Social Media Search Engines in 2026: What You Can Actually Search

I set out to compare the search engines people use to find what is being said about them, and I got stopped twice before I had finished taking the screenshots for this post.

X returned "Access to x.com was denied". Reddit showed me a CAPTCHA that said "Prove your humanity". Neither of those is a complaint. They are the answer to the question the whole category dances around: what are these search engines actually allowed to search?

So I read the instructions each platform publishes to the world's crawlers, and then I sat with ten tools and searched the same brand in each of them.

Some of what gets sold as a social media search engine is very good. Some of it is a set of links to other people's search boxes. One of the best things here is free, has no marketing, and most marketers have never opened it.

Ours is in the list too, first, and it is the one that is not a search engine at all. I will explain why it is here and what it cannot do.

Everything was read from each tool and each platform's own files on 1 October 2026.

The ten, side by side

Click a tool to jump to its section.

Tool	What it searches	Price	The catch
BrandRobin	17 named channels, continuously	Free 7-day trial, paid plans unpriced	Not a search box; it monitors instead
Google	Whatever each platform permits	Free	Blind wherever robots.txt says so
Google Alerts	Web and news, as they appear	Free	Barely touches social
Social Searcher	Several networks, one box	Free tier, paid plans	Depth varies by network
Boardreader	Forums and message boards	Free	A narrow slice of the web
Hacker News Search	All of Hacker News	Free, API included	One community only
Bluesky	Bluesky posts, with operators	Free	Pushes you to sign in
X advanced search	X, with the best operator set	Free with an account	Nothing without logging in
Reddit search	Reddit, natively	Free	Worse at Reddit than Google is
Brand24	A paid index across channels	From $199/mo billed annually	A subscription, not a search box

What the platforms tell search engines, in writing

Before the tools, the constraint they all share. A robots.txt file is a platform's public instruction to every crawler on the internet, and it is the least ambiguous thing any of these companies says about who may read them at scale.

Platform	What its robots.txt says	What that means when you search
Reddit	User-agent: * — Disallow: /	No crawler is permitted. Google shows Reddit under an agreement, not an open door
X	Googlebot and Bingbot get a short allow-list; /search/realtime and /search/users are disallowed	Search pages are off-limits to indexers, and logged-out search shows a wall
LinkedIn	Googlebot is disallowed from /feed/update/	That is the address of every post, so posts are not in the index
Instagram	Amazonbot, ClaudeBot, GPTBot, PerplexityBot, Google-Extended: Disallow: /	No public keyword search worth the name
Threads	Automated collection 'prohibited unless you have express written permission'	The same posture, in plainer English
YouTube	Disallow: /comment, among others	Videos are searchable. The comments underneath them are not
Bluesky	Allow: /	The only large network whose file says yes
Hacker News	Open, with Crawl-delay: 30	Fully searchable, and it shows

Read the right-hand column from top to bottom and the category rearranges itself. The two platforms nobody markets at you are the two you can actually search. The ones every tool advertises are the ones nobody is allowed to index.

How I compared them

Five things, and they decided every pro and con below.

• What it is actually permitted to see. Not the number of networks on the homepage. The ones its own supply allows it to return, which is a different and much shorter list.
• Whether it works without an account. A search engine you have to log in to is a feature of a platform, not a search engine. I checked each one cold, in a clean browser.
• The operators. Date bounds, author, engagement thresholds, exclusions. Operators are the difference between a search and a scroll, and the good free tools have better ones than most paid dashboards expose.
• Whether anything is kept. A search box shows you now. Something that keeps a record can show you the month you were not looking, and almost nothing free does.
• What happens when you are not at the keyboard. The mention that costs money arrives on a Saturday. Search cannot help with that by definition.

Three different things get sold as a social media search engine

Redirectors. You type once, they open eight native searches in eight tabs. Nothing is unified and nothing is stored, which is why they are free.

Aggregators with their own supply. They keep an index, which means they obtained the content somewhere: an API they pay for, an agreement, or a scraper. Quality and legality both follow from which one, and it is the question nobody asks.

The general web index. Google and Bing with site: operators. Free, enormous, already built, and limited to whatever each platform permits.

A fourth group keeps being sold as the other three: the platforms' own search boxes. They are the primary source, they are free, and on two platforms they are better than anything built on top of them.

BrandRobin

brandrobin.ai

Ours, and first because it is ours. It is also the only thing on this page that does not belong in a list of search engines, which is worth saying before the pros.

The catch: if what you want is to check a competitor's name once this afternoon, close this tab and use the free stack below. It will serve you better and cost nothing. We are the answer to a different question, which is what happened last month while nobody was searching.

Google

google.com

The catch: it is the best free social search engine, and it is not a social search engine. You are searching Google's copy of whatever leaked out, which on some platforms is most of it and on others is nothing.

Google Alerts

google.com/alerts

The catch: set it up anyway, today, because free alerting on your own name is strictly better than nothing. Just do not mistake a quiet inbox for a quiet month.

Social Searcher

social-searcher.com

The catch: worth a bookmark for a quick sweep. Judge it by which networks it returns anything useful on for your particular brand, not by the number of logos on its homepage.

Boardreader

boardreader.com

The catch: nobody should buy anything on the strength of Boardreader, but if your market argues on specialist forums it will find threads that no social tool on this page will.

Hacker News Search

hn.algolia.com

The catch: this is the best free tool on the page by some distance, and the one almost nobody opens. If you sell software, search your own name and your competitors' in the comments, not the stories. That is where the opinions are.

Bluesky

bsky.app

The catch: the policy is the most open of any large network and the practice was less so on the day I tested it. Make an account, use the operators, and do not assume the API will be there if you build on it.

X advanced search

The catch: the best operators here belong to the platform that has done the most to make sure nothing else can read it. Use it directly, with an account, and do not expect any tool to reproduce it faithfully.

Reddit search

The catch: use Reddit's own search when you know the subreddit, and Google with site:reddit.com when you do not. That single habit will improve your Reddit research more than any tool purchase.

Brand24

brand24.com

The catch: included here as the shape of the paid end rather than as a recommendation over its rivals. If you want that comparison properly, the best social listening tools post does it across ten of them.

What no search box does, at any price

Everything above answers one question: is anyone talking about this right now. Four things none of them do.

They cannot tell you when. Search is a thing you remember to do. The thread that costs you money arrives on a Saturday and search finds it after somebody else has already told you.

They cannot keep a record. Posts get deleted, threads get locked, and a search run today cannot show you last quarter. If nothing was capturing it at the time, that month is gone.

They cannot find what you did not think to type. You search your brand. You do not search the misspelling, the competitor comparison that never names you, or "anyone know a tool that does X", which is the most valuable sentence on the internet for you.

They cannot dedupe or rank. Ten results from one syndicated story look like ten mentions; one Reddit thread with 400 comments looks like one result. Volume read off a search page is the least reliable number in this field, which is why mention counts lie.

Which one I would open first, by situation

If you are…	Open this	Why
Past the point of remembering to search	BrandRobin	It watches and backfills; there is nothing to remember
Checking a name once this afternoon	Google, with site:	Free, instant, and better than most paid search boxes
Selling to developers or founders	Hacker News Search	Free, fast, open, and the comment search is where the opinions are
Wanting a free tripwire and nothing more	Google Alerts	Two minutes, and it tells you without being asked
Looking across several networks at once	Social Searcher	One box, no account, good enough for a sweep
Selling into a forum-shaped market	Boardreader	The forum layer nothing else indexes
Investigating one thread in depth	X advanced search, Reddit search	The operators only the platform itself gives you
Ready to pay for alerting and history	Brand24	A published price and the things free search cannot do

The ten-minute sweep

If you take nothing else from this comparison, take this. It costs nothing.

1. 01

   Google first, with site:

   site:reddit.com "your brand", then the same for news.ycombinator.com and any forum your market lives on. This will outperform most of the purpose-built tools on this page.

2. 02

   Hacker News comments, if you sell software

   Search your name and your two closest competitors at hn.algolia.com, and filter to comments rather than stories. Stories are announcements; comments are opinions.

3. 03

   X with an account, using thresholds

   min_replies:5 on your brand name finds the complaints that got a conversation going, and skips the ones nobody saw. Add since: and until: to bound it to the week you care about.

4. 04

   Set one Google Alert before you close the tabs

   It takes two minutes and it is the only part of this sweep that keeps working after you walk away. It will not catch much social, and it is still better than relying on memory.

What this comes down to

There is no search engine for social media, because the platforms have spent three years making sure there cannot be one. What exists instead is a patchwork: two genuinely open communities with excellent free search, one general web index working from whatever it is permitted to keep, a handful of aggregators whose quality depends entirely on how they got their data, and a set of login walls.

So the question is not which social media search engine is best. It is whether the job in front of you is search at all. If you want to know what is being said right now, the free stack above is as good as anything sold, and I would not spend a dollar on this category until it stops answering. If you want to know what was said while you were not looking, see how social listening works instead. That is a different verb, and it needs a different tool.
