Pulsar

Pulsar is a free, open-source app combining remote desktop control with low-latency game streaming. The maker describes it for gamers and IT or support teams connecting to servers, client machines, and personal computers. Remote desktop tools include access by ID and one-time password, unattended access, file transfer, clipboard sync, session chat, multi-monitor support, and remote restart. Connections try peer-to-peer first and switch to a relay when necessary. Game streaming supports hardware H.265 or AV1 encoding at up to 120 fps, HDR, ultrawide displays, and multichannel audio. Gaming controls include Xbox and PlayStation controller mapping and adaptive bitrate. Downloads are offered for Windows, macOS, Linux, and Android, with listed requirements of Windows 10/11, macOS 12+, Linux with glibc 2.31+, or Android 7+. The iOS App Store release is described as in development. The maker says Pulsar needs no account and has no telemetry or ads. Encryption keys are generated on user devices, so the maker says neither its server nor relay can decrypt traffic. Users can run their own relay and device identity server with a Docker command.

Pulsar brings remote support features and game streaming into one free, open-source app. Its available platforms are Windows, macOS, Linux, and Android; the iOS release is still in development.

Pulsar suits gamers seeking game streaming and IT or support teams needing remote access to computers. It is available for Windows, macOS, Linux, and Android.

Pulsar is a free, open-source application that puts remote computer support and game streaming in the same package. It suits gamers who want high-quality streaming alongside people who administer PCs or servers, especially those who value self-hosting and privacy. The trade-off is a technically demanding setup and a still-narrower device reach than some rivals.

Overview

Pulsar covers two jobs that are usually handled by separate tools. Its remote-desktop side supports ID and one-time-password connections, unattended access, file transfer, clipboard synchronization, session chat, multiple monitors, and remote restart. That combination is practical for helping clients, reaching a home machine, or maintaining a server without requiring someone at the keyboard.

Its game-streaming side targets demanding play rather than basic screen sharing. Hardware H.265 or AV1 encoding can reach 120 frames per second, with HDR, ultrawide displays, and multichannel audio. Xbox and PlayStation controller mapping, plus adaptive bitrate, address the input and changing-network concerns that matter during play. Connections attempt direct peer-to-peer communication and switch to a relay when that fails, so restrictive networks do not automatically end a session.

Key features

Remote support and streaming in one app

The shared application is Pulsar's clearest advantage. Support teams can use unattended access and remote restart, while players get high-frame-rate video and controller support without maintaining separate clients. A single tool is less compelling if your work is limited to only one of those tasks, but it is a strong fit for households or small teams that need both.

Privacy, verification, and control

Pulsar requires no account and carries no telemetry or advertising. It says encryption keys are created only on user devices, preventing the server or relay from decrypting traffic. The entire codebase is published on GitHub under GPLv3, and releases provide SHA-256 checksums, signatures, and GPG signing. Those choices make the software easier to inspect and validate than a closed, account-first service.

Self-hosting

A Docker command can run your own relay and device-identity server. That is valuable for organizations with infrastructure or data-residency requirements, but it also shifts deployment, maintenance, and availability responsibilities to the operator. Users seeking a managed support service should look elsewhere.

Pricing

There is no trial because the only plan is permanently free. The plan has no published seat or usage charge, making it suitable for personal access, volunteer support, and teams willing to operate their own infrastructure. Commercial users should still assess their support and hosting obligations before standardizing on it.

Platforms

Host applications run on Windows, macOS, and Linux; clients run on those systems plus Android. Downloads support macOS 12+, Windows 10/11, Linux with glibc 2.31 or newer, and Android 7 or newer. The iOS App Store release is in development, so iPhone and iPad users cannot make Pulsar their client today. Hardware video-encoding support is required, with 4 GB of RAM (8 GB recommended) and 5 Mbps network speed; gaming is specified at 15 Mbps or more. Maximum resolution is 4K, and multi-monitor use is supported.

Who it's for

Choose Pulsar if you want one open-source tool for game streaming and remote assistance, need unattended access or file and clipboard exchange, or prefer no account and no telemetry. It is particularly attractive to technically capable gamers, IT departments, and support operators who can deploy a Docker relay or identity server. It is a poor match for iOS-first households, users who want a hosted service with minimal administration, or anyone whose hardware lacks supported video encoding.

Pros and cons

• Pros: One free application combines serious support controls with 120-fps, HDR-capable streaming.
• Pros: No account, ads, or telemetry, with device-only key generation and public GPLv3 source.
• Pros: Peer-to-peer connections, relay fallback, 4K output, and multi-monitor support cover varied networks and workstations.
• Pros: Self-hosted relay and identity services provide control over infrastructure.
• Cons: iOS is not supported yet, limiting mobile coverage.
• Cons: Self-hosting and hardware-encoding requirements add operational and compatibility work.

Alternatives

For a broader comparison, see Game Remote Play Software and Remote desktop software.

• Moonlight Game Streaming is the better pick for a dedicated, completely free game-streaming client with iOS support and no paid versions.
• Moonlight Web suits users who want browser access or self-hosting, with no accounts, subscriptions, or paid tiers.
• Parsec is worth choosing when you need a freemium service with a personal-use tier and an optional Individuals (Warp) plan at $8.33 a month.
• Artemis Android is an Android-only open-source GameStream client.
• Chiaki-ng is the focused choice for a free, open-source PlayStation Remote Play client.
• PeaSyo is a permanently free option spanning desktop and mobile platforms.
• Razer PC Remote Play is a free Android, iOS, and Windows alternative associated with Razer Cortex Mobile.
• Steam is the broader game platform, with game and content prices varying by purchase.

Verdict

Pulsar is a strong recommendation for privacy-conscious gamers and support teams that want capable streaming and remote administration without subscription costs. Its open-source design, self-hosting path, and extensive session controls are compelling. Look elsewhere if iOS access, a managed cloud service, or a narrowly focused PlayStation or browser client matters more than having both functions in one technically oriented tool.
