The honest verdict
These two are both active, so this is a real choice. PainOnSocial is the focused one: you pick subreddits, choose a 7, 30 or 90 day window, and it returns AI-ranked pain points with real quotes and direct Reddit links, plus solution ideas. It is a monthly subscription, $19 for 20 scans or $49 for 300 (painonsocial.com, 25 September 2026).
BigIdeasDB is the broad one. Its site says it has analysed over 1M complaints, reviews and discussions from G2, Capterra, Reddit, Upwork and the app stores, and it adds build tooling such as BuildGuide, an MCP server and free calculators. Its findings are summarised across many reviews, and individual reviews link to their source. It costs $49 a month, or $99 to $349 once for lifetime access (bigideasdb.com, 25 September 2026).
The honest verdict: pick PainOnSocial if your market lives in a few subreddits and you want the problems in them now. Pick BigIdeasDB if your market is software buyers who leave reviews on G2 and Capterra, or you want build tooling alongside the research. Neither is strictly better; they trade depth on your own communities for breadth across review sites.
Where IdeaFast fits
A third option, in the interest of full disclosure
Full disclosure: IdeaFast is our own product, so read this with that in mind. IdeaFast does the same job as PainOnSocial rather than BigIdeasDB: it scans the subreddits you choose, clusters the recurring complaints, scores each theme from 0 to 100, and links every pain point to the threads it came from.
The differences are in how you pay and how you start. IdeaFast sells one-time scan packs rather than a subscription: $19 for 40 scans or $49 for 100, the scans never expire, the research pages are readable without signing up, and the first scan is free with no card. If you scan most days, PainOnSocial's 300 scans a month for $49 is cheaper per scan; if you need review-site data, BigIdeasDB covers ground IdeaFast does not.
Try IdeaFast freeFrequently asked questions
What is the main difference between PainOnSocial and BigIdeasDB?
PainOnSocial scans the Reddit communities you pick and scores the pain it finds. BigIdeasDB is a ready-made database of complaints and reviews from G2, Capterra, Reddit, Upwork and the app stores, with build tooling on top.
Which is cheaper, PainOnSocial or BigIdeasDB?
Monthly, PainOnSocial: $19 a month for 20 scans against BigIdeasDB's $49 a month, and PainOnSocial's $49 plan buys 300 scans. BigIdeasDB also sells lifetime access for $99, $199 or $349 once, while PainOnSocial lists only monthly plans. Prices read on each site on 25 September 2026.
Does either link to the original complaint?
Both do, in different ways. PainOnSocial shows real quotes with a direct Reddit link on each pain point. BigIdeasDB summarises findings across many reviews and links individual reviews to their source, such as G2. Read on each site on 25 September 2026.
Which should I pick for a niche I already know?
If your niche lives in a few subreddits, a tool that scans those communities on demand fits better than a broad database: PainOnSocial does that monthly, and IdeaFast (our product) does it with one-time packs and a free first scan. If your niche is a software category with plenty of G2 and Capterra reviews, BigIdeasDB's database is the faster start.
Which of these two should I pick for finding a SaaS idea?
Pick on verification rather than volume. A bigger pile of complaints is not more useful than a smaller pile you can trace to source. Whichever you trial, test the same thing: pick one claim, try to open the original discussion behind it, and see how much work that takes.
Are these tools direct competitors?
They overlap in outcome and differ in method. PainOnSocial scans Reddit communities on demand; BigIdeasDB sells access to a prebuilt database across several complaint sources, monthly or for life. They are alternatives for the same job rather than like-for-like products, so compare them on sourcing and how fresh the data is.
