If you already have a gaming PC, the simplest defensible free setup is OBS Studio running on that computer and sending your gameplay to YouTube through its encoder workflow. You avoid a streaming-software subscription and a cloud-hosting bill, but your PC, electricity supply and internet connection must remain available.
A 24/7 live broadcast is not automatically a complete 24-hour replay. YouTube says a stream longer than 12 hours may not be captured as an archive, so plan for shorter sessions and a local recording if preserving the gameplay matters.
Check what you already have
Before installing anything, decide what you mean by “24/7”. You might want one live page that viewers can return to at any time. You might instead want a sequence of gaming sessions that runs throughout the day, with each session available as a replay. Those are related, but they are not the same outcome on YouTube.
For the free local setup, you need:
- A gaming PC capable of running the game and OBS at the same time.
- A stable internet connection with enough upload capacity for the settings you choose.
- A YouTube channel that is eligible for live streaming.
- A game that can remain at an appropriate screen without requiring constant input, or an operator who can keep playing.
- Enough electricity and a way to keep the computer from entering sleep mode.
- Storage space if you plan to record locally.
YouTube’s live-streaming eligibility guidance says the channel needs verification and must not have a live-streaming restriction from the previous 90 days. The same guidance currently says a person must be at least 16 to livestream. Check the official page before you begin because platform requirements can change.
You do not need a camera for a gameplay stream. Existing headphones can be enough for monitoring, and a microphone is optional if you want commentary. YouTube lists headphones and an external microphone among typical gaming-stream equipment, but neither is required simply to send a game from OBS to YouTube.
It is also worth checking the practical condition of the PC. A machine that plays a game smoothly for an hour may still become unstable after running the game, OBS and a recording for a much longer period. Look at available disk space, cooling, power settings and whether the game pauses, logs out or displays private information when left unattended.
Install OBS Studio and choose the encoder workflow
OBS Studio is free and open source. Download it from the OBS Project help portal, rather than treating a third-party download page as necessary. OBS is the local encoder in this arrangement: it captures the game, combines any overlays or audio, encodes the result and sends it to YouTube.
After installation, open OBS and work through the basic setup without changing settings simply because another creator uses them. Encoding settings depend on the game, the graphics hardware, the output resolution and the quality of the connection. YouTube’s encoder settings guidance provides the platform’s current recommendations for supported settings and ingestion.
The useful distinction is between a local encoder and a cloud-hosted encoder. OBS on your gaming PC costs no software subscription, but the computer must stay powered and capable of doing the work. A cloud arrangement may let the home gaming PC switch off, but it needs a way to receive or provide the game video and should not be called free without checking its current price, gaming capability, limits and operating terms.
For most people who already have a gaming PC, OBS is the clearest starting point because it removes another service from the chain. There is no need to add an unverified utility or a separate streaming application just to connect OBS to YouTube. If you want to understand why sending an already encoded file through another encoder can reduce quality, see this explanation of why re-encoding ruins quality.
Create a simple scene first. Add the game as a source, confirm that the game appears in the preview, and add only the audio sources you actually want viewers to hear. A complicated scene with browser sources, alerts, music players and animated overlays creates more things that can fail while you are away.
For an unattended channel, simplicity matters more than decoration. Use a clear starting scene, remove notifications that could reveal private messages, and test what appears when the game is closed or loses focus. If the game sometimes returns to a desktop or login screen, that screen may remain live until someone intervenes.
Send gameplay to YouTube
Open YouTube Studio and use the Live Control Room to create or select an encoder stream. YouTube’s encoder workflow describes the general sequence: create the stream, copy the server details and stream key into the encoder, start the encoder, check the preview and stream health, then complete the go-live step if YouTube prompts you.
In OBS, open the stream settings and select YouTube if the available integration suits your setup. Otherwise enter the server URL and stream key supplied by YouTube. Prefer RTMPS, which YouTube recommends for ingestion. Treat the stream key like a password. Anyone who obtains it may be able to send content to your channel, so do not paste it into a public screenshot, tutorial or shared document.
Start with an unlisted or private test if you are unfamiliar with the workflow. Watch the YouTube preview while checking the game image, game audio, microphone level and any music you have added. A picture that looks fine in OBS can still have an audio balance that is uncomfortable for viewers.
Once the preview is behaving properly, start the encoder and watch the health indicators in Live Control Room. YouTube recommends monitoring the live stream’s audio and video quality. Do not treat the first successful connection as proof that the setup can run overnight. Let it operate long enough to expose heat, storage, connection or game-session problems before making it a public 24/7 channel.
The stream title, description and visibility should be prepared before you leave the computer unattended. If the stream is intended to continue as a scheduled programme, make the schedule clear to viewers. A schedule cannot keep a local encoder running, however. It tells people what to expect; it does not replace monitoring or recovery planning.
Do not build the workflow around repeatedly copying the stream key into different tools. Keep one documented configuration, restrict access to it and rotate the key through YouTube if you believe it has been exposed. The exact controls may move as YouTube Studio changes, so use the current official instructions when the labels differ.
Understand local uptime dependencies
When OBS runs on your gaming PC, every local dependency becomes part of the broadcast. A power cut stops the encoder. A router restart interrupts the upload. A Windows update can restart the computer. A graphics-driver failure can close the game or leave OBS with a blank capture. A game crash can leave viewers watching a frozen frame or an empty scene.
That is the central trade-off of the free route. You save a recurring service cost, but you take responsibility for the computer and its surroundings. The setup is practical when the PC already exists, the room has dependable power and someone can check the channel. It is a weaker fit when the computer is also needed for work, sits in a room that becomes too hot, or cannot be left running safely.
Use the following as an operating check rather than a promise of uninterrupted service:
| Area | What to check before going live | What can interrupt the stream |
|---|---|---|
| PC power | Disable sleep and confirm the computer can stay on safely | Power cut, restart or overheating |
| Game | Test the selected mode without constant input | Crash, logout, pause screen or update |
| OBS | Confirm the correct scene, audio and encoder profile | Application crash, capture loss or high system load |
| Internet | Test upload stability and watch stream health | Router failure, congestion or provider outage |
| Storage | Leave room for the local recording | Disk fills and recording stops |
| Human checks | Decide who will inspect the stream | A problem remains live until someone notices |
The table does not provide a universal resolution or bitrate because there is no single setting that suits every game, graphics card and connection. Choose a configuration that the PC can encode reliably while the game is running, then verify it in YouTube’s health display. Lowering output complexity may be more useful than chasing a setting that makes the game stutter.
Power management deserves a specific test. Make sure the display turning off does not put the computer to sleep, and check whether the game continues when the monitor is not being watched. If you use a laptop, check its behaviour when connected to power for a long period. Do not assume that a familiar desktop setting applies after an operating-system update.
Internet stability is more important than a speed-test result taken once. An upload can appear fast while still dropping packets or changing quality later. Watch the stream from another connection when possible, because the local OBS preview does not show the complete path to viewers.
If the channel needs attention outside your normal hours, create a small runbook. Write down how to check whether OBS is running, where the stream key is stored, how to restart the game and which YouTube page shows the live health information. This does not automate recovery, and it does not guarantee that another person can fix every failure, but it turns a vague responsibility into a repeatable check.
For ideas about planning viewer expectations, the guidance on setting up a 24/7 stream schedule is relevant even when OBS remains the encoder. For connection failures, also read what happens when a 24/7 stream loses internet. The same basic distinction applies to gaming: a stream can reconnect only if the local components and the operator’s recovery plan allow it.
Plan around YouTube’s 12-hour archive limit
A live stream and its replay are separate things to plan. YouTube says streams shorter than 12 hours can be automatically archived, while a longer stream may not be captured at all. Its DVR guidance also says rewind can be limited or unavailable when a stream exceeds 12 hours.
That means a single broadcast that remains live for a full day is not a dependable way to create a complete day-long replay. The live page may serve viewers during the broadcast, but you should not tell viewers that every minute will definitely be available afterwards.
There are two sensible operating patterns:
| Pattern | Live experience | Replay position | Main cost |
|---|---|---|---|
| One long broadcast | One continuous live destination | Archive may be incomplete or absent beyond YouTube’s 12-hour guidance | Simpler scheduling, weaker replay certainty |
| Shorter sessions | Several broadcasts across the day | Better fit for YouTube’s automatic archive behaviour | More starts, titles, checks and handovers |
Choose the first pattern when continuity for live viewers matters more than a complete replay and you can monitor the local setup. Choose the second when viewers need to watch missed gameplay later, or when you want each session to have its own title and description.
The exact handover needs testing. End one session cleanly, confirm that YouTube has processed it as expected, then start the next encoder session. A planned gap is preferable to assuming that a long broadcast will produce a perfect archive. If you use a schedule, tell viewers when the next session begins rather than presenting the operation as guaranteed continuous uptime.
YouTube’s archive behaviour is a platform constraint, not an OBS setting. Changing the encoder, adding a second scene or using a different title will not remove it. Check the current archive guidance from YouTube before designing a workflow around replay availability.
Keep a local recording and split sessions
A local recording gives you another copy of the gameplay, but it introduces its own requirements. OBS must write the file while it is encoding and streaming, so the recording needs storage space and can add load to the computer. Test the chosen recording format and location before relying on it for a long session.
YouTube recommends checking that the local archive file is growing during a stream. Do that early rather than discovering after a power failure that the file stopped at the beginning. Watch available disk space as well. A recording that fills the drive can affect the game, OBS and the wider computer.
For an around-the-clock channel, split recordings into manageable sessions instead of creating one enormous file. Shorter files are easier to inspect, copy and edit. They also make it clearer which period was affected if the connection or game fails. The precise file size depends on the recording settings, game image and duration, so measure your own test rather than relying on a generic estimate.
A local recording is not a substitute for a second machine or backup power. If the gaming PC loses electricity, both the stream and the recording stop. If the drive fails, both the live operation and the local copy may be affected. Keep important finished sessions on separate storage if they have lasting value.
When you split sessions, label them consistently with the game, date and session period. Keep the YouTube title and local filename aligned enough that you can identify a clip later. If you publish edited highlights, review the recording for private information, copyrighted audio and accidental desktop captures before uploading it.
The free setup is strongest when you already own the hardware and accept that monitoring is part of the job. It is not a free source of electricity, storage or internet access, and it does not remove the need to respond when the game, PC or connection fails.
Before committing, compare the operating options on the pricing page. When the file and channel are ready, start free — 24-hour trial, no card.
FAQ
Can I stream on YouTube 24/7 for free?
You can use OBS Studio on an existing gaming PC without paying for streaming software, then send the gameplay to YouTube through its encoder workflow. You still use electricity, internet access, computer hardware and storage, and none of those costs disappear. The setup can run for long periods, but it depends on local uptime and does not guarantee an uninterrupted broadcast.
Can I use OBS to stream a game to YouTube?
Yes. Add the game as a source in OBS, connect OBS to the encoder stream created in YouTube Live Control Room, protect the stream key and check the preview before going live. YouTube describes encoder workflows as commonly used for gaming and gameplay with overlays.
Will YouTube save a 24/7 livestream?
Do not rely on YouTube to preserve a complete broadcast longer than 12 hours. YouTube says a stream exceeding 12 hours may not be captured at all, and DVR rewind can also be limited or unavailable. Split sessions and keep a local recording when a replay matters.
Is a cloud encoder better than OBS on a gaming PC?
It can be a better fit if you need the home gaming PC switched off, but the service must still receive the game video and may add a subscription or other limits. OBS is usually the simplest starting point when you already have suitable local hardware. Compare recovery options, monitoring needs, gaming support and current terms rather than assuming that a cloud route is free or more reliable.
