LocalSend Review: Is It a Good AirDrop Alternative?

Quick Verdict: Is LocalSend Worth Using?

LocalSend is worth using if you regularly transfer photos, videos, documents, and other files between devices running different operating systems. It is free, open source, and works across Android, iOS, Windows, macOS, and Linux. It can transfer files over a local network without requiring an internet connection or a cloud account.

Its biggest advantage over AirDrop is cross-platform support. You can use it to send files from an iPhone to a Windows PC, from an Android phone to a Mac, or between computers running different operating systems.

AirDrop remains the simpler option for people who use Apple devices exclusively. It is integrated into the Apple ecosystem, so users do not need to install another application for routine transfers.

Our verdict: Choose LocalSend for flexible file sharing across different platforms. Choose AirDrop when your devices are all part of the Apple ecosystem and convenience is your main priority.

What Is LocalSend?

LocalSend is a free file-sharing application that lets nearby devices exchange files and messages over a local network. Instead of uploading a file to a cloud service and downloading it on another device, LocalSend enables the devices to communicate directly over the network.

The application supports common desktop and mobile platforms, making it useful for people who work across different operating systems. For example, an iPhone owner can transfer photos to a Windows computer without relying on a cloud storage account or a cable-based transfer workflow.

LocalSend is also open source. Its source code and technical documentation are publicly available through the official GitHub repository. This allows developers and security researchers to inspect the implementation, although open-source availability alone does not guarantee that every version is free from vulnerabilities.

LocalSend vs AirDrop: What Is the Difference?

LocalSend and AirDrop solve a similar problem, but their compatibility and network designs differ. LocalSend is intended for communication between supported platforms, while AirDrop is designed for compatible Apple devices.

Feature	LocalSend	AirDrop
Platform support	Android, iOS, Windows, macOS, and Linux	Compatible iPhone, iPad, and Mac devices
Installation	Install LocalSend on supported devices	Built into supported Apple operating systems
Device discovery	Local network discovery methods, including multicast	Bluetooth Low Energy and Apple's peer-to-peer Wi-Fi technology
File transfer	Local network communication through its REST API	Apple's integrated wireless sharing system
Cloud account	Not required	Some features and automatic acceptance behavior depend on Apple Account settings
Internet access	Not required when the local network is working	Nearby transfers can work without internet access; some behavior can use internet connectivity
Cross-platform sharing	Yes, between supported platforms	No general support for Windows or Android devices
Open source	Yes	No, it is part of Apple's proprietary software ecosystem
Best suited for	Mixed-device households, students, and cross-platform workflows	People sharing files within the Apple ecosystem

Apple documents AirDrop as using Bluetooth Low Energy for discovery and peer-to-peer Wi-Fi for transfers. LocalSend follows a different approach based on local network communication. These architectural differences help explain why the applications have different setup requirements and compatibility limits.

How Does LocalSend Work?

LocalSend uses a local-network communication protocol built around a REST API. In its documented default configuration, devices use UDP multicast to announce their presence, then establish communication through TCP using HTTP or HTTPS, depending on the protocol and application configuration.

When LocalSend is running on two compatible devices connected to the same reachable network, each device can discover the other. The sender selects files and initiates a transfer. The receiving device can then respond to the transfer request according to its settings and the application's workflow.

LocalSend's published protocol uses port 53317 by default for multicast discovery and HTTP-based communication. The port can be changed in the application settings when necessary.

For many users, the process is straightforward:

1. Install LocalSend on both devices.
2. Connect the devices to the same local network, or set up a suitable local connection.
3. Open LocalSend on each device.
4. Select the files you want to share.
5. Choose the destination device from the available devices.
6. Accept the incoming transfer on the receiving device when prompted.
7. Check the destination folder or app to confirm the files arrived.

One important detail is that a shared Wi-Fi name does not always mean two devices can communicate with each other. Guest networks, router isolation settings, firewalls, and VPN configurations can block local traffic even when both devices appear to be connected successfully.

Does LocalSend Work Without Wi-Fi or Internet?

LocalSend does not need internet access to transfer files over a working local network. This means an active internet connection is not a requirement for every transfer.

There is an important distinction between Wi-Fi and internet access. A Wi-Fi router can connect devices to each other even when its internet connection is down. If the devices can communicate across that local network, LocalSend may still work.

Using LocalSend without a conventional Wi-Fi router depends on the connection method available to your devices. A suitable personal hotspot or other local network can sometimes provide the necessary connection, but compatibility and routing behavior vary. A hotspot that blocks communication between connected clients will not work as expected.

For reliable results, open LocalSend on both devices before starting the transfer and confirm that they can discover each other. If discovery fails, check the network configuration rather than assuming the internet connection is the problem.

Is LocalSend Safe?

LocalSend is designed to exchange files locally and documents the use of HTTPS for secure communication. Its project documentation also explains that TLS certificates are generated on each device. This is different from sending files through a third-party cloud storage service.

Still, there are several security considerations to keep in mind.

1. Local transfers reduce reliance on cloud services

LocalSend does not require a third-party server to relay ordinary transfers between devices on a working local network. That can be useful when you do not want to upload private photos or documents to a cloud service just to move them to another device.

2. Encryption does not replace careful sharing

HTTPS protects communication in transit, but users should still verify the destination device before approving a transfer. A device name or alias is not proof of identity. On shared networks, avoid accepting unexpected transfer requests.

3. Install the application from a trusted source

Download LocalSend from its official website or its linked project distribution channels. Keeping the application updated is a sensible security practice because updates can address bugs and compatibility issues.

4. Be careful with firewall changes

LocalSend's documentation describes allowing local network traffic on TCP and UDP port 53317 in the default configuration. If a firewall blocks communication, a narrowly scoped rule for trusted private networks may help. Avoid disabling the firewall entirely or exposing the application to the public internet just to make discovery work.

5. Understand the limits of open-source software

Public source code gives people an opportunity to review how the application works. It does not mean every build has been independently audited, nor does it guarantee that every security issue has already been found. Users handling sensitive information should follow normal device security practices.

Security verdict: LocalSend's local transfer model and documented HTTPS support are useful privacy features. The safest experience also depends on using trusted devices, maintaining updated software, and avoiding unnecessary access on untrusted networks.

LocalSend Transfer Speed: Is It Fast?

LocalSend can transfer files directly over a local network, but there is no single speed that applies to every device and setup. Network bandwidth, Wi-Fi signal quality, router performance, storage speed, file size, and device processing all affect the result.

We have not conducted controlled laboratory speed tests for this review, so we are not presenting invented transfer times or benchmark figures. The following scenarios show what to consider when evaluating LocalSend in everyday use.

Transfer scenario	What affects the result	What to check
Many photos from iPhone to Windows	Number of files, Wi-Fi quality, and destination storage	Compare the time for a small batch and a larger batch on the same network
Large videos from Android to Mac	Wireless link quality, file size, and disk write speed	Keep both devices close to the access point and avoid heavy network traffic
Hundreds of small files between computers	Per-file overhead, storage performance, and file count	Compare a folder transfer with a single large file of similar total size
Transfers over a phone hotspot	Hotspot implementation and whether connected devices can communicate	Confirm discovery works before sending a large file

For a fair comparison, use the same files and devices, keep the network conditions as consistent as possible, and repeat each transfer. Record the file size and elapsed time instead of relying on impressions from a single attempt.

If LocalSend feels slow, first check the Wi-Fi connection and whether other devices or downloads are using significant bandwidth. Moving closer to the router or switching to a less congested network may help. A wired Ethernet connection on a compatible computer can also improve consistency when the other device has a suitable network connection.

LocalSend Devices Not Showing Up? Try These Fixes

One of the most frustrating LocalSend problems is when both devices are open but neither appears in the destination list. This often points to local network discovery or firewall settings rather than a problem with the files themselves.

Problem	Possible cause	What to try
Devices do not appear	The devices are on separate networks or cannot communicate locally	Connect both to the same reachable local network and reopen LocalSend
Windows does not find a phone	Windows Firewall is blocking LocalSend	Allow LocalSend on the appropriate trusted private network profile
Devices connect to guest Wi-Fi	Guest network isolation prevents communication between clients	Use a trusted network that permits device-to-device communication
Discovery fails while a VPN is active	The VPN may block or redirect local network traffic	Review the VPN's local network settings and test on a trusted network
Devices appear, but transfers fail	Firewall rules, network changes, or application settings may interfere	Update LocalSend, restart the apps, and review local network permissions
Transfers stop when a phone is locked	Operating-system background restrictions may affect app activity	Keep the app open and the device awake during the transfer, then test again

Check Windows Firewall first

On Windows, confirm that LocalSend is allowed to communicate on the network profile you actually use. A firewall rule that permits traffic only on one profile may not help when Windows classifies the current connection differently.

Do not switch off all firewall protection as a permanent fix. If you need to create a rule manually, follow the official LocalSend documentation and limit the rule to the required traffic and trusted network.

Check router isolation settings

Some routers prevent wireless devices from communicating with one another. This feature may be called AP isolation, client isolation, or wireless isolation. Guest Wi-Fi networks commonly use similar restrictions.

If you control the router, check its documentation and confirm whether device-to-device communication is allowed on the network you are using. Do not change security settings on a network you do not manage.

Keep both devices available during a transfer

Mobile operating systems may limit background activity to save battery or manage resources. If a transfer repeatedly stops when the receiving phone is locked or LocalSend moves to the background, test again with the app open and the screen awake. Results can vary by operating system version and device settings.

For the latest troubleshooting guidance, consult the official LocalSend project repository and its documentation.

LocalSend Limitations You Should Know

LocalSend is useful, but it is not a universal replacement for every file-sharing method.

• Both devices need compatible software: Unlike AirDrop on supported Apple devices, LocalSend generally needs to be installed on each participating device.
• Network settings can interfere: Firewalls, isolated guest networks, and VPN configurations can prevent device discovery or transfers.
• It is not cloud storage: LocalSend moves files between devices. It is not designed to keep a cloud copy synchronized across all your devices.
• Mobile background behavior can vary: Operating-system restrictions may affect transfers when an app is not active.
• Transfer speed is not guaranteed: Actual performance depends on the network, hardware, storage, and file workload.
• Receiving files still requires care: Check the sender and destination before accepting files, particularly on shared networks.

Best LocalSend Alternatives

If LocalSend does not fit your workflow, several alternatives cover different file-sharing needs. The right choice depends on your devices and whether you need local transfers, ecosystem integration, or remote access.

Alternative	Best for	Main consideration
PairDrop	Browser-based sharing between devices	Browser and network behavior can affect the experience
KDE Connect	Connecting phones and computers for file sharing and device integration	Offers broader device interaction features beyond file transfers
Quick Share	Sharing files with compatible Android devices and supported computers	Compatibility depends on the operating system and supported hardware
AirDrop	Quick wireless sharing within Apple's ecosystem	Does not provide general native file sharing with Windows or Android

Choose PairDrop if you prefer a browser-based option and do not want to install a dedicated app for every transfer. Choose KDE Connect if you want file sharing alongside features that connect a phone and computer. Choose Quick Share if your devices are supported by Google's sharing system. Choose AirDrop if your devices are all compatible Apple products.
