Should I upgrade to Qwik 2 Adoption now?

Decide whether to upgrade to Qwik 2 now or wait until plugin and deployment integrations catch up with the new routing and rendering assumptions.

Wait on Qwik 2 unless you can pilot it on a custom integration stack and verify routing, SSG, and deployment end to end.

Wait on Qwik 2 and keep production apps on Qwik 1.19.2 plus Qwik City

As of 2026-04-05, the official GitHub releases page shows the stable framework line at "@builder.io/qwik@1.19.2", while the Qwik 2 line is still published as pre-release packages such as "@qwik.dev/core@2.0.0-beta.29" and "@qwik.dev/router@2.0.0-beta.29". The official routing and deployment docs still describe the current production model in Qwik City terms, including file-based routing under "src/routes" and adapters imported from "@builder.io/qwik-city/adapters/..." with commands like "qwik add static" and "qwik add express". Official docs pages carry an MIT License footer, so the blocker is not framework licensing but migration and integration churn. Given those official facts, the safest default is to stay on the stable 1.x line until the Qwik 2 package names, router shape, and deployment story are documented as the mainline path.

When to choose

Best for "small-team" plus "low-ops" teams, especially when production deploys depend on existing Qwik City adapters or third-party tooling that expects "@builder.io/qwik" and "@builder.io/qwik-city". Choose this when upgrade risk is dominated by routing, SSG, or deployment integration compatibility rather than by raw framework performance.

Tradeoffs

Lowest migration risk and the clearest official deployment guidance today. The tradeoff is delaying Qwik 2 runtime and router changes, so you accept another migration later.

Cautions

Qwik 2 is not just a patch upgrade: the official pre-release line uses different package names and a different router package, so do not assume plugins, starter templates, or internal scripts will keep working unchanged.

Adopt Qwik 2 beta only for a controlled pilot or custom integration stack

As of 2026-04-05, the official pre-release line is Qwik 2 beta, with packages such as "@qwik.dev/core@2.0.0-beta.29" and "@qwik.dev/router@2.0.0-beta.29" on the official releases page. The Qwik team's "Towards Qwik 2.0" post says v2 changes the rendering model by moving virtual-node data to a "<script type=\"qwik/vnode\">" block at the end of HTML and making resuming lazier. The router beta release notes also document breaking routing changes: the route configuration object changed to a more efficient trie structure, it no longer includes "menus", a new unified "routeConfig" export was added, and SSG now runs in a separate process using Workers. That makes Qwik 2 reasonable only when you own the build, routing, and deploy layers closely enough to absorb those changes directly.

When to choose

Best for teams that can tolerate pre-release risk and do not depend on turnkey adapter support. Choose this only when you want early access to the new rendering and router model and can validate your own deployment pipeline end to end.

Tradeoffs

You get earlier exposure to Qwik 2's runtime and router direction. The cost is higher migration effort, pre-release instability, and more work on package-name, route-config, and SSG-process assumptions.

Cautions

Do not treat the current beta as a drop-in replacement for Qwik City 1.x. The official sources show package renames and router/SSG behavior changes, so any plugin or deployment integration that assumes the old import paths or route config shape needs explicit validation.
