The platform

A lightweight engineering harness you can trust

Every change runs in its own isolated, secure environment and lands as a PR your team can review. Built from your components and design system, so you get code you'd actually merge.

You keep control. We keep it running

How it works

Soffi is collaborative staging infrastructure between your coding agents and main. We run a live, isolated copy of your product for every change, and everything comes back to your team as a PR.

Learn how Soffi works

Nothing to set up or maintain

Soffi runs the environments, data, and context around your code. Nothing to run locally, and your stack gets better for it.

Environments on demand. An isolated, running copy of your app for every PR and workspace. No clusters, no preview infrastructure, nothing on your on-call.
A backend that mirrors yours. We create a data twin of your APIs, auth, and data shapes, so you can stage on your real app with realistic data, all without touching production.
Your GitHub and CI, upgraded. Every change still lands as a normal PR, now with a live preview and written context your reviewers can act on.
Your coding agents, better informed. Agents get your codebase context, precise backend specs, and tasks to pick up, instead of a vague ticket.

Review working software, not walls of diff

AI made code cheap and review expensive. Every Soffi PR is interactive, visual, and always up to date.

A live preview, not just a diff. Open the PR in your running product, click through it, and jump from any change to the code behind it.
The context is written for you. A plain-English summary, before/after images, and backend requirements on every PR.
Kept current on every push. The description, images, and requirements update as the PR changes, with a view of what changed since you last looked.
Fix it instead of commenting on it. Reviewers can leave comments or video on the exact element, or make the change and push it back to the same PR.

Quality that compounds

Code built to your standards, in PRs that need less cleanup.

Built from your code. Changes use the architecture, components, tokens, and patterns your team already wrote.
One consistent design system. Soffi finds hardcoded values, inconsistent patterns, and deprecated components, and fixes them at the source.
Checked before it's a PR. Soffi lints, typechecks, and runs the app to confirm the change works. A person confirms every push.
A better baseline for every tool. A cleaner codebase means better output from everything your team uses, including the agents on their own machines.

Nothing touches production. Nothing merges without you

Every environment is isolated and secure, and your engineers decide what merges.

Isolated by default. Every environment is walled off from other customers and from Soffi's internal systems.
Nothing from production. No production data, database access, or backend credentials. Third-party services like payments or an LLM only connect if you add a key.
Access you control. Scoped to the repos you pick and revocable anytime. Previews are private to the people you invite.
A person in every loop. Someone on your team confirms every push, and your engineers always merge.

Why not build it yourself

Soffi gives you an isolated copy of your app for every change, an agent that knows your codebase, and an editor anyone can use. Building that yourself means new infrastructure and a team to maintain it forever.

What each capability takes to build yourself, against what Soffi provides
What it takes	Building it yourself	With Soffi
Isolated environments	Isolated environments for every PR, orchestration, networking, and a backend that works without production, secured and paid for even when idle	Hosted environments with a data twin, asleep when idle
Codebase context and checks	Codebase context, guardrails, checks, and review summaries, rebuilt every time your stack or agents change	Generated from your repo and kept up to date, checked before every PR
Editing the running product	An editor that maps clicks on your running UI back to your code, plus comments and video	Comments, video, and edits on the running product

Common questions

01Why not just use Claude, Cursor, or build it yourself?

Keep using them. Claude and Cursor write the code. Soffi is everything around it: a live, isolated copy of your app to run it in, a data twin instead of production, checks before it's a PR, and one place where PMs, designers, and engineers review it together.

Your agents also get codebase context and backend specs from Soffi, so their output gets better too.

02How do I know this won't add AI slop to our codebase?

Soffi builds with the components and patterns your team already wrote, checks its work before a PR exists, and never merges. Your review process decides what ships.

03So PMs and designers ship straight to prod?

No. Their change opens as a PR into your existing review. You approve and merge.

04Do you need our production data, database, or backend credentials?

No. The data twin stands in for your backend. The only keys you might add are for third-party services you want working live in Soffi.

05Does this replace our CI or code review?

No. Soffi adds a live preview and context to the PRs your team already reviews. Your CI, checks, and approvers stay the same.

06Is this another tool to maintain?

No. Soffi hosts and runs every environment and keeps it in sync with your repo. Nothing to stand up, and nothing enters your on-call rotation.
