BrowserPod is the API that turns any browser tab into a virtual Linux machine to run server-side processes client-side without cloud infrastructure. With its own client-side filesystem, syscalls and networking, it turns the browser into a sandboxed developer environment to run AI agents and the code they write. Developers can also transform their documentation spaces into interactive environments, building playgrounds where visitors can run full code snippets for free.

Because BrowserPod doesn't rely on cloud infrastructure, it is free for non-production use with 1,000 hours of free production use on the free plan, and only $0.01 per her of compute after.

JSFiddle features and specs

  • Easy Sharing and Collaboration
    JSFiddle allows users to share and collaborate on code snippets effortlessly by generating unique URLs for each project.
  • Real-Time Editing
    Changes made to HTML, CSS, and JavaScript are displayed in real-time, providing instant feedback and streamlining the development process.
  • Supports Multiple Frameworks
    JSFiddle supports various JavaScript frameworks and libraries such as jQuery, Vue.js, and React, allowing developers to experiment with different technologies.
  • Embed Feature
    Users can embed their fiddles directly into websites or blogs, enabling easy demonstration of code and concepts.
  • Version Control
    JSFiddle offers version control, allowing users to save different versions of their code and revert to previous versions if needed.

Possible disadvantages of JSFiddle

  • Limited Backend Support
    JSFiddle is primarily focused on frontend development and does not provide robust backend development capabilities.
  • Performance Issues
    With complex or resource-intensive projects, JSFiddle can experience performance lag, impacting the user experience.
  • Basic IDE Features
    Compared to full-fledged Integrated Development Environments (IDEs), JSFiddle lacks advanced features such as code linting, debugging tools, and extensive plugins.
  • File Management
    JSFiddle does not offer comprehensive file management, making it challenging to work on larger projects with multiple files.
  • Dependency Management
    Managing dependencies can be cumbersome, as JSFiddle does not provide built-in tools to handle package management seamlessly.

BrowserPod features and specs

  • Linux-Based
    BrowserPod is a lightweight Linux kernel that runs in the browser via WebAssembly.
  • File System
    BrowserPod provides a POSIX-like filesystem in the browser.
  • Portals
    BrowserPod's Portals feature listens for open ports and creates a shareable private link for instant, interactive demos of projects.
  • Multi-Language Support
    BrowserPod provides browser runtimes for Node.js, Python, Rust and Go.
  • Sandbox Environment
    BrowserPod inherits the security boundary of the browser, with additional security measures provided with controlled networking.
  • Latency Reduction
    BrowserPod provides zero latency boots, launching client-side and avoid roundtrip latency associated with cloud solutions.
  • Data Security
    BrowserPod runs on the user's device, meaning data doesn't leave their device, reducing the overall data surface.
  • Client-side computation
    BrowserPod utilizes client compute, leveraging user compute rather than provisioning expensive cloud compute.

Questions & Answers

As answered by people managing JSFiddle and BrowserPod.

How would you describe the primary audience of your product?

BrowserPod's answer:

We built BrowserPod for two major audiences. The first is developers who think about the economics of resourcing tools they create, both in terms of bare metal resource and unit cost. BrowserPod offers a solution to developers who want to make a development tool widely available, but don't want to pay to provision the cloud compute needed to scale its usage.

BrowserPod is scalable by design. Users commit their own device's resources to run the solution, rather than the developer having to provision additional resources from a cloud provider. Users' devices generally have more compute than they need to run their day-to-day workflows, so it makes sense for developers to leverage that idle resource, rather than create additional resource.

The second audience is major commercial solutions where unit cost really determines the viability of their business. For instance, any AI application that creates code needs a development environment with the tooling needed to write and run code. The solution most businesses reach for are cloud-based. But this is costly because there are real data centers that need to be paid for. BrowserPod doesn't provision any additional resources; it leverages existing compute on the user's device, massively cutting costs.

What makes your product unique?

BrowserPod's answer:

BrowserPod is the only API that turns the browser tab into a multi-runtime virtual machine, which means developers can create applications with server-side processes running directly in the browser.

Why should a person choose your product over its competitors?

BrowserPod's answer:

BrowserPod is more complementary than it is competitive with providers that sit in the same category. Cloud sandbox solutions like Daytona, Modal and E2B are brilliant, but have different use cases. BrowserPod is ultimately the solution you turn to when you want to take advantage of client-side computation at scale with unlimited concurrency, without having to pay for the additional cloud compute provisions required with alternatives.

WebContainers is an excellent peer of BrowserPod, but is no longer supported directly by StackBlitz. It's also missing important features, like multiple runtimes, a sophisticated filesystem and portal features.

Which are the primary technologies used for building your product?

BrowserPod's answer:

  • WebAssembly
  • Linux
  • BusyBox

What's the story behind your product?

BrowserPod's answer:

BrowserPod is built by Leaning Technologies, the team behind WebVM, CheerpJ and CheerpX. WebAssembly solutions with over one million users, that have been battle-tested by some of the world's biggest organizations. For years, Leaning Tech has provided free-to-use tools for developers and commercial solutions for businesses looking to modernize their technology stack.

With AI code generation becoming ubiquitous across software and the cost of cloud compute increasingly at a staggering rate, Leaning Technologies expertise with WebAssembly feels perfectly suited for a solution. BrowserPod is that solution.

Who are some of the biggest customers of your product?

BrowserPod's answer:

BrowserPod's built by Leaning Technologies whose customers include:

  • ADP
  • EDF
  • NASA
  • Siemens
  • TicketMaster
