For over a decade, we relied on Meteor.js to power our applications, and it was instrumental in helping us build and scale products quickly. Meteor.js introduced us to the magic of real-time updates, a unified JavaScript stack, and developer-friendly tools that made full-stack development remarkably seamless. However, as our projects and teams grew, we began encountering limitations that made us question whether Meteor was keeping up with the demands of modern web development.
At our previous startup, we pushed Meteor to its limits, and while we loved what it offered, there were pain points we couldn't ignore. Scaling real-time apps efficiently became a struggle with the pub/sub system's limitations, to the point that we had to switch almost everything to regular methods without live updates. Observability in production was challenging, and we mostly had to hack together solutions to monitor and debug our applications - writing our own custom CPU & Memory profiling connectors for Node.js, custom MongoDB query profilers, method call tracing (the existing Meteor APM was not complete enough to debug production crashes). It was clear to us that while Meteor was once cutting-edge, the world of web development along with our product had evolved, and the tools we relied on hadn't evolved with it.
That's why we built Modelence - a modern full-stack framework born out of our direct experience with Meteor, our deep understanding of its strengths and weaknesses, and engineering challenges not specific to our product that we had to solve, added to it. Modelence is not just a framework - it's the whole platform we wish we had during those years. It preserves the best parts of Meteor - the simplicity, developer experience, and rapid prototyping - while addressing the challenges we faced, such as scalability, flexibility, and production readiness.
What we loved the most about Meteor:
- Be able to easily deploy to Meteor Cloud (aka Galaxy). This saved us tons of DevOps time during the first few years.
- Built-in real-time data synchronization (great to start with, although problematic later on)
- Full-stack setup with an easy build setup to seamlessly connect front-end and back-end
What we struggled with:
Scaling Real-Time Applications
As our application grew, scaling became a significant challenge. The inefficiency of Meteor's pub/sub architecture made it hard to scale efficiently under heavy loads. Maintaining real-time connections for thousands of users often led to performance bottlenecks, requiring workarounds like manually managing subscriptions or offloading data to non-real-time channels.
Tooling Choice
Meteor introduced its own build system and frontend framework (Blaze), but it had a pretty tough timing because all these tools got replaced later on (Vite / Webpack / Turbopack for build and React for frontend).
Limited Observability and Production Readiness
In production, we often struggled to monitor and debug our applications effectively. Meteor lacked built-in support for advanced tooling to help debug crashed containers, identify MongoDB queries that fetch too much data or create too much load. Setting up observability tools meant stitching together third-party solutions, which added complexity and still didn't fully solve all cases - for example if we wanted to make sure that we get all latest logs and traces from crashed containers which were automatically being shut down by Meteor Cloud without providing enough information to debug.
Community Stagnation
Meteor's early momentum made it a strong choice for many developers. However, in recent years, its ecosystem has slowed down. Fewer updates, shrinking community resources, and less support for modern use cases created challenges for us to stay up-to-date and future-proof our applications (most of the core Meteor team has moved on to work on Apollo GraphQL). This made us increasingly concerned about the long-term viability of Meteor, especially seeing no meaningful changes, features or improvements in Meteor Cloud for years.
We wanted a framework that retained the ease and speed of development we loved in Meteor while solving the pain points that made it hard to scale and innovate.
Our goal with Modelence was simple: build a developer-friendly framework that scales well and solves all standard challenges that are common in most applications. Modelence evolves Meteor's simplicity and focus on real-time apps to meet the demands of modern web development.
Built-in Scalability
- Built-in support for distributed cron jobs ensures background tasks can run with precision, without conflicts and without affecting your application containers.
- Modelence's real-time features use WebSockets based on MongoDB Change Streams, but also allows you to customize your live data to scale further with a messaging queue, without relying on a database.
Modern Tooling
- Built-in MongoDB allows you to store and retrieve data without having to worry about setting up a database or connecting to it manually.
- Native TypeScript support provides type safety without additional configuration.
- Vite ensures blazing-fast builds, even for large applications. At the same time, you can also easily add Modelence to an existing Next.js project.
Production-Ready Out of the Box
- Modelence Cloud integrates seamlessly with modern AWS services.
- Advanced error tracking and monitoring ensure you can debug and resolve issues quickly.
- Built-in logging and observability tools give you deep insights into your app's performance and behavior.
Modelence Dashboard
- Seamless setup for local dev environments utilizing all the same admin dashboards, without the need to run MongoDB locally.
- A built-in admin dashboard to manage your deployment, application configuration and credentials, cron jobs, browse your data & data models.
