Where Morph Apply Fits
App builders need predictable merges, not flaky patching. Morph Apply keeps the codebase coherent while the agent iterates.
Multi‑File Reliability
Apply changes across UI, API, and data layers in one pass without breaking imports or types.
Sandbox‑First Flow
Run changes in E2B, Fly.io machines, or containers before they touch production.
Reviewable Output
Return merged files and show diffs in your UI before applying.
Minimal Apply Payload
Keep the apply step explicit. The LLM generates the update snippet, Morph Apply merges it into your actual code.
Instruction + Code + Update
<instruction>Add pagination to the users list</instruction>
export async function getUsers() {
return db.user.findMany();
}Guardrails That Keep Builders Stable
Don’t let edits write straight to prod. Keep the loop tight and safe.
Recommended Safety Loop
- Run Morph Apply inside a sandboxed workspace.
- Show a preview diff before writing files.
- Execute tests or typechecks automatically.
- Only publish the final merged output.
