Moviebase vs BetaSeries (2026)
Updated Sep 18, 2026
Last checked 2026-09-18, live re-verified against both sites via the built-in browser pane. Moviebase ships weekly — re-verify specifics before relying on the feature list below.
Moviebase and BetaSeries both track movies and TV rather than streaming them, but they come from very different traditions — Moviebase is a modern, discovery-first app built around filters and multi-source ratings; BetaSeries is a decade-old French community site (BetaSeries SAS) built around a forum, a blog, and a calendar, with the tracker as one part of a bigger community product.
What they have in common
•
Both track movies and TV, both are explicit that they are trackers, not streamers — BetaSeries's own App Store listing states plainly "you can't watch nor download your shows and movies," the same design line Moviebase draws.
•
Both show where a title is available to stream — Moviebase filters by the services you pay for; BetaSeries lists SVoD platform availability per episode and movie.
•
Both are free to download and use, with no in-app purchases surfaced on their respective App Store listings as of this check.
•
Both run editorial content alongside the tracker — Moviebase publishes guides and comparison pages from moviebase.app; BetaSeries runs a TV-news blog and articles as a core part of its own site.
Where they differ
What kind of product it is
Moviebase is a discovery-first tracker — genre/rating/runtime/provider filters, studio and keyword search, TMDB/IMDb/Rotten Tomatoes ratings side by side, home-screen widgets, and a lighter social layer (profiles, follows, comments, inbox). BetaSeries is a community-and-editorial platform first — a public forum, member polls, badges and experience points for participation, an activity feed of what the community is watching, and a blog of TV news — with tracking, calendars and notifications built on top of that.
Platform
Moviebase is phone-only — native iOS and Android apps, with moviebase.app serving as marketing and share pages only; there's no way to use the tracker itself in a browser. BetaSeries is a full website you can actually track in — betaseries.com is the product, with sign-in, your calendar, your profile and the community all live in the browser, alongside dedicated iOS and Android apps that mirror the same account.
Language and market
BetaSeries's site ships in 14 languages (French, English, German, Spanish, Italian, Dutch, Polish, Swedish, Portuguese, Turkish, Ukrainian, Russian, and Brazilian Portuguese, per its own language switcher) and defaults to French — it reads as a France-first product with English as a strong secondary market. Moviebase's marketing site is English-only at the top level, though in-app title and episode details are localized to the device's language via TMDB.
Content scope and ratings
Moviebase pulls ratings from three sources side by side — TMDB, IMDb, and Rotten Tomatoes — as one of its headline features. BetaSeries's App Store listing describes rating and commenting on movies, shows and episodes within its own community, without the same three-source comparison view.
Monetization
Moviebase: free tier is ad-supported but unlimited for tracking; Premium price stays undisclosed on the site, revealed only at checkout (consistent with every prior GROWTH check of Moviebase). BetaSeries: its App Store listing shows no in-app purchases at all, and this check could not locate a live, English-language premium pricing page on betaseries.com — a paid "Premium" account is referenced in BetaSeries's own community forum, but its current price isn't confirmed here and shouldn't be assumed.
Which one, if you have to pick
•
Pick Moviebase if you want a single polished mobile app with strong multi-source ratings and provider filtering, and you're fine with undisclosed Premium pricing in exchange for an unlimited free tier today.
•
Pick BetaSeries if you want a browser-usable tracker with a real community around it — forum, polls, badges, a TV-news blog — especially if French is your first language, since that's the product's home market.
•
Neither is built for a household's decision. Moviebase's social layer is follows and comments; BetaSeries's is a public forum and activity feed. Both are still one account deciding for itself. CouchReel's comparison pages cover the household-decision gap directly, if that's the one you're trying to close.
