What is Osgood?
Today we build web applications with general purpose language runtimes. Osgood is an experiment that asks the question: "What if we built a runtime specifically for web apps? What kind of benefits can we get from being at a higher level of abstraction?"
Since the Osgood runtime has intimate knowledge of the routing table we get the ability to isolate controllers for free (we refer to these as Workers). The I/O performed by the application, as well as policy enforcement, happens in Rust-land. Each worker has its own set of permissions.
Here's an example policy:
Consider the situation where Controller A has permission to send a message to
intrinsic.com, and Controller B has access to user credentials. Within a properly configured Osgood application this means it's not possible to transmit user credentials to

An Osgood application file is essentially the entrypoint for the application. Each application will have a single application file. It is the only necessary argument for the
This file has three purposes:
- Configure global settings such as port and interface
- Route incoming requests to the desired Osgood worker
- Configure the security policies for each Osgood worker
More information about Osgood application files are available on the Osgood Application File wiki page.
An Osgood worker file works by exporting a default function. Typically you'll export an
async function but it also works fine by returning a promise or a string value.
Workers are called with information about the incoming request and the returned value is then used to dictate the response to the client.
More information about Osgood worker files are available on the Osgood Worker Files wiki page.
