Measured on six things

Explore over 100.000 subreddits and view them as customizable media galleries. SubRedds also lets you view Reddit users posts, even if they are hidden

Security

HTTPS and HSTS are on, and the local-first 'nothing is uploaded' model is a genuine privacy plus. But CSP, frame protection, Referrer-Policy, SPF and DMARC are all missing — 4/12 on headers.

SubRedds

About this app

SubRedds is a map of Reddit. It keeps track of more than 100.000 subreddits, SFW and NSFW, and shows for each one how many members it has, how many posts a day it gets, how old it is and when it was last checked. The list can be searched, filtered by size, activity and content rating, and sorted by any column, so finding the biggest, busiest or newest communities on any topic takes seconds. Every subreddit opens as a gallery of all its pictures and videos, newest first, loading as you scroll, all the way back through the public Reddit archives. Any Reddit profile can be browsed the same way, across every subreddit the person has posted in. Switches for pictures, videos, media posts only, duplicates and deleted posts, and a layout of one to eight columns with your choice of thumbnail ratio, make the gallery yours. Browsing needs no account. A free account adds a sidebar of saved subreddits and users, sorted into sections you name, and a heart that keeps any post.

Key features

1Searchable, sortable map of 122,450+ subreddits with members, daily posts, age, growth and content-rating filters.
2Infinite-scroll media gallery for any subreddit or user profile, with toggles for pictures, videos, duplicates and deleted posts.
3Local-first browsing with no account required; free account adds saved-subreddit sidebar sections and a post heart.

Target customer profile

Drawn from the product itself, not from a survey.

Demographic

Reddit power users, lurkers, and researchers

Pain points

Reddit's native search and feeds make it hard to find niche or dormant subreddits; deleted content vanishes.

Primary needs

Fast subreddit discovery by size/activity and access to archived media that no longer exists on Reddit.

Demographic

Content curators and social media marketers

Pain points

Manually tracking trending communities and gathering visual assets across subreddits is tedious.

Primary needs

Gallery browsing, custom category feeds, and stable links to archived posts for reference and repurposing.

Demographic

Data-curious hobbyists and OSINT enthusiasts

Pain points

No easy way to browse a single user's complete posting history or quantify subreddit growth and age.

Primary needs

User profile archives, growth/age sort metrics, and privacy-friendly local data storage.

Scout Review

Written by AI from measured evidence, scored out of 100.

SubRedds is a genuinely useful idea executed with indie-tool pragmatism. It maps 122,450+ subreddits with size, activity, age and content-rating data, and turns any subreddit or user profile into an infinite-scroll media gallery — a real answer to Reddit's weak native discovery and vanishing deleted content. The local-first, no-account-required model is a smart trust play. Where it stumbles: the interface is dense to the point of hostility (10-column table, orange button on every row, no onboarding), mobile performance lags desktop badly, and the security headers are half-finished. Accessibility is close but the unlabeled table cells undercut it. The idea has legs; the polish and the business model are the unfinished parts.

Measure by measure

Usability

No-account browsing and a clear free-account value ladder are real strengths, but the control panel is a wall of toggles and there's no visible onboarding or help docs.

Design

Cohesive dark theme and scannable sidebar, but a 10-column table with an orange 'OPEN GALLERY' button on every row is visual noise. Dense, low-contrast, and horizontally scrolling.

Speed

Desktop Lighthouse 91/100 is genuinely quick, but mobile 74/100 with a 4.5s LCP drags it down. CLS 0.003 and 21ms TBT show the layout is stable and the JS isn't choking.

Security

HTTPS and HSTS are on, and the local-first 'nothing is uploaded' model is a genuine privacy plus. But CSP, frame protection, Referrer-Policy, SPF and DMARC are all missing — 4/12 on headers.

Accessibility

Lighthouse 93/100 is solid, but three real failures: low color contrast, links distinguishable only by color, and a large table whose cells lack headers. No a11y statement or multi-language support found.

Growth

A real, specific problem — Reddit discovery and archived-media access are genuinely broken natively — with concrete differentiators (122k subreddits, size/age sorting, user-history galleries). Category has room.

Improvement areas

Dense 10-column table with no visual hierarchy and an identical orange action button on every row.
Mobile LCP of 4.5s lags far behind the 91/100 desktop score.
Missing security headers (CSP, frame protection, SPF, DMARC) and no published pricing or monetization model.

Design & Usability

SubRedds looks like a tool built by someone who uses it daily and designed it for themselves. The dark theme is consistent, the sidebar categories and filter chips are immediately scannable, and the information density is the point — you can compare dozens of subreddits at a glance. The problem is that density has no hierarchy: a 10-column table forces horizontal scrolling, every row ends in an identical orange 'OPEN GALLERY' button, and low-contrast text with tight spacing makes long sessions rough. Usability is stronger than design: browsing needs no account, and a free account adds a saved-subreddit sidebar and a heart for posts — a clean value ladder. But the control panel is a wall of toggles (filter chips, ratio selector, a 'Proxy URL (debug)' field) with no visible onboarding or help docs in the fetched content. A first-timer has to reverse-engineer the interface.

Speed & Security

Speed is a tale of two devices. Desktop Lighthouse lands at 91/100 — genuinely snappy — while mobile sits at 74/100 with a 4.5s LCP and 3.3s FCP, meaning phone users wait noticeably before content paints. The saving grace is stability: CLS 0.003 and TBT 21ms show the layout doesn't jump and the JavaScript isn't choking the main thread. Security is the weakest link. HTTPS is enforced and HSTS is set, and the local-first model ('everything runs in your browser, nothing is uploaded') is a real privacy advantage worth crediting. But the header probe found no CSP, no frame protection, no X-Content-Type-Options, no Referrer-Policy, no Permissions-Policy, and no SPF or DMARC — 4 of 12 checklist points. For a tool that browses arbitrary archived media, the missing CSP and frame protection are the ones that matter most.

Accessibility & Growth

Accessibility scores 93/100 on automated checks, which sounds great until you read the three failures: insufficient color contrast, links distinguishable only by color, and a large table whose <td> cells lack headers. That last one is the killer for a data-table product — a screen reader user navigating the subreddit list gets cells with no context. No accessibility statement or multi-language support was found. Growth is the most interesting dimension. The problem SubRedds names is real and specific: Reddit's native search is bad at surfacing niche or dormant subreddits, and deleted media genuinely disappears. The product's answer — 122,450 indexed subreddits, sorting by size/activity/age, per-user posting-history galleries, and archived media browsing — is a concrete wedge that Reddit's own tools don't offer. The category (Reddit discovery and archival) is fragmented across Redective and Pushshift, and SubRedds' visual-gallery angle is distinct. The open question is monetization: the site shows no pricing, so it's unclear how a free-account model converts.

Conclusion

If you're a Reddit power user, lurker, or researcher who's tired of fighting Reddit's search, SubRedds is worth a bookmark today — it does something the native tools genuinely can't. Go in expecting a power-tool interface, not a guided tour. For the maker: the fastest wins are a mobile LCP fix, table headers on that data grid, and a real CSP. The bigger question is how this becomes a business — there's no pricing page, and 'free account' is doing a lot of work. Nail the monetization story and this moves from clever side project to a product people pay for.

Suggestions for improvement

Add table headers (<th>) to the subreddit data grid — it's the single biggest accessibility win and fixes a real screen-reader failure.
Fix mobile LCP (4.5s): lazy-load below-fold rows and defer non-critical JS to close the gap with the 91 desktop score.
Ship a Content-Security-Policy and frame protection — for a tool rendering arbitrary archived media, these are table stakes.
Add a short onboarding tour or help page explaining the filter chips, ratio selector, and proxy field; the control panel is opaque to newcomers.
