Tilt
Developer Tools
Local Kubernetes development loop that rebuilds and live-updates containers on save

The short version
- Each has a real cost: Rollup slower than the Go and Rust bundlers that followed it, since it is written in JavaScript; Tilt docker acquired Tilt in 2022 and the team now splits its time across Compose and Docker Desktop, so feature velocity is modest and the product's long-term priority inside Docker is not guaranteed; treat it as a stable utility, not a growing platform.
- They diverge on capability: Rollup covers Tree shaking, Tilt covers Live update.
- Prices and features above were last checked on 31 August 2026.
Where they differ
Only the attributes on which Rollup and Tilt actually diverge.
Identical on both: starting price (Free), pricing model (Open source, no licence fee), free tier (Yes), platforms (Linux, macOS, Windows), user rating (Not yet rated).

What people use each for
The jobs each tool is most often brought in to do.
Rollup
- Publishing a JavaScript library in several module formatsnot Tilt
- Builds where output size and cleanliness matter more than build speednot Tilt
- Producing ES module output for consumers who will bundle it themselvesnot Tilt
Tilt
- A team of ten or more engineers whose application is fifteen microservices on Kubernetes and who currently wait on CI to test a changenot Rollup
- An organisation onboarding new developers who want a single command that stands up the whole stack from a committed Tiltfilenot Rollup
- A platform team giving product engineers a consistent local environment against a shared remote development clusternot Rollup
- A codebase where one repository contains several services and rebuilding all of them on every edit is the main source of lost timenot Rollup
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Rollup
- Slower than the Go and Rust bundlers that followed it, since it is written in JavaScript
- Application concerns like dev servers and hot reloading are not its job, so app builds need Vite on top
- Configuration for non-trivial applications gets verbose compared with tools that assume more
Tilt
- Docker acquired Tilt in 2022 and the team now splits its time across Compose and Docker Desktop, so feature velocity is modest and the product's long-term priority inside Docker is not guaranteed; treat it as a stable utility, not a growing platform.
- The Tiltfile is Starlark, a Python dialect, so non-trivial setups become real programs that need reviewing and maintaining, and the person who wrote yours becomes a single point of failure.
- Live update only works when the running container can accept synced files and restart the process; compiled languages, distroless images and read-only filesystems often force you back to a full image rebuild, which removes the main benefit.
- It assumes Kubernetes. If your development target is plain Docker Compose or serverless functions, Tilt adds a cluster you did not need and a layer of abstraction with no payoff.
- There is no commercial support contract, no SLA and no paid tier, so when a Kubernetes version upgrade breaks something you are dependent on GitHub issues and a Slack channel rather than a vendor you can escalate to.

Questions people ask
- Is Rollup or Tilt better?
- Neither clearly leads. Rollup starts at Free and Tilt at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Rollup or Tilt?
- Rollup starts at Free and Tilt at Free.
- Does Rollup or Tilt run on more platforms?
- Both run on Linux, macOS, Windows, so platform support will not decide this one for you.
- Can I use Rollup for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Rollup best used for?
- Rollup is most often used for publishing a javascript library in several module formats, builds where output size and cleanliness matter more than build speed, producing es module output for consumers who will bundle it themselves. Of those, publishing a javascript library in several module formats and builds where output size and cleanliness matter more than build speed are not what Tilt is typically brought in for.
- What can Rollup do that Tilt cannot?
- Rollup covers Tree shaking, Clean output, Multiple output formats, Plugin API. Tilt covers Live update, Tiltfile as code, Unified web UI, Selective rebuilds.
Answered from the vendors’ own pages
Rollup: Is Rollup free?
Yes, open source under the MIT licence.
Tilt: Is Tilt free?
Yes, entirely. It is Apache 2.0 open source with no paid tier and no licence fee.
Rollup: Rollup or webpack?
Rollup is the usual choice for libraries thanks to cleaner output and better tree shaking. webpack remains stronger for complex applications with heavy asset handling.
Tilt: Who owns Tilt now?
Docker, which acquired it in May 2022. It remains open source and the repository is still actively maintained.
Rollup: Do I need Rollup if I use Vite?
Not directly. Vite uses Rollup for production builds, so you already benefit from it.
Tilt: Do I need a remote cluster?
No. It works against a local cluster such as kind, minikube or Docker Desktop, and also against a shared remote development cluster if your services are too heavy to run locally.
Tilt: How is it different from Skaffold?
Both automate the build-deploy loop. Tilt puts more weight on the live-update path and a multi-service dashboard; Skaffold is more configuration-driven and closer to Google's tooling.
