Restbed Unix Build Status Windows Build Status

Restbed is a comprehensive and consistent programming model for building applications that require seamless and secure communication over HTTP, with the ability to model a range of business processes, designed to target mobile, tablet, desktop and embedded production environments.

It's akin to embedding NGINX into your companies own product line. -- Solutions Architect, Bellrock Technology


Feature Description
WebSockets Full-duplex communication channels over a single TCP connection.
Server-Sent Events Server-Sent Events enables efficient server-to-client streaming of text-based event data—e.g., real-time notifications or updates generated on the server.
Comet Long polling model to allow long-held HTTP requests for pushing data from the server to client.
SSL/TLS Secure over the wire communication allowing you to transmit private data online.
Session Management Create custom HTTP session persistence and management logic.
HTTP Pipelining A technique allowing multiple HTTP requests to be sent on a single TCP connection without waiting for the corresponding responses.
Path Parameters Annotate URIs with custom path parameters such as resource keys, revisions, etc...
Query Parameters Automated query parameter parsing.
Header Filters Filter incoming HTTP requests by headers.
Logging Customise how and where log entries are created.
Multi-Path Resources Give a resource multiple paths for improved readability.
Customisable Methods Add your own custom HTTP methods.
Compression Adaptability to address any form of compression GZip, Deflate, etc...
Encoding Adaptability to address any form of encoding UTF-32, ASCII, etc...
Rules Engine Reduce complexity by processing incoming requests with readable units of code.
HTTP/HTTPS Built in client capabilities with optional SSL peer certificate verification. Deprecated
IPv4/IPv6 Internet Protocol Version 4/6 Network Support.
Architecture Asynchronous single or multi-threaded architecture, capable of addressing the C10K problem.
Converters Built-in Path, Query, and Header conversions for primary data-types.
Authentication Separate Service and/or Resource level authentication.
Error Handling Separate Service and/or Resource level error handling.
Address Binding Bind HTTP and/or HTTPS services to separate IP addresses.
Signal Handling Capture OS generated process signals.
Documentation High-quality documentation covering the architecture and API.
Compliance Flexibility to address HTTP 1.0/1.1+ compliance.
Mature Secure, Stable, and extensively tested since 2013.
Community Active, vibrant and energetic open source community.
Support Commercial support is available from Corvusoft.

    settings->set_port( 1984 );

    Service service;
    service.publish( resource );
    service.start( settings );

    return EXIT_SUCCESS;

git clone --recursive
mkdir restbed/build
cd restbed/build
make install
make test

You will now find all required components installed in the distribution sub-folder.

Building with external libraries

If you wish to build with external libraries (OpenSSL, ASIO).

git clone
mkdir restbed/build
cd restbed/build
make install
make test

Windows Build Instructions

For Microsoft Visual Studio instructions please see feature #17.

Building restbed - Using vcpkg

You can download and install restbed using the vcpkg dependency manager:

git clone
cd vcpkg
./vcpkg integrate install
./vcpkg install restbed

The restbed port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please create an issue or pull request on the vcpkg repository.


This codebase is intended to be as self documenting as possible. We have supplied many examples and test suites to help aid developers.

You can locate the latest design and API documentation here.
