3. MX Player
Why it’s good: While originally a free video player/streamer, MX Player has grown into a full OTT service with Hindi & regional web series — including those aimed at adult audiences.
Vibe: Mix of thriller, drama, bold content — accessible (because free or low‑cost) and easy to jump into.
Tip: Use the free tier if you’re exploring; but check whether particular series carry an 18+ indicator.
History: MX Player’s strength lies in volume + variety — giving alternative to the purely premium platforms.
4. Kooku
Why it’s good: Although less mainstream than some big names, Kooku is known for light‑hearted but adult‑oriented Hindi web series with quirky premises.
Vibe: Fun, playful, more on the “entertainment for adult company” side than heavy drama.
Tip: Great if you want something less serious, more escapist. But check user‑reviews because production values vary.
History: Emerged with a niche focus for audiences wanting mature content but with simpler setups.
5. PrimeShots
Why it’s good: A newer entrant with fast‑growing library of Hindi series targeting mature themes — relationships, emotional intensity, urban contexts.
Vibe: Trend‑forward, modern settings, younger cast often, stories about contemporary adult‑life issues.
Tip: Because newer, may have less content than older platforms — but if you like being early adopter, this is fun.
History: Less legacy burden, so freer to experiment with bold themes.
6. Hunters App
Why it’s good: Focused on semi‑urban/rural settings with bold plots — appealing to viewers who want mature stories beyond metro life.
Vibe: Rustic backdrops, dramatic arcs, adult themes layered with regional flavour.

8. Fliz Movies (also known in some places as NueFliks)
Why it’s good: Blends indie‑style adult and bold content in Hindi, mixing suspense, relationship drama, erotic flavour.
Vibe: More offbeat, less mainstream polish — so if you like unconventional stories, this could be interesting.
Tip: Might be hit‑or‑miss in terms of production value — preview a few titles before committing.
History: Started as a smaller platform, grew with focus on niche adult content in Hindi.
9. ALTT
Why it’s good: While ALTBalaji appears as mainstream + adult niche, ALTT is its “bold adult” sibling/streaming brand focusing more explicitly on 18+ content.
Vibe: Direct‑to‑adult‑audience stories, often more provocative, less constrained by typical TV‑style censorship.
Tip: Use it when you want no less than “bold” and you’re specifically comfortable with adult‑themed material.
History: Rebranding to ALTT shows how platforms are segmenting audiences — adult vs general.
10. 4SidesPlay
Why it’s good: While its focus is more regional (South India languages: Telugu/Tamil/Kannada/Malayalam) rather than exclusively Hindi, 4SidesPlay is emerging with original web‑series, inclusive of bold and mature themes such as Seeti Bajaye Raat Bhar, Shikaar Ki Rani hot web series.
Vibe: A mix of language‑diverse settings, culturally rich stories, and increasingly adult‑oriented formats. It adds freshness if you are open to content beyond just Hindi.
Tip: If you don’t mind moving slightly out of pure Hindi‑only territory, this platform gives you a flavour of regional narratives which often push boundaries differently.
