us most.
| Tool | Hacker News | Bluesky | X / Twitter | Entry price | Drafts a reply | |
|---|---|---|---|---|---|---|
| ReplyWell | Yes | Yes | Yes (paid) | Yes (paid) | €0–€19/mo | Yes — disclosed draft |
| Syften | Yes | Yes | Yes | Yes | $29.95/mo | No |
| F5Bot | Yes | No | Yes | No | $0–$79.99/mo | No |
| Brand24 | No | No | Yes | Yes | $199/mo | No |
| Mention | — | — | Yes | Yes | Custom | No |
| SubredditSignals | No | No | Yes | No | $29/mo | No |
"—" means the tool's own pricing/feature page didn't publish a clear answer — not a guess either way. ReplyWell's Reddit + X columns need a paid plan (€19/mo Starter; paid checkout opens soon — today it's a waitlist); Hacker News + Bluesky are on the free tier.
Credit where it's due: Syften also covers HN and Bluesky
Syften is the one tool on this list that matches ReplyWell's Reddit + Hacker News + Bluesky + X coverage — it's a genuinely broad monitoring tool, and if you want mentions surfaced across GitHub, Slack, Mastodon and more too, it covers ground we don't. The difference isn't source coverage; it's what happens after a mention is found. Syften (like F5Bot, Brand24, Mention, and SubredditSignals) surfaces the mention and stops there — none of the five advertise drafting the reply itself on the pages we checked. ReplyWell's one job is the next step: an honest, disclosed reply draft for the threads worth answering, which you post yourself.
How to read the price column
F5Bot and ReplyWell both have real free tiers; the rest start paid. Brand24 and Mention are built for teams monitoring broad brand sentiment across many platforms (Facebook, Instagram, LinkedIn, TikTok, reviews and more) — if that's your job, their price reflects real scale, not padding. Syften and SubredditSignals sit in between: narrower than Brand24, still alert-only.
