At a glance
- No X API key, ever. Prowlo sources its data independently, so X’s February 2026 free-tier shutdown never interrupted a Watcher. Building the same thing on X’s Basic API tier starts at $200/mo before you write a line of code.
- Hourly alerts, not daily digests. Fast enough to reply while the thread is live; slow enough that Slack stays readable.
- X and Reddit in one plan — 25 Watchers across subreddits, Reddit users, Hacker News, Mastodon, RSS & X. A thread that starts on X and continues on r/SaaS lands in one Dataset under one schema.
- Semantic matching, not just exact strings. “anyone else fed up with their listening tool” surfaces for a monitoring product even though it contains none of your keywords.
- Read-only by design. Prowlo finds and ranks; a human posts. No auto-replies, no DMs, nothing that gets an X account flagged.
- $19/mo flat, 14-day free trial, no card — see pricing.
Shopping around first? The 11 X monitoring tools compared by price covers the whole market, free tiers included — Prowlo is one row in that table.
Why X monitoring got expensive
Every X monitoring tool needs X data, and since the free API tier closed in February 2026 there are only two ways to get it: pay X’s rates, or build an independent pipeline. That single fact sets the price of everything else on the market.
A column is not an alert
X Pro gives you saved-search columns for $8/mo with X Premium, and they work exactly as well as you remember to look at them. Native notifications only cover replies, handle mentions, and accounts you follow — never a keyword.
One platform answers half the question
For SaaS and devtools, a comparison starts on X and the “which one did you pick?” follow-up lives on Reddit. Tools that treat X as a standalone product sell you half a conversation, then charge separately for the other half.
Exact-match alerts miss the buyers
The posts worth finding rarely contain your keywords. Someone describing the problem you solve, in their own words, is invisible to string matching — and that is the post you actually wanted.
How X monitoring works in Prowlo
One Watcher, four steps, about two minutes of setup.
Create a Watcher
Pick the X accounts and keywords worth watching — your brand, three competitors, and the category phrases your buyers use. Each Watcher tracks one channel.
Prowlo checks hourly
New matching posts land in your Dataset every hour, filtered by the intake rules you set: minimum engagement, language, post age, known promo accounts excluded.
Every match is embedded
Records are vector-indexed on arrival, so your agent can search by meaning rather than spelling — including posts that describe your category without naming it.
Results reach you four ways
Slack, webhook, REST, or MCP. Same record schema across all of them. Your agent reads and drafts; you decide what gets posted.
What X monitoring costs elsewhere
Starting prices from public pricing pages, checked 1 September 2026. Most tiers meter by tracked terms, so the advertised price is rarely the price at scale.
| Tool | Starts at | Covers |
|---|---|---|
| X API (Basic tier) | $200/mo | Build it yourself |
| X Pro (TweetDeck) | $8/mo | Columns, no alerts |
| CommunityTracker | Free; $39/mo | 1 keyword free, daily email |
| Prowlo | $19/mo flat | X + Reddit, hourly, MCP |
| SnitchFeed | $47/mo annual | 5 platforms, 10 terms |
| Brand24 | $79/mo | X + 5 platforms, PR reports |
| Octolens | $159/mo | Multi-platform, AI listening |
Prowlo is our product, so read that row with the appropriate suspicion — and note where it loses. If you only need to know when your own brand name comes up, CommunityTracker’s free tier does that for nothing. If you need sentiment charts for a stakeholder deck, buy Brand24. Prowlo is the right answer when the data feeds an agent or a workflow, and when X alone was never the whole picture. The full comparison of 11 tools goes through each one.

Pick a tool that sources X data independently — X's own API starts at $200/mo for the Basic tier, which prices out most keyword monitoring. In Prowlo: create a Watcher on the X accounts and keywords you care about, connect Slack or a webhook, and matches arrive hourly. No X developer key, no per-read metering.
No. X's native notifications cover replies, mentions of your handle, and accounts you follow. X Pro (formerly TweetDeck, included with X Premium at $8/mo) gives you saved-search columns, but a column is something you look at — it never pings you. Every real X keyword alert runs through an external tool.
Yes. X search supports from:username keyword for one account's posts and to:username for replies. That handles one-off lookups. Prowlo turns the same idea into a standing Watcher: put the account on watch, and every new matching post lands in your Dataset and your Slack channel.
Hourly. That is fast enough to reply while an X thread is still live, and slow enough that Slack stays readable. Daily digests miss the window where joining a conversation still counts; real-time firehoses get muted by week two.
No. Prowlo sources its data independently, so you never register an X developer app, never hold a key, and never see X's per-read pricing. That is also why X's February 2026 free-tier shutdown did not interrupt Prowlo Watchers.
Both, in the same plan and the same Dataset. $19/mo covers 25 Watchers across subreddits, Reddit users, Hacker News, Mastodon, RSS & X. A comparison thread that starts on X and continues on r/SaaS shows up as two records under one schema — no second subscription, no second dashboard.
No, and it never will. Prowlo is read-only by design: it finds, ranks, and hands your agent typed JSON, then a human posts. Automated engagement is how X accounts get flagged, so we do not build it.
Yes. Prowlo is an MCP server, so Claude, Cursor, or any MCP client can call search_dataset against your watched X accounts and keywords and get back typed JSON ranked by semantic relevance. REST and webhooks cover everything that is not an agent.
