Outgrown F5Bot's email alerts? Prowlo is the agent-first next step.
F5Bot is the best free keyword-alert tool out there — and its Ultra tier even adds an API and Slack/Discord webhooks. But every F5Bot alert is a window onto “right now.” Prowlo is a memory: every match is indexed into a persistent, semantically-searchable Dataset your agent queries over MCP — with X alongside Reddit and Hacker News. Free 14-day trial, then $19/mo flat.

Animated demo: an AI agent scans hundreds of Reddit and X posts through Prowlo, keeps the few high-intent ones, runs a draft in a sandbox, and sends a Slack digest.

Prowlo vs. F5Bot
F5Bot is a well-regarded keyword-alert service for Reddit, Hacker News, and Lobste.rs — free for 200 keywords, with paid Power and Ultra tiers that add an API and webhooks. Prowlo is a different shape: a persistent, semantically-searchable Dataset your agent queries directly over MCP — a memory, not a live alert window.
Comparison reflects publicly documented F5Bot functionality as of June 2026. F5Bot Free covers 200 keywords; Power (~$17/mo) and Ultra (~$70/mo) raise limits and add an API plus Slack/Discord webhooks. F5Bot is the best free keyword-alert option — Prowlo is for teams that want a persistent, agent-queryable Dataset instead of a stream of alerts.
F5Bot alerts you to a moment. Prowlo gives your agent a memory.
MCP server your agent calls
F5Bot has no MCP server — its Ultra API is a REST feed you poll yourself. Prowlo was built for the agent era. Install the MCP server in Claude, Cursor, or Cline and your agent gets search_dataset, social_search, and list_watchers returning clean typed JSON. No polling, no parsing.
Search your history, not the latest alert
Every F5Bot alert — email or Ultra webhook — is a window onto matches that just landed; once it scrolls past, it is gone. Prowlo indexes every match into a persistent Dataset you can search semantically ("posts about frustration with onboarding, last 30 days") at any time, in any order, weeks later.
One schema across three sources
F5Bot covers Reddit, Hacker News, and Lobste.rs. Prowlo adds X (Twitter) and Mastodon and normalizes every source onto one record schema — so a single semantic query spans Reddit and X together, and your agent never juggles per-platform formats.
“We previously used a tool that only let us monitor a small, manually-defined list of subreddits (around 10 max). That approach was too narrow. Prowlo changed the game by tracking a wide range and surfacing only the relevant ones for our 3D furniture rendering service. We landed 4 new customers in our first month and a half that we'd never have found otherwise.”

Moving from F5Bot
F5Bot has a free tier — why pay for Prowlo?
F5Bot's Free tier (200 keywords, email) is the best free keyword-alert option out there, and its paid Power (~$17/mo) and Ultra (~$70/mo) tiers add an API and Slack/Discord webhooks. But every F5Bot delivery is an alert — a window onto matches that just landed. Prowlo is a different shape: it indexes every match into a persistent, semantically-searchable Dataset your agent queries over MCP. You're paying for a memory of your niche, not just a faster stream of alerts.
Does Prowlo monitor Hacker News like F5Bot does?
Yes. F5Bot covers Reddit, Hacker News, and Lobste.rs; Prowlo covers Reddit, X (Twitter), Hacker News, Mastodon, and RSS. Point a Watcher at Hacker News and it gets indexed into your Dataset alongside Reddit and X. F5Bot is still the best free option if simple HN keyword alerts are all you need.
How does the MCP integration work?
Connect the Prowlo MCP server in Claude, Cursor, or Cline with one URL. Your agent gets tools like search_dataset, social_search, and list_watchers — all returning clean typed JSON. Your free 14-day trial includes full MCP access.
How much does Prowlo cost?
Free 14-day trial with full access — no card required. After that, one flat plan at $19/mo for 25 Watchers across subreddits, Reddit users, Hacker News, Mastodon, RSS & X. No per-mention charges, no API fees.
Can I import my F5Bot keywords?
Yes. Drop your keywords and subreddits into a Watcher during setup — same names, no lock-in. Prowlo starts indexing them immediately. The overlap with F5Bot's monitored sources is substantial.
Does F5Bot limit how many alerts I get?
On F5Bot's Free tier, a keyword auto-disables after 50 hits in 24 hours (paid tiers raise this to 1,000/day) — it's a per-keyword anti-spam threshold, not a flat account cap. Prowlo meters daily record caps silently and keeps every match: instead of a capped alert stream, you get a persistent Dataset you can search semantically across the full history whenever you — or your agent — need it.
Other Reddit + X monitoring alternatives we compare to
F5Bot isn't the only tool people move from. Prowlo is also a common next step for GummySearch users who lost access after its shutdown, Syften users who hit filter caps, and Apify users tired of compute-unit billing. Comparing every alert method first? See five ways to set up Reddit keyword alerts.
You are here
F5Bot alternative
Email-only alerts vs. MCP + API + Webhook + semantic search. Prowlo is the agent-first upgrade from F5Bot.
GummySearch
GummySearch alternative
GummySearch shut down in 2025. Prowlo is the agent-first replacement — Reddit + X, MCP-native, free 14-day trial.
Syften
Syften alternative
Syften pioneered indie keyword monitoring and now ships an MCP server too. Prowlo offers the same coverage with no filter-count caps and a persistent Dataset, not just a live feed.
