Know If Your Node.js Project Is Bun-Ready
Scan your codebase in seconds — not weeks. BunReady analyzes every dependency, native addon, and Node API call to give you a clear migration confidence score before you commit to switching runtimes.
Everything you need to get started
Built for developers who value speed, reliability, and simplicity.
Instant Compatibility Score
Paste your package.json or connect your repo. Get a 0–100 Bun compatibility score in under 30 seconds — no installs, no config, no guesswork.
Deep Dependency Analysis
BunReady cross-references every npm dependency against known Bun compatibility data. See exactly which packages work, which need alternatives, and which block your migration.
Native Addon Detection
Native C++ addons are the #1 migration killer. BunReady flags every native module in your dependency tree and suggests Bun-native replacements where available.
Node API Coverage Map
Not every Node.js API is supported in Bun yet. Get a line-by-line report of which Node APIs your code uses and whether Bun covers them — zero surprises on deploy day.
CI/CD Migration Guard
Add BunReady to your pipeline and catch compatibility regressions before they hit production. Get Slack and GitHub alerts when new dependencies break Bun support.
Team Migration Dashboard
Track Bun readiness across every repo in your org. Prioritize migrations by impact, see progress over time, and give engineering leads one source of truth.

We were about to spend two sprints on a Bun migration with no idea if it would work. BunReady flagged 3 blocking native addons in 20 seconds. Saved us weeks.

Staff Engineer
The CI/CD integration is a game-changer. Every PR now shows a Bun readiness delta so we know exactly when we're ready to flip the switch.
Marcus Rivera
Engineering Lead
I ran BunReady on 40+ repos across our org. Within a day we had a prioritized migration plan. Management finally approved the switch.
