Is Bun worth running as a client service?

Bun's Level 1 evidence supports a low-setup, hours-to-value managed service around Node.js migration, bundling, testing, and profiling, with strong performance and compatibility momentum. What remains unknown is vendor pricing (Bun is open-source with no published tiers), client fees, agency labor cost, and therefore any ROI or margin claim.

An agency-fit judgement for reselling this service. It is separate from the tool description on the decision record.
