Why people look beyond ReddRadar.

ReddRadar is a Reddit lead tool for founders and marketers. You describe your product once; it watches 500+ top subreddits, alerts you by email or Slack when a relevant post appears, weighs the lead's intent and sentiment, and prepares a reply before, in its words, your competitors notice. 1

It sells one plan at $19 a month, with a 7-day free trial and no credit card. The plan includes one project, email and Slack alerts, sentiment analysis and comment generation, and an Auto Responder that can send replies automatically or hold them for your approval. 1

Upthread leaves the sending to you and starts from search. It finds the threads Google and AI answers show your buyers, in any subreddit, drafts replies with your disclosure inside each subreddit's rules, and records what each reply did after you post it.

Price and plans

Upthread$49 / $149 / $499 a month, or 2 months free yearly. A 7-day trial with Starter limits. No card required.

Switching from ReddRadar.

You describe your product to Upthread by giving it your website address; it drafts the brand profile and suggests competitors, keywords, 15 to 25 buyer questions and focus subreddits. Review them, set your role and disclosure line, pick engines and a country, and the first runs start, aiming at a ranked inbox in under three minutes. The extension is the optional last step.

What you bring across

  • Your product description. Upthread drafts a fuller brand profile from your website, and you edit it before the first run.
  • Your Slack alerts, on Upthread's Growth or Agency plan, for new high-priority threads and for changes in citations.
  • The kinds of posts you treat as leads, written as buyer questions and keywords, so Upthread can look for them in Google results and AI answers.

What works differently

  • ReddRadar's Auto Responder can send replies automatically. Upthread has no sending mode at all: you read the draft, the extension inserts it, and you click Comment from your own account. 1
  • ReddRadar watches a set of 500+ top subreddits. Upthread follows Google results and AI citations into any subreddit, and ranks each thread by Google rank, citations per engine, buying intent, freshness and how the subreddit treats brands. 1
  • ReddRadar says a good reply can end up cited by AI tools. Upthread checks it: it asks your buyer questions in Google AI Overviews, AI Mode, ChatGPT, Perplexity, Gemini and Claude and records the Reddit threads each one cites. 1
  • After you post, Upthread records the reply's score over time, any moderator removal and the thread's citation history, and on Growth and Agency plans it can share that record as a read-only report.

How Reddit access is changing

Reddit is closing its public API and moving toward logged-in viewing. This matters for any tool that reads Reddit, so each comparison states only what the tool itself says about its data source.

  1. On Oct 29, 2026, Reddit said it will shift to a primarily logged-in experience, starting with tests in select markets outside the US. 3
  2. 9to5Mac reported that Reddit will start requiring a logged-in account for most of its content. 4
  3. Reddit's CEO said most unauthorized access to its content happens through the logged-out experience. 5

ReddRadar and Upthread: questions.

Does ReddRadar post replies automatically?

It can. Its FAQ says you can configure the Auto Responder to send replies automatically, or hold them for review and approve each in one click. Upthread never posts: a reply goes out only when you click Comment. 1

Which subreddits does ReddRadar cover?

It monitors 500+ top subreddits and says the list is growing. Upthread isn't limited to a list: it finds threads wherever Google results and AI answers point, including small subreddits. 1

Which one costs less?

ReddRadar, at $19 a month for its one plan. Upthread Starter is $49 a month, and the difference buys AI answer tracking, drafts checked against each subreddit's rules with your disclosure, and reply records. 1

Where does ReddRadar get its Reddit data?

Its homepage doesn't say. Upthread gets threads from Google results and AI citations, reads their text in your own logged-in browser or from a paste, and calls no Reddit API. 1

Can I use ReddRadar and Upthread together?

Yes. New-post alerts from popular subreddits and Upthread's inbox of cited threads answer different questions, and the replies you post from Upthread keep their own record.
