Migration Playbook: Switching Without Friction
Swapping a daily driver mid-project is costly. Follow this three-step checklist to evaluate Bolt.new and Lovable on equal terms before standardizing your team.
Export Config, Prompts & Data
Inventory what each candidate needs: prompt libraries, templates, connected accounts and project files. Export from your current stack first so Bolt.new and Lovable start from the same baseline.
Map Pricing to Your Real Usage
Compare published entry tiers against your expected volume. Bolt.new starts at $25/mo (freemium); Lovable starts at $25/mo (freemium) — model the monthly cost at your actual workload before committing.
Run a Two-Week Parallel Trial
Run both tools on the same live tasks for ten working days. Score outputs against the five Airecmark dimensions, then let the 0.4-point composite gap — not vendor marketing — decide the standardization call.
Deterministic Evaluation Methodology & Integrity Standard
AiRecMark evaluates every tool against its deterministic five-dimension index (Quality, Features, Usability, Performance, Value) using official documentation, published pricing pages and the published five-dimension rubric. All scores, deltas and winner calls in this dossier are drawn from the published tool archives as of 2026-09-06 and can be traced back to the public tool profiles.
