AI Builders From Lovable & Bolt to KERNSTACK AI builds. Engineers own. Keep your generated frontend and move the backend into stack.json. Migrate from AWS Migrate from AWS to KERNSTACK Migrate from AWS to KERNSTACK: re-declare Lambda, DynamoDB, and S3 as one stack.json project in Europe. Real mapping, order, and effort. Migrate from Cloudflare Migrate from Cloudflare to KERNSTACK Migrate from Cloudflare to KERNSTACK: Workers to nodejs workers, D1 and KV to tables, R2 to buckets. What has no equivalent, stated plainly. Migrate from Firebase Migrate from Firebase to KERNSTACK Migrate from Firebase to KERNSTACK: Firestore to keyed tables, Cloud Functions to nodejs workers, Hosting to gateway routes. Exit guide. Migrate from Heroku Migrate from Heroku to KERNSTACK Migrate from Heroku to KERNSTACK: dynos and Procfiles to declared workers and workflows, Postgres add-ons to tables, config vars to secrets. Migrate from Lovable Migrate from Lovable to KERNSTACK Migrate from Lovable to KERNSTACK: export the generated code, re-declare its hosted backend in stack.json, and run it as your own project. Migrate from n8n Migrate from n8n to KERNSTACK Migrate from n8n to KERNSTACK workflows: turn product-facing automations into declared function, worker, and human steps in stack.json. Migrate from Pinecone Migrate from Pinecone to KERNSTACK Migrate from Pinecone to KERNSTACK: rebuild vector indexes over your own tables and buckets, re-embed from source, drop the second vendor. Migrate from Supabase Migrate from Supabase to KERNSTACK Migrate from Supabase to KERNSTACK: export Postgres to keyed tables, storage to buckets, Edge Functions to workers. Honest SQL trade-offs. Migrate from Vercel Migrate from Vercel to KERNSTACK Migrate from Vercel to KERNSTACK: keep the frontend, re-declare functions, data, and cron as one stack.json project. Mapping and order inside.
FAQ

Frequently asked questions

No. Your existing frontend builds in apps[], and your existing Go, Node.js, Python, or PHP code runs in Functions and Workers. What changes is that infrastructure state moves out of vendor dashboards and into a single reviewable stack.json.

Yes. Agents in KERNSTACK sandboxes or Cursor inspect your existing repository, generate the stack.json resource declarations, and preview the deployment diff with kernstack plan.

Deploy the stack to an isolated KERNSTACK staging or parallel production environment, seed or sync tables and buckets, verify on the preview route, and then switch the custom domain.

Compare · AWSKERNSTACK vs AWSAWS gives you every service separately. KERNSTACK declares the common ones — compute, data, search, workflows — in one European project.Compare · CloudflareKERNSTACK vs CloudflareCloudflare spreads an app across edge products. KERNSTACK runs one project — compute, data, search, workflows — in a single European zone.Compare · FirebaseKERNSTACK vs FirebaseFirebase wires your app into Google services. KERNSTACK declares that backend — compute, data, files, workflows — as your own European project.Compare · HerokuKERNSTACK vs HerokuHeroku made git-push deploys famous. KERNSTACK keeps that calm and adds data, search, and agents as resources, not separately billed add-ons.Compare · LovableKERNSTACK vs LovableLovable prompts an app into existence. KERNSTACK is where such an app gets declared, reviewed, and operated as a real project in Europe.Compare · n8nKERNSTACK vs n8nn8n connects tools with visual automations. KERNSTACK workflows run inside your product — function, worker, and human steps in stack.json.
