If you've narrowed your multistreaming search to Restream, Castr and StreamTiler, you've picked three genuinely capable tools — but they're built around different ideas about what a streamer needs. This comparison walks through how they differ on approach, features, flexibility and cost, so you can match the right one to your setup.

We're keeping the competitor notes conservative and capability-focused rather than quoting specific prices or plan limits, because those change often. As of August 2026 the descriptions below reflect each product's general positioning — confirm the current details on Restream's and Castr's own sites before you decide.

At a glance

The quickest way to think about the three:

Approach and philosophy

Restream is designed to be an all-in-one live studio. You can bring the whole production into the browser — remote guests, branding, layouts — and simulcast the result, which is ideal for talk shows and interviews where you don't want to run OBS at all.

Castr treats live streaming as part of a broader video-delivery stack. Alongside multistreaming it offers hosting, embedding and CDN delivery, so it appeals to people who also need streams on their own website or want a "live" channel that's really a scheduled loop.

StreamTiler is built around flexibility and cost. The same account can push a stream from StreamTiler's cloud (so it keeps running when your computer is off) or straight from your own PC using an included Windows agent — and you can mix both. The idea is that you shouldn't have to pay for cloud bandwidth you don't need, or give up cloud convenience when you do.

Platform coverage

All three cover the destinations that matter: YouTube, Facebook, Twitch, Kick, TikTok and custom RTMP, which is the baseline any serious multistreamer expects. One detail worth calling out on StreamTiler's side is that Facebook connects through the official Page API rather than manual stream keys, which keeps that connection stable — Facebook stream keys have historically been a common source of "why did my stream drop" headaches. For your specific niche platforms, check each provider's current destination list, since coverage does get added and occasionally removed.

Production features

This is where the philosophies diverge most. If you want a built-in studio — invite a co-host, drop in overlays and lower-thirds, share your screen, all in the browser — Restream is the most complete out of the box. Castr includes production-adjacent features too, with its hosting and pre-recorded-to-live capabilities standing out.

StreamTiler takes the opposite stance: rather than replacing your production software, it works behind whatever you already use — OBS, Streamlabs, vMix or any RTMP encoder — and focuses on relaying that feed reliably to every destination, with auto-retry if a platform connection drops and scheduling so broadcasts can start on their own. If you already have a production workflow you like, that's a feature, not a gap.

Flexibility

Cloud-only tools are simple but rigid: everything runs on the provider's servers and you pay accordingly. StreamTiler's cloud-or-local model is the main flexibility differentiator here — on a fast connection you can stream locally to save on cost, then switch to cloud for a 24/7 channel or when you're streaming from a laptop on the go. Restream and Castr are primarily cloud-based services, which is exactly what many creators want; it's just a different trade-off.

Pricing

Pricing is the hardest thing to compare fairly, because all three change their plans and because they bundle different things. Rather than quote numbers that may be stale, here's the shape of it: StreamTiler positions itself at the low-cost end, starting at $3/mo on month-to-month terms with no long lock-in, which makes it one of the cheaper ways to start multistreaming. Restream and Castr are more feature-bundled platforms and price accordingly — you're often paying for the studio or the hosting/CDN layer as well as the multistreaming. Always price out the specific plan that matches your destination count and feature needs on each provider's site before committing.

Reliability and reconnection

For anything live, the feature that matters most is the one you never see: what happens when a single destination drops. A platform can reject a connection mid-stream for its own reasons — a token expires, its ingest server hiccups — and the question is whether that takes down just that destination or interrupts your whole broadcast. All three services run their fan-out on managed infrastructure rather than your PC, which is already a big reliability win over local duplication. StreamTiler specifically auto-retries a dropped destination and reconnects it without touching the others, and its Facebook connection through the official Page API sidesteps the expired-stream-key problem that causes a lot of mid-stream Facebook drops. When you're comparing, look for per-destination reconnection rather than an all-or-nothing restart.

Which fits which creator?

It's easier to decide with concrete situations in mind:

Most people are some blend of these, so weight the scenario you're in most often.

Which one should you choose?

Choose Restream if your priority is a zero-install browser studio for guest-heavy shows and you want production and simulcasting in one place. Choose Castr if you need video hosting, embedding or pre-recorded-as-live alongside multistreaming. Choose StreamTiler if you want the lowest entry price, the flexibility to stream from the cloud or your own PC, and reliable fan-out behind the encoder you already use.

None of these is objectively "best" — they're optimized for different creators. The honest answer is to start from your own workflow: if you live in OBS and care about cost and flexibility, StreamTiler fits; if you want an all-in-one studio, Restream; if you're building a video product, Castr.

The bottom line

Restream, Castr and StreamTiler all deliver on the core promise of going live everywhere at once. They differ in what surrounds that: a studio, a hosting stack, or flexible cloud-and-local streaming at a low price. If the last of those sounds like your priority, StreamTiler starts at $3/mo — and if you're still mapping the landscape, our roundup of the best Restream alternatives in 2026 covers four more options.
