Syften watches roughly 17 platforms with keyword, domain, and username monitors, but every tier carries a hard daily result cap starting at $29.95/mo. Redditapis is Reddit-native, priced flat by monitor slot from $19/mo, with no daily result cap.
Syften or Redditapis: which should I use for Reddit monitoring?
Use Syften when you need to monitor platforms beyond Reddit in one place; every Syften tier carries a hard daily result cap (100 to 500) starting at $29.95 a month. Use Redditapis when Reddit is the job: domain-level watches, flat pricing by monitor slot from $19 a month, 10,000 alerts a day per monitor, and webhook, Slack, and Discord delivery on every paid tier, built on a 59-endpoint Reddit-native REST API.
The short answer
Syften watches around 17 platforms from one filter set. If Hacker News, GitHub and Slack communities matter as much as Reddit does, that breadth is the product, and no Reddit-only tool replaces it. The trade is a daily results cap that every platform draws from at once.
One platform, no shared daily cap, and a per-monitor allowance of 10,000 alerts a day on the entry plan. The same account also calls the underlying Reddit API directly, so monitoring and reading sit behind one key rather than two vendors.
Reddit Monitoring Score, our own weighting of Reddit coverage, alert allowance, delivery options and price: Redditapis 9 of 10, Syften 6 of 10. Syften scores higher than that on any question wider than Reddit, which is the whole point of the split.

| Dimension | Syften | Redditapis |
|---|---|---|
| Platform coverage | About 17 platforms: Reddit, Hacker News, X, Bluesky, Mastodon, GitHub, forums, and general web | Reddit only, with subreddit, author, score, keyword, and domain filters purpose-built for it |
| Pricing model | Entry $29.95/mo, Standard $49.95/mo, Pro $119.95/mo, on a dual meter: filters you may keep running and results delivered per day, counted separately in a Communities pool and a Web pool | $19 to $199/mo flat by monitor slot (15 to 500 monitors), no results-per-day cap |
| Daily result cap | Communities results, where Reddit sits: 100/day Entry, 200/day Standard, 500/day Pro, plus 3, 20 or 100 filters. Web is metered apart at 5, 20 or 50 results. What happens once a cap is reached is not published | 10,000 alerts a day per monitor on Starter, 25,000 on Growth, 50,000 on Pro, 100,000 on Scale. The count is per monitor rather than pooled across platforms, matches beyond it are still recorded and shown, and it resets at midnight UTC |
| Reddit latency | "At most a 1-minute delay" for Reddit, per Syften's own pricing page | As fast as 60 seconds on Starter and 30 seconds from Growth up. Those are floors, the fastest a tier may poll, and a monitor can be set slower |
| Delivery channels | Email and RSS on every paid tier. Slack and API start at Standard, $49.95/mo; webhooks and MCP only at Pro, $119.95/mo. Discord and Telegram are not published anywhere on its site | Webhook, Slack, and Discord delivery on every paid tier, starting at $19/mo |
| Monitor types | Keywords, domains and URLs, and specific usernames, across ~17 platforms | Keyword, subreddit, author, score, and domain filters, matched against Reddit's own posts. A keyword with no subreddit watches all of Reddit, capped at 1 sitewide watch on Starter, 3 on Growth, 10 on Pro, and 25 on Scale |
| Posts vs comments | Covers both posts and comments across its monitored platforms | Posts on every tier. Comments from Growth, $49/mo, and a comment monitor has to name at least one subreddit. All-of-Reddit watches stay post-only |
| Underlying data access | An alerting product; API access ships from Standard, $49.95/mo | Monitoring runs on top of the full 59-endpoint Reddit REST API: search, comment search, users, communities, write, vote, and DM |
Redditapis monitoring runs on top of the 59 REST endpoints in the Redditapis OpenAPI spec at docs.redditapis.com/openapi.json. Compare tiers on the pricing page.
Neither tool wins every row. The right choice depends on whether you need broad multi-platform coverage or Reddit monitoring at a flat price with a far larger daily alert allowance.

Redditapis
How it works
A far larger allowance to plan around: 10,000 alerts a day per monitor at the entry plan, not 100 to 500 shared across every platform. Add a subreddit and a keyword filter, point it at a webhook, Slack channel, or Discord channel:
curl "https://api.redditapis.com/api/monitor/add" \
-H "Authorization: Bearer YOUR_API_KEY" \
-d '{"subreddit":"marketing","q":"your brand"}'Full endpoint paths and parameters live in the API docs. See the full monitoring product on the Reddit monitoring API page.

Two things decide whether an alert is worth acting on, and neither is the tool. Which communities you watch comes fromthe ranked subreddit list pulled from the API, and whether a thread is still moving when you see it depends onwhen the subreddit is actually awake. For the cost and latency side of the comparison, theprovider benchmarkhas the measured numbers.
Method
Every competitor figure on this page is read from the vendor's own published pricing page on the date shown, never from a roundup or a review site. Where a vendor states a range rather than a number, the range is quoted rather than averaged.
Per our own delivery logs, Redditapis delivered 34,520 alerts to customer webhooks in the 30 days to 25 August 2026, across 72 registered subreddits. That is the figure our own monitoring writes, not a projection, and it is the one number on this page no competitor can check.
We do not publish a head-to-head latency benchmark against Syften. Running one fairly needs both accounts watching the same keywords in the same subreddits over the same window, and we have not done that. Syften states at most a 1-minute delay for Reddit, and we quote their figure rather than guessing at ours.
Free, email only, keyword only, and genuinely good at the one job it does. What it cannot do is tell you anything about the thread a keyword landed in, or hand a match to code. If the alert is the end of the workflow, F5Bot is enough. If the alert is the start of one, it is not. The F5Bot comparison goes through the follow-up questions an email cannot answer.
A broad social listening suite where Reddit is one source among many, priced for marketing teams rather than for developers. If you want brand coverage across the open web, that breadth is the point. If you want Reddit threads arriving in a webhook, it is a lot of product to carry for one of its sources.
Count your platforms first. More than one and the answer is Syften or Mention. Reddit only, and the next question is whether a daily cap will bite: if you watch busy subreddits, a shared 100 to 500 results a day is the constraint that decides it, and a per-monitor allowance of 10,000 is not.
Per our own delivery logs, Redditapis delivered 34,520 alerts to customer webhooks in the 30 days to 25 August 2026, across 72 registered subreddits. Comparison pages usually stop at the price table, because the vendor is the only party who can see this number. It is worth stating plainly what it is: volume actually delivered, not capacity we are entitled to sell.
A delivery is not fire and forget. Each one records its attempt count, the time of its next retry, and the last error the receiving endpoint returned. If the endpoint stays unreachable for the whole retry chain, the delivery is marked dead rather than quietly dropped, so a gap in your alerts is something you can query afterwards instead of something you have to infer. An email-only monitor has nowhere to put that state, which is the practical difference when a receiver breaks at 3am.
A cap of 100 to 500 results a day sounds generous until you notice what it is shared across. One busy subreddit during a launch can produce that many matching comments on its own, and on a shared pool every one of them is spent against Hacker News, GitHub and Slack coverage too. The failure is quiet: you do not get an error, you get a day that looks calm because the cap was reached at lunchtime. A per-monitor allowance of 10,000 a day removes the question rather than moving it.
Syften is a multi-platform listening tool that monitors keywords, domains and URLs, and usernames across roughly 17 sources, including Reddit, Hacker News, X, and the general web. Pricing is Entry $29.95, Standard $49.95, and Pro $119.95 a month, and every tier carries a hard daily result cap.
For Reddit specifically, a Reddit-native monitor like Redditapis. Each monitor sends up to 10,000 alerts a day on the entry plan, rising to 100,000 on Scale, and that allowance is per monitor rather than shared with other platforms, so a busy subreddit has far more room than a pooled 100 to 500 a day. It delivers to webhook, Slack, or Discord on every paid tier from $19 a month, half the price of Syften's Entry plan.
Use Syften when you need to monitor platforms beyond Reddit in one place. Use Redditapis when Reddit is the job: it also supports domain-level watches, plus flat pricing and 10,000 alerts a day per monitor at the entry plan, where Syften's 100 to 500 results a day are shared with every other Communities platform it watches for you.
Yes. Syften publishes a daily results cap in its Communities pool, where Reddit sits alongside Hacker News, GitHub and podcasts: 100 a day on Entry, 200 on Standard, and 500 on Pro. What happens to matches once that cap is reached is not published, so we will not tell you they are dropped. Redditapis publishes its own number instead: 10,000 alerts a day per monitor on the entry plan, up to 100,000 on Scale, with matches beyond it recorded and shown rather than dropped.
Syften states at most a 1-minute delay for Reddit on its own pricing page. Redditapis polls about every 60 seconds on its Starter tier and about every 30 seconds from the Growth tier up, so the two are broadly comparable at entry level and Redditapis is the faster of the two from Growth onward.
Yes, Syften supports domain and URL monitoring alongside keywords and usernames. Redditapis matches this at the domain level too, filtering posts by the domain a submitted link points to, though Syften's monitoring spans roughly 17 platforms where Redditapis is Reddit-only.
Syften is Entry at $29.95 a month (100 results/day), Standard at $49.95 a month (200 results/day, adds Slack, AI filtering, and API), and Pro at $119.95 a month (500 results/day, adds webhooks and MCP). Prices are published on syften.com.
