Reddit Keyword Monitoring Tools Compared (2026 Prices)
Keyword monitoring on Reddit means getting told, quickly, when someone mentions your brand, a competitor or the problem you solve. It is one of the best sources of warm leads and honest feedback. This guide compares the tools people use in 2026, with prices taken from each vendor's own page, and shows how to build your own alert if you prefer.
The tools at a glance

Quick read: F5Bot and KWatch are the cheapest way to start. Syften is built for speed on community sites. Octolens and Brand24 are for teams that want many networks and dashboards in one place. If you only care about Reddit and Hacker News, the free tiers may be all you need.
Write rules that do not drown you
Most monitoring fails on noise, not coverage. A few rules help with any tool:
- Use phrases for common words. If your product is called "Notion" or "Linear", alert on "notion app" or "linear.app", not the bare word.
- Add misspellings and the domain. People type brand names wrong and paste links.
- Exclude known noise. Add negative terms for homonyms, job posts or your own team's usernames.
- Watch problems, not only brands. "alternative to X", "X is too expensive" and "how do I Y" catch buyers who have not heard of you yet.
- Route by intent. Send complaints to support, buying questions to sales, and everything else to a digest.
How fast do you need it?
Reddit threads move fast. A helpful reply in the first hour gets seen; one on day three rarely does. If you reply to people, pick a tool or schedule that checks at least every 15 minutes. If you only track volume or sentiment, a daily digest is fine and much cheaper.
Build your own alert
If you already have an API, a small script covers the basics. This one polls a search endpoint, remembers what it has seen in SQLite, and posts new hits to a Slack webhook.
import sqlite3, requests
KEY, SLACK = "YOUR_KEY", "https://hooks.slack.com/services/..."
TERMS = ["yourbrand", "alternative to competitor"]
db = sqlite3.connect("seen.db")
db.execute("create table if not exists seen (id text primary key)")
for term in TERMS:
r = requests.get("https://scrapeio.com/v1/reddit/search",
params={"query": term, "sort": "new"},
headers={"x-api-key": KEY}).json()
for post in r["data"]["items"]:
if db.execute("select 1 from seen where id=?", (post["id"],)).fetchone():
continue
db.execute("insert into seen values (?)", (post["id"],))
requests.post(SLACK, json={"text": f"[{term}] {post.get('title')} {post.get('url')}"})
db.commit()
Run it from cron every 15 minutes. Keep the seen table forever, or prune IDs older than a month.
Budget formula
For a DIY setup, monthly calls = keywords × checks per day × 30. Ten keywords every 15 minutes is 10 × 96 × 30 = 28,800 calls a month. At ScrapeIO's Starter rate of $1.88 per 1,000 that is about $54; at the Growth rate of $0.99 per 1,000 it is about $29. Repeats that hit the cache are not charged, so the real number is often lower. Compare that with the tool prices above: a hosted tool wins if you want a dashboard and no code, DIY wins if you want alerts inside your own product.
Doing it with ScrapeIO
Use the Reddit search API for site-wide keywords and the subreddit search API to watch a term inside one community. When an alert fires, pull the thread with the post comments API so your team sees the context. The same script works for other networks by swapping the path; see the Reddit endpoints and docs.
