Best SaaS Idea Finder Tools (2026): Compared by Source

As of October 4, 2026, there are a few tools to help find SaaS ideas. Their prices range from free to $2,999/year for IdeaBrowser (the least expensive of its plans is $499/year). Those ideas, by the way, come with scores that their pages call "educational and based on assumptions." One tool, Starter Story, lists 3,067+ money-making projects, for free.

Disclosure: Preuve AI, my startup demand-checking tool, benefits from idea finders: you’ll need to check the ideas they give you. I also built one of the free generators below. On this page, I share what the different tools charge (based on their own pages, October 4, 2026) and what Reddit threads say (links below).

Which SaaS idea finder tools cost what, and where do their ideas come from?

I compare 6 tools, and a bunch of AI idea generators. SaaS here means software accessible by subscribing to it. The prices are based on what their own pages say, October 4, 2026. Prices are in US dollars.

Tool	Where the ideas come from	Price	Free option	The catch
IdeaBrowser	Written and scored by IdeaBrowser	$499, $1,499 or $2,999 a year	Idea of the Day	Billed annually by default; scores are "educational"
BigIdeasDB	Complaints from G2, Capterra, Upwork and the app stores	$99, $199 or $349 one-time, or monthly	Tools and calculators	20 searches a day below Pro; export is Pro only
Exploding Topics	Search and social growth, checked by its team	$39, $99 or $249 a month, billed yearly	Trend library, no login	A trend is attention, not a paid problem
PainOnSocial	Reddit posts in subreddits you pick	$19 or $49 a month	1-week trial, live demo	Reddit only
Starter Story	Breakdowns of projects that already earn	Free	Yes, behind an email form	Someone already runs each idea
Indie Hackers	Founder stories with self-reported revenue	Free	Yes	Revenue is what the founder says
Generators	A language model, from what you type (TurboStarter, Preuve AI, a Chrome extension)	Free (one extension needs your own OpenAI key)	Yes	No demand data behind the ideas

Where do SaaS idea finders get their ideas?

SaaS idea finders are tools for finding SaaS product ideas. They each get those ideas from 1 main type of source.

A would-be SaaS founder, writing on r/SaaS in September 2026, after months of searching for ideas, said:

"I look at Reddit, businesses, existing software, different industries, etc. and either the problem isn't painful enough, there are already tons of solutions, or I can't see why someone would actually pay for it." (r/SaaS, September 2026)

The tools below can get you past at most 1 of those 3 problems, depending on what their sources of ideas are. Their sources can be databases of complaints, trend-finding tools, databases of revenue-generating businesses, Reddit posts, or LLMs.

About AI idea generators, one of the comments in the following thread from r/SaaS, AI is bad at SaaS ideas (read October 4, 2026), says "Claude has the same training data as everyone else asking it the same questions, so of course it's gonna spit out ideas that already exist or sound good but have no buyer." That is one comment, so no test was done. Still, I built an idea generator myself, and its page says "does not prove demand on its own."

What does IdeaBrowser give you, and is it worth it?

You pay for finished ideas, written up and scored. Its pricing page (read October 4, 2026) lists three plans, all yearly:

Source: IdeaBrowser pricing page, read October 4, 2026. All three plans are billed yearly.

How many ideas? The plans table says "1,000+". But the database section of the same page says "800+ fully-researched startup opportunities." I'd say about a thousand. The free way in is their Idea of the Day. One page, one idea, every day.

The scores carry a label from their own pages: "Analysis, scores, and revenue estimates are educational and based on assumptions." One idea I read for free scored 9/10 for opportunity and 9/10 for problem. In an r/SaaS thread from a year ago, a user who checked their daily ideas found that "some of them don't make any sense", with a warning about paid idea platforms in general. On r/indiehackers, a user said they skip the Pro plan and paste the ideas into Claude Code.

My take: if you're not going to work on those ideas every week, don't pay $499 for them. Reading one a day is free, with the Idea of the Day. I wrote a full comparison of IdeaBrowser on another page. A list of IdeaBrowser alternatives is on yet another page.

What does BigIdeasDB find, and what does it cost?

BigIdeasDB is a database of complaints. From their pricing page, as of October 4, 2026, their data comes from G2, Upwork, Capterra, the App Store and Google Play. It also lists "curated problems and solutions." The vendor says it has "1M+ validated user complaints and 15,000+ SaaS ideas." There are 3 plans, sold outright. There’s also a monthly plan, and the page’s own title advertises it from $29 a month.

Source: BigIdeasDB pricing page, read October 4, 2026.

The main thing I like here is that the limitations between plans are specific. On October 4, Pro showed $599 with a strikethrough and a counter next to it: "80 spots left at $349." Still, I wouldn’t be tempted to spend that much ($349) when the starting point for Lite is only $99 and it has the same core data sources. And if you want to see if their tools and calculators (and idea generator) work for you before spending anything, you can read about the free version on the BigIdeasDB Plans page.

Their sales are final, unless you’re part of their Build Challenge, where if you find a product to build in their database and actually launch it, they’ll give you 25% of your purchase back; if you get to $1k in revenue, you get 50%; if you get to $10k, you get your full purchase price back. It’s a small thing but nice. An independent review, MakerStack’s 7.1/10 from June 19, 2026, says "the data can feel stale and pricing varies across listings."

So if you want to read raw complaints yourself and you don’t like subscriptions, this is the plan for you, $99. But if you want a thorough review of what the product and people are like, check out my BigIdeasDB review.

Can Exploding Topics find SaaS ideas?

Exploding Topics finds things that are getting more attention on search and social media. From the site, they analyze "consumer behavior signals across dozens of platforms" and identify emerging trends with an algorithm. Then "we manually analyze the data, confirm and curate trends." From their pricing page (read October 4, 2026), they claim a database of "1.1M+" trends and list three plans:

The Entrepreneur plan, at $39/month, lets you track 100 trends and run 10 analyses. The Investor plan, at $99/month, lets you track 500 trends and also gives you trending startups, forecasts, and the ability to export data to a spreadsheet. The Business plan, at $249/month, lets you track 2,000 trends and also shows you trend reports.

This is their comparison between the free plan and the paid plans, updated March 23, 2026. Their prices here are for yearly billing, and it looks like you can browse the trend library for free without even logging in, so check it out! Exploding Topics is a trademark of Semrush, by the way, according to their site footer.

In this case, it’s up to you to decide if the trends they’re showing are something you want to solve. They’re things people are interested in, not necessarily things people are paying money for to fix. Start with the free version and see if, after a few months, the paid versions are worth it for your particular market.

Can PainOnSocial find SaaS ideas from Reddit?

They scan the last 7, 30, or 90 days of the subreddits you pick, then show you the pain points ranked, with the posts as evidence, then ideas for what you could do about those pain points. From the PainOnSocial pricing page (read October 4, 2026), they have two plans:

Source: PainOnSocial pricing page, read October 4, 2026.

There is a demo on their pricing page: you pick a subreddit and see what you get, without signing up. The vendor says it is "Trusted by 4,000+ Founders."

Their pitch: browse Reddit for this yourself and it will take about 20 hours a week. At $50/hour, that is $4,000/month, against the $19 they charge. That is the vendor's math, not a measured result. A founder on r/SaaS, who spent weeks gathering this data by hand, put the risk of the whole category in one line:

"Most 'pain point research' tools give you 100 random complaints." (r/SaaS, March 2026)

The quote targets pain point tools in general, but it may apply here too. PainOnSocial tries to fight it by ranking the pain points and showing the posts. 20 scans of 2 subreddits a month can be enough, or not. It depends on how narrow your market is. So take the free trial, run it on the subreddits your market actually sits in, and see if a week is enough to answer that. If not, cancel and move on.

What happened to GummySearch, and what replaced it?

GummySearch, a tool for researching your audience on Reddit, closed on November 30, 2025. From their closing page, they closed because "we're shutting down to comply with Reddit's API policies, which forbid commercial applications." The page says over 140,000 founders, marketers and investors relied on it. They’re no longer taking new signups, but if you bought a lifetime deal, you can keep using it until November 30, 2026. They also said they plan more market research products in 2026.

My read: if you’re depending on a tool that only sources from one platform, you’re at the mercy of that platform’s rules, as was GummySearch, and as PainOnSocial and the Chrome extension below are.

The free one comes last. The Reddit link comes from this r/SaaS post from July 2026. In the post, one reply says "Tools are rented; the taxonomy you build from the research is the asset." Another, from a commenter who then plugged their own tool, gives the free method: set up a saved search with the five keywords you want to monitor. Then, every couple of days, you visit that search and record the conversations in a spreadsheet, including the problem and the link to the Reddit conversation.

Where can you find SaaS ideas that already make money?

Two free databases of successful startups that you can study for ideas are Starter Story and Indie Hackers. These are different than the other methods on this list because, instead of starting with a problem, they start with a business. The Starter Story database is on their homepage (as of Oct. 4, 2026). "Search 3,067+ real, revenue-generating projects" for free. You can filter by any of 39 databases, including Micro SaaS Ideas (704 ideas, median $40K/month), Problems (1,067 problems), and more. The email form says HubSpot gets your address and shares it with Starter Story.

Indie Hackers calls their ideas database "A database of reports on successful startup ideas, tailored for indie hackers." Their database is free, and the income figures come from the founders themselves.

The problem with both of these databases is that the ideas already belong to somebody. To find an angle, you need to figure out how to outcompete the original business. Also, the databases are biased toward successful startups, so the $40K median is not representative of the average idea. However, if you want a free tool to find ideas that already earn money, these are a good first stop.

Are free SaaS idea generators any good?

Two free generators and one extension. The Preuve generator is mine, so read that row with that in mind.

Source: the TurboStarter ideas page and the Preuve free tools page, read October 4, 2026; the Chrome Web Store listing, as of September 2026.

If you don’t have any SaaS ideas, you can try plugging your info into a generator like the ones above.

Which SaaS idea finder should you use?

I suggest using the finder that helps you find the kind of ideas you’re looking for. Here’s a quick guide (prices are from reading the websites above on Oct. 4, 2026):

Source: the vendor pages covered above, prices read October 4, 2026. The pick column is my reading.

Where does Preuve fit, and where does it lose?

By the way, Preuve is not a SaaS idea finder. Preuve doesn’t have a list of ideas, a list of complaints, a list of new ideas, or a way to scan Reddit for ideas, and it doesn’t email you ideas each day. Except for the generator above, Preuve doesn’t give you ideas. If you need ideas, the tools above will help you more than Preuve will.

Use Preuve one step later on your 1-3 favorite ideas to validate whether someone might buy it. When you have a few ideas, scan them yourself and let Preuve scan 60+ data sources with 10 parallel AI agents to check whether there is enough demand in the market for your idea. The free Reality Check takes under a minute.

One downside is that Preuve only gives you a score as good as the idea you type in (garbage in, garbage out). From benchmarking Preuve on 6,000+ idea analyses, the biggest risk is that your idea might be too early to score (36.9% of tagged analyses). You also still need to talk to potential buyers to validate your ideas. For a comparison of startup idea validation tools, see my comparison of startup validation tools, and for a list, the free idea validation tools.

What does a found idea still need before you build?

What if you want to validate an idea you found? If you find an idea you like, there are a few things you want to check before you start building: Is there a market of people who are willing to pay for your idea? How big is that market? How do they pay for this now? Who are your competitors? Unfortunately, none of the entry plans in this comparison can run those checks for you. IdeaBrowser says it can (with their research agent), but that starts with their $1,499 Pro plan.

On October 4, 2026, IdeaBrowser’s free Idea of the Day was "Viral ad licensing for direct to consumer brands", a tool called Cliprights.

Source: IdeaBrowser Idea of the Day, read October 4, 2026. Scores are IdeaBrowser's own, out of 10; the keyword figures are the ones the card shows, without a stated time window. The "Still open" column is my reading of the card.

The card itself says that whether a post converts as a paid ad "stays open until a deal closes," and the card hands it back to you.

Why check demand before paying for a finder?

Money isn't the whole problem, even though you may pay every year for an idea finder (prices as of October 4, 2026):

Source: IdeaBrowser, Exploding Topics, PainOnSocial and BigIdeasDB pricing pages, read October 4, 2026. First year is the listed monthly price times 12 where billing is monthly, in USD before tax and promotions.

A year-old comment from a post in r/SaaS, on the risks of paid idea finding platforms in general: paying gives "a false sense or making progress toward your goal", and "with so many ideas to choose from, you are very likely to jump to another idea as soon as difficulty shows up."

A large part of the ideas you have might not be worth pursuing. That is the main reason to check them first. In the Preuve benchmark study (6,000+ ideas analyzed, July 2026), only 17.5% of the ideas scored a 70 or higher. 76.0% scored between 40-69.

So if you have 2-3 ideas in mind, write them down and check whether there is enough demand for them. If there isn’t, consider paying for one of these tools. It takes less than a minute to Reality Check an idea for free, but don’t forget to talk to potential buyers as well (here is a guide on how to validate a SaaS idea). If your ideas die on "nobody pays", there are free alternatives like browsing Starter Story. If they die on "nobody cares", consider investing in BigIdeasDB (lifetime from $99).
