Isolated environments.

Every branch is a full, disposable copy of your stack: its own server, database, and asset bucket. Agents experiment freely while production stays untouched until you merge.

Isolation by default

One branch. One world.

Every branch spins up a complete copy of your stack: its own server, its own database, its own asset bucket. Nothing is shared with production.

Agents experiment, migrate, and rewrite inside their own sealed environment. Your live site never feels a thing.

Nothing shared

Isolated down to the last byte.

Each environment gets its own copy of everything that makes your site run. Nothing leaks, nothing collides.

Dedicated server

A live instance of your site per environment. Preview exactly what will ship, in real conditions.

Isolated database

A full copy of your data. Migrate, seed, and rewrite with zero risk to production.

Separate media library

Its own asset bucket. Generated images and uploads stay contained until merge.

Sandboxed agents

Each agent works inside its own environment. It can break things there, never in yours.

Fast and parallel

Created in milliseconds.

Disposable by design: spin one up per task, per agent, per idea. Throw it away when the work ships.

Instant by default

A complete environment in less time than a page refresh. No queue, no build step to wait for.

Dozens in parallel

Every agent gets its own world. Run ten changes at once: work never collides, reviews never block each other.

Preview, then production

Review for real. Merge once.

A merge technology built for whole websites: code, schema, content, and labels travel together from the preview environment into production.

01

Open the preview

A real, running copy of your site on its own URL. What you see is what will ship.

Merge to production

Approve it yourself, or let your rules merge it. You define them when configuring the agent.

Approve and merge
Why this model

Branches, preview environments, reviews, merges: the workflow developers have trusted for decades, made accessible to marketing teams. Agents keep their power and autonomy. Humans keep control.

FAQ

Questions about environments.

A full, disposable copy of your website: its own server, database, and asset bucket. You review changes there for real before they merge. On Fimo, every branch gets one automatically, ready in milliseconds.
Yes. An agent experimenting in production is a risk you do not need to take. Every Fimo agent works in its own sandbox with a dedicated server, database, and media library, so it can try anything while production stays sealed until you merge.
Yes. Isolation goes down to the data layer. Content edits, schema changes, and agent experiments run against the branch database, never against production data. Delete the branch and the environment goes with it.
Milliseconds. The environment exists as soon as the branch does, so neither agents nor teammates ever queue for staging. Run as many in parallel as you have branches.
Staging is one queue the whole team fights over, and one broken experiment blocks everyone. Here every branch and every agent gets its own copy of the stack, so work runs in parallel and every review shows exactly what will ship.
