F5Bot is a free-to-start email keyword bot across Reddit, Hacker News, and Lobsters. Its free tier allows 5 keywords with alerts within 2 hours, Slack and Discord start on its $49.99/mo Gold tier, and the API and webhooks start on Platinum at $214.99/mo. Redditapis watches all of Reddit for a keyword or a subreddit end to end, with webhook, Slack, and Discord delivery on every paid tier from $19/mo, built on a full Reddit data API.
F5Bot or Redditapis: which should I use for Reddit monitoring?
Both watch all of Reddit for a keyword. Use F5Bot when one bot across Reddit, Hacker News, and Lobsters with email alerts is enough, or when you track many terms sitewide, since it meters keywords rather than watches. Its free tier allows 5 keywords with alerts within 2 hours, Slack, Discord, RSS and JSON start on Gold at $49.99 a month, and the API and webhooks start on Platinum at $214.99 a month. Use Redditapis when Reddit is the job: sitewide or per-subreddit watches with author and score filters, webhook, Slack, and Discord delivery on every paid tier from $19 a month, and a 52-endpoint Reddit-native REST API underneath. Sitewide watches are capped per plan, 1 on Starter up to 25 on Scale, and cover posts rather than comments.
Side by side
F5Bot figures read from its own tier matrix at f5bot.com/tiers on 2026-08-13, which is the authoritative source rather than the homepage cards. Redditapis figures match this site's pricing and monitoring pages.
| Dimension | F5Bot | Redditapis |
|---|---|---|
| What it covers | Reddit, Hacker News, and Lobsters, one keyword bot across all three | Reddit only, with subreddit, author, score, keyword, and domain filters purpose-built for it |
| Reddit coverage | All of Reddit by default. F5Bot's own page says it tracks mentions across posts and comments in every subreddit, with subreddit narrowing available as an advanced filter | Both, and you choose per monitor. Name subreddits to watch them as streams, or leave the subreddit empty and a keyword watches all of Reddit. Sitewide watches are on every tier including the free one, capped at 1 on Free and Starter, 3 on Growth, 10 on Pro, and 25 on Scale |
| Pricing model | Five tiers, metered by keyword count: Free (5 keywords), Silver $9.99/mo (20), Gold $49.99/mo (200), Platinum $214.99/mo (300), Diamond from $500/mo (custom). Annual billing is $109, $549, and $2,364 | $19 to $199/mo flat by monitor slot (15 to 500 monitors), no keyword cap. A sitewide watch uses one of those slots and counts against the tier's sitewide cap as well |
| Free tier | Free forever, no card: 5 keywords, alerts within 2 hours, 10 alerts per keyword per day and 20 across the account. Email only, and common words are rejected. If email is enough, this is free and we are not cheaper | One free watch on every account, no card: 1 keyword across all of Reddit, new posts, checked about every 60 seconds, up to 10,000 alerts a day, delivered to webhook, Slack or Discord. Fewer keywords than F5Bot's five and posts only, but checked in about a minute rather than within 2 hours, and without the 20-alerts-a-day account cap. Naming a subreddit, comment matches and extra watches start at $19/mo |
| Alert channels | Email on every tier. Slack and Discord start at Gold, $49.99/mo (1 integration, 3 on Platinum). Webhooks start at Platinum, $214.99/mo | Webhook, Slack, and Discord delivery on every tier, including the free watch. Paid plans start at $19/mo |
| Delivery guarantee | Not published on their pricing or docs pages | HMAC-signed webhook POST, retried with backoff for up to 21 minutes |
| Posts vs comments | Covers both posts and comments across all three platforms, including sitewide comments | Posts on every tier. Comments from Growth, $49/mo, and a comment monitor has to name at least one subreddit. Sitewide watches stay post-only, because the all-of-Reddit comment listing runs at roughly 100 comments a second and we will not sell what we cannot poll |
| Programmatic access | RSS and JSON feeds start at Gold, $49.99/mo. The API and webhooks are Platinum and above, $214.99/mo, and are marked absent on the Gold column of F5Bot's own tier matrix | Built on the full 52-endpoint Reddit REST API: search, comment search, users, communities, write, vote, and DM, on every tier |
| Result caps | Published, and strict. A per-keyword daily cap of 10, 30, 100 and 500 by tier, plus an account-wide daily alert cap of 20, 100, 5,000 and 200,000. F5Bot's FAQ says a keyword that goes over its limit is disabled until you re-enable it by hand | A daily alert ceiling per monitor: 10,000 on Starter, 25,000 on Growth, 50,000 on Pro, 100,000 on Scale. Nothing is disabled when it is reached, the count resets at midnight UTC and matches over it are still recorded. Price is flat regardless of match volume |
| Detection cadence | Published per tier as alert speed: within 2 hours on Free, within 5 minutes on Silver, instant or scheduled from Gold up | As fast as 60 seconds on Starter and 30 seconds from Growth up. Those are floors, the fastest a tier is allowed to poll, and you can set a monitor slower |
Redditapis monitoring runs on top of the 52 REST endpoints in the Redditapis OpenAPI spec at docs.redditapis.com/openapi.json. Compare tiers on the pricing page.
Neither tool wins every row, and the coverage argument is over: both watch all of Reddit for a keyword now. What is left is how each one meters, and where the alert lands.

Redditapis
How it works
Register a webhook, Slack channel, or Discord channel, and matches arrive as a signed POST instead of an email you have to triage. Name a subreddit to watch that community, or send a keyword with no subreddit at all and it watches every new post on Reddit:
curl "https://api.redditapis.com/api/monitor/add" \
-H "Authorization: Bearer YOUR_API_KEY" \
-d '{"q":"your brand"}' # no subreddit: all of RedditAdd "subreddit":"SaaS" to scope that same monitor to one community instead. Full endpoint paths and parameters live in the API docs. See the full monitoring product on the Reddit monitoring API page.

F5Bot is a keyword-alert bot that watches Reddit, Hacker News, and Lobsters and emails you when your terms appear. Its tier matrix lists five plans: Free for 5 keywords, Silver $9.99 for 20, Gold $49.99 for 200 with RSS, JSON, Slack and Discord, Platinum $214.99 for 300 with the API and webhooks, and Diamond from $500.
For Reddit specifically, a Reddit-native monitor like Redditapis. It watches named subreddits or all of Reddit with author, score, and keyword filters, and pushes matches to a webhook, Slack, or Discord on every paid tier from $19 a month, where F5Bot puts Slack and Discord on $49.99 Gold and webhooks on $214.99 Platinum.
Yes, since August 2026. Leave the subreddit field empty, type a keyword, and the monitor matches every new post anywhere on Reddit. The count is capped per plan: 1 sitewide watch on Starter, 3 on Growth, 10 on Pro, and 25 on Scale. Each one also uses an ordinary monitor slot, and sitewide watches cover posts, not comments.
Use F5Bot when you want one bot watching Reddit, Hacker News, and Lobsters together, email alerts are enough, and you track many terms sitewide, since it meters keywords rather than watches. Use Redditapis when Reddit is the job: Slack, Discord, or webhook delivery without paying for a top tier, per-subreddit and per-author filters, and a full Reddit data API underneath.
Yes, from its Gold tier at $49.99 a month, which carries one integration; Platinum at $214.99 carries three. F5Bot's free and Silver ($9.99/mo) tiers deliver by email only, and webhooks are Platinum and above. Redditapis includes webhook, Slack, and Discord delivery on its cheapest paid tier at $19 a month.
Five tiers. Free for 5 keywords, Silver $9.99 a month for 20, Gold $49.99 for 200 with RSS, JSON, Slack and Discord, Platinum $214.99 for 300 which is where the API and webhooks start, and Diamond from $500. Annual billing is $109, $549 and $2,364. The matrix is published at f5bot.com/tiers.
Yes, with Redditapis. Monitoring sits on top of the same 52-endpoint Reddit REST API used for search, comment search, user and community lookups, and write actions, so the same account that watches keywords can also pull historical data, reply, vote, or DM over the same authenticated API.
F5Bot's free tier publishes a limit of 5 keywords with alerts within 2 hours, capped at 10 alerts per keyword a day and 20 across the account, email only, and it rejects very common words. Teams that outgrow 5 terms, need alerts in minutes rather than hours, or want the match routed to Slack, Discord, or a webhook move to a paid plan.
