Introducing Marble

Offchain software powers nearly every user interaction in crypto. These systems – indexers, traditional web servers, bots, and more – are just as important as smart contracts for modern crypto applications.

As the creators of Ponder, an open-source indexing framework, we work with hundreds of developers at this layer of the stack. Engineering teams often spend months struggling with unreliable RPCs, reorgs, and backfills – and still end up with a system that’s slow and difficult to maintain.

In our view, the difficulty of developing offchain software is one of the most under-appreciated problems in crypto. It’s so painful that developers typically settle for less ambitious products than they envisioned.

Our path so far

Ponder has grown tremendously since our first release 18 months ago. Today, hundreds of companies and projects – including Morpho, ENS, and Optimism – use our open-source framework to power websites, mobile apps, and backend services with custom indexed data at scale.

But, things aren’t perfect. Many of our users struggle to self-host Ponder in production – it’s difficult to avoid downtime during redeployments, backfills complicate resource sizing, and observability requires additional setup. Some Ponder users have the infrastructure experience necessary to solve these problems, but most developers want something that just works.

Marble

This is why we are launching Marble. Alongside Ponder’s local development experience, we now have a production workflow that’s fast, intuitive, and accessible to any developer.

With Marble, developers can deploy any Ponder project to production in a few clicks, with zero-downtime deployments, built-in RPC connections, automatic observability, collaboration tools, and much more. Several teams are already using Marble in production, including Whetstone and Plume.

Marble

Our approach

We want to help ambitious developers build fast, reliable, and fully custom software that interacts with blockchains.

Indexing is our first focus (it’s foundational), but we'll soon apply the same approach – primitives for custom code, not one-size-fits-all solutions – to other categories of offchain software.

We’re committed to open-source. Ponder, the core engine of our offering, will remain open-source, easy to self-host, and permissively licensed.

Get started

We’re inviting more developers to get started on Marble each week – request access here and follow us on X and Farcaster to stay in the loop.

Join our team. We’re hiring engineers and designers to work with us at our office in New York City.
