Best Free Streaming Software Compared: OBS vs Streamlabs vs Moblin vs TVU Anywhere

Why "best streaming software" isn't one answer

Most "best streaming software" lists assume you're at a desk with a gaming PC. If that's you, great — but if you're doing IRL content on your phone, or you're trying to get a stable signal from somewhere with sketchy WiFi, the "best" tool changes completely.

This isn't OBS vs Streamlabs vs Moblin as a competition with one winner. It's four genuinely different tools built for different jobs — desktop capture, an all-in-one desktop suite, phone-first IRL, and bonded-cellular mobile broadcast. Picking based on your actual format saves you money and frustration.

OBS Studio — the free desktop standard

OBS (Open Broadcaster Software) is free and open source, with no watermarks, no recording limits, and no features locked behind a paywall — the entire tool is free for personal, educational, or commercial use.

It runs on Windows 10/11, macOS 11 (Big Sur) or later on Intel or Apple Silicon, and Linux. OBS doesn't publish strict minimum/recommended spec tiers — how much power you need depends on your resolution, frame rate, and encoder choice — so it runs the Auto-Configuration Wizard on first launch to set sane defaults for your specific hardware.

OBS handles camera, screen, game capture, and overlays in one canvas, and it connects directly to Twitch, YouTube, and other RTMP-based platforms by pasting in your stream key. The tradeoff for all that control is a learning curve — it's a blank canvas, not a guided wizard, past the initial setup.

• Cost: completely free, always
• Best fit if you're at a desk and want full control, and don't mind a setup learning curve
• Platforms: Windows, macOS, Linux

Streamlabs Desktop — OBS's engine with a built-in creator suite

Streamlabs Desktop is built on the same open-source engine as OBS, but wraps it in a friendlier interface plus a bundle of built-in tools: overlay/theme library, alert boxes, a moderation bot (Cloudbot), and a tip page with no platform fee on the free tier.

The free version covers a full single-platform stream, including Dual Output (one horizontal + one vertical platform at the same time, for free). Going beyond that — three or more simultaneous destinations, unlimited multistreaming, watermark-free clip/video exports, premium overlay themes, and the bundled Talk Studio / Cross Clip / Video Editor apps — requires Streamlabs Ultra, priced around $27/month or roughly $189/year.

In plain terms: if you're streaming to one platform (or one + one vertical), free Streamlabs does the whole job. The subscription only matters once you want to multistream to three-plus destinations or want the extra apps.

• Cost: free for single-platform (or one horizontal + one vertical); Ultra subscription (~$27/mo) for full multistreaming and premium extras
• Best fit if you want OBS's engine with less setup and built-in alerts/overlays out of the box
• Platforms: Windows, macOS

Moblin — free, phone-first IRL streaming

Moblin is a free, open-source iOS app (with basic Mac support) built specifically for IRL streaming — no desktop rig, no capture card, just your phone. It's MIT-licensed, so it's genuinely free with no watermark, no time limits, and no locked features; the only "purchases" are cosmetic app icons to support the developer.

It streams via RTMP, RTMPS, SRT, SRTLA, RIST, or WHIP to Twitch, YouTube, Kick, Facebook, or straight into OBS, at up to 4K/60fps with H.264 or H.265. The feature that matters most for IRL: SRTLA connection bonding, which combines your cellular data and WiFi (and Ethernet, if you have it) at the same time so one flaky connection doesn't kill your stream.

Moblin is a strong first pick for anyone doing phone-first content, because it was built for exactly that use case instead of bolting mobile support onto a desktop-first tool.

• Cost: completely free, open source
• Best fit if you're streaming IRL/mobile and want connection bonding without paying for it
• Platforms: iOS (basic Mac support)

TVU Anywhere — free app, professional-broadcast pedigree

TVU Anywhere is the odd one out on this list: it's a free download on iOS, Android, and Windows, but it comes out of TVU Networks' professional broadcast gear — the same bonded-cellular technology TV news crews use for live field reporting.

The app itself doesn't require any of TVU's paid hardware to go live — you can stream directly to Twitch, YouTube, Facebook, and other destinations from the app. Its core strength is the same idea as Moblin's SRTLA bonding, but built on TVU's own ISX (Inverse Statmux) technology to aggregate 4G/5G and WiFi, plus HEVC encoding down to sub-second latency and Center Stage AI auto-framing on iPad Pro.

Worth knowing before you pick it: TVU's broader ecosystem (professional receivers, TVU Server, and the newer TVU Go product with $29–$69/month plans for extended streaming hours and more simultaneous destinations) is aimed at broadcast and production teams, not hobbyist streamers — so some of what you'll find researching "TVU" is enterprise pricing that doesn't apply to the free Anywhere app itself. Stick to the free app unless you specifically need TVU's professional receiver hardware.

• Cost: free app download; TVU's related professional hardware/subscriptions (TVU Go, receivers) are separately priced for broadcast teams
• Best fit if you're mobile in weak-signal conditions and want broadcast-grade bonding without buying hardware
• Platforms: iOS, Android, Windows

Side-by-side: which one fits your format

If you strip away the marketing, the decision comes down to where you're broadcasting from and how bad your connection might be:

• At a desk, want full control, don't mind a setup curve → OBS Studio
• At a desk, want alerts/overlays/tip page built in with less setup → Streamlabs Desktop (free tier covers single-platform)
• On your phone, IRL, want free connection bonding → Moblin
• On your phone or tablet, IRL, in genuinely weak-signal conditions, want broadcast-grade bonding tech → TVU Anywhere
• None of these cost anything to start. The paid tiers (Streamlabs Ultra, TVU's broader ecosystem) only matter once you're multistreaming to several platforms at once or need production-team features — not for going live for the first time.

Don't chase all four at once

The most common mistake — also covered in the IRL vs. desktop gear guide — is running software built for a format you're not actually in. A desktop streamer chasing bonded-cellular apps is solving a problem they don't have; an IRL streamer wrestling with OBS scene collections at a desk they don't sit at is doing the same thing in reverse.

Pick the one tool that matches your actual setup, get comfortable with it, and only add complexity (multistreaming, a second app, a paid tier) once you've outgrown the free version — not before.
