A Stalkr alternative, compared honestly
Stalkr and Nephia are built for the same founder: track your brand, your product and your competitors, catch the bug reports and the testimonials, and hand the mentions to an agent through an API, webhooks and MCP.
Stalkr reads X, Reddit, YouTube and LinkedIn and counts mentions against a monthly cap; Nephia reads 14 sources but not LinkedIn, counts no mentions, and starts at $19 a month.
The table below puts the two side by side, with the date and page every Stalkr figure was read from.

What Stalkr does better
- Stalkr reads LinkedIn on every plan; Nephia does not read it. If your buyers post there, that settles it.
- Team members
- Its Pro and Scale plans let a team share one account. Nephia accounts have one member.
Where Nephia is different
- No mention cap
- Stalkr pauses the feed when a plan’s mentions run out. A Nephia plan sets how many queries run and how often; a launch week that brings ten times the mentions costs the same.
- 14 sources
- Hacker News, Bluesky, TikTok, GitHub, Product Hunt, Stack Overflow, Mastodon, Lemmy and any RSS feed besides X, Reddit and YouTube, plus ChatGPT, Gemini and Perplexity as a source.
- A reply drafted, and a spike alert
- Each mention worth an answer comes with a draft in your tone, and every Query ships with an alert for the day that catches about three times its usual volume.
- A public page of your mentions
- Stalkr has one too. A Query can publish its mentions on a public page, opt-in, read-only, and kept out of search engines unless you list it.
Questions
Is Nephia cheaper than Stalkr?
Solo is $19 a month at launch, and free during the public beta, against $29 a month for Stalkr Starter as published on 2026-09-15. Stalkr Starter counts 1,000 mentions a month; no Nephia plan counts mentions at all.
Does Nephia monitor LinkedIn like Stalkr?
No, not today. If LinkedIn is where your buyers post, Stalkr covers it and Nephia does not.
Can an AI agent read Nephia’s mentions the way it reads Stalkr’s?
Yes. The MCP server connects ChatGPT, Claude or Cursor with an OAuth sign-in and no key, and the REST API and signed webhooks are on every plan, Free included.
