Soffi vs.
AI coding tools
Soffi is for you if
You stop your work to load a PR, then leave feedback somewhere else.
A 30-second change costs two hoursof your engineering team's focus.
You set up local dev for someone who'll use it twice and now you're their IT.
You'd have to learn an IDE to change your own product.
What you can't do with just an IDE or cloud agents
Why not just use Cursor, Claude Code, or our own cloud agents?
- Open any PR as a running instance of your product.Not a diff, not a screenshot. The app in a browser.
- Let a designer or PM ship a change without an engineer.Not a request, not a ticket. A PR you merge.
- Put three people on the same running screen at once.Cursors, comments, and video on live product.
- Change backend logic, not just the UI.Full monorepo, with logs and console errors in scope.
- Find where your code drifts from your system, then fix it.Your real tokens and components.
- Hand an exec or a customer a link to unmerged work.Comment-only access, no setup or install.
The Landscape
“Why not just use Cursor, Claude Code, or our own cloud agents?”
| Soffi | In the IDE (Cursor, Copilot) | Delegated to an agent (Claude Code, Codex) | Wired together in-house | |
|---|---|---|---|---|
| Who does this | Just us :) | Cursor, Claude Code, Copilot | A ticket assigned to a cloud agent | Webhooks and scripts you maintain |
| What it is | A collaborative deployment environment that runs on your app | Editor tooling for people who write code | Ticket in, diff out | Glue you own forever |
| Who can use it, and what they need | The whole team, with a browser | Whoever has a terminal and the repo running locally | Anyone who can write a precise ticket | Whoever built it |
| Your product running, without local dev | We build and run it from your repo, front end and backend | You run it on your laptop | someone still runs the branch to review it | yours to build and keep alive |
| Checked before it reaches you | Lint with self-healing auto-fix, typecheck, and design-system compliance on every patch | sometimes runs your tests | Depends on what you built | |
| Multi-player | Cursors, comments, video, watch mode, and every change versioned by user, including prompts | |||
| A non-engineer can produce a mergeable PR | A designer or PM, unassisted | if they can write a precise enough ticket | ||
| A stakeholder can open a preview and comment | An authenticated live URL, not a secret link | You can see it on localhost, but sharing needs a preview system you build | a vendor link | Depends on what you built |
| What you end up with | A PR with a live preview to review | A diff on someone's machine | A PR you have to pull down | Whatever you built |
| The agent sees your app running, not just the files | Rendered UI, logs, console errors | files only | files only | |
| Design system grounding | We extract your design system and usage patterns from your codebase automatically | files in context | ticket text plus repo access | docs you maintain, and they go stale |
| Time to a real change in the product | Minutes | Fast, for whoever has the terminal | One round trip per iteration | Months to build, then it depends |

Coexist
Your engineers stay where they are. Same branch, same PR, same review.
Linear and Jira stay where work is tracked. Soffi can build directly from a ticket, and it's still where the work lives.
Your designers keep it. Attach the files and Soffi reads the real component values.
What we've heard
"One designer will take it off of our GitHub, put it on their local environment, tweak things. Then another designer wants to collaborate with them, so they'll have to download their repo, then branch it out. It's really painful because it's very static versions."
"Everyone's fairly technical here, so we have that going for us. But, the handoffs are still rough. It's like, okay, pull this PR environment. And, you have to stop what you're doing."
"It's like a 30 second change that costs two hours of their focus. Is it worth interrupting somebody's more valuable sprint work, asking them to stash their changes, create a new branch, create a PR, go through all the things just to fix this in the UI?"
"We wait a week to ship a one-line copy change."
Common questions
No. Soffi is a development environment. We host your app from your repo, your team edits the running product, and the work leaves as a pull request. For designers, it solves the last 20%. Prompting gets you close, then color, type size, spacing, and layout order you adjust by hand. That's the control an IDE can't give you. Soffi isn't a canvas, and it won't replace Figma.
Some can. Most can't, because it assumes a terminal, a cloned repo, and a local environment that runs. Output is a diff, so they can't tell whether the change works. Your engineers can keep their tools on the same branches and review.
No. Each change gets its own isolated environment with its own database built from your repo and torn down when the PR closes. There's no long-lived environment holding state, and it isn't on your infrastructure or in your on-call rotation.
It isn't generating into a blank canvas. Ask for a red button and it uses your existing token instead of inventing one. Deprecate a token and it stops using it, including when someone prompts. Every change is a diff you can read line by line and revert.
Nothing merges without your review. Every change is a branch that becomes a PR in your normal pipeline, with your CI, your tests, and your approvers. We run lint and type-checks before the PR even exists, and you're working on seed data in an isolated environment, never production.
Install your GitHub app and give us a few environment variables. We build the containers, discover your services, seed a database, deploy a running instance, and read your architecture and design system. One engineer connects it once and everyone else is one click from the running product. Same-day on a modern stack, and we're white-glove through the beta.
JavaScript, TypeScript, and React with backend logic and monorepos supported. Web today, including mobile web and editing across breakpoints. Very legacy apps and API-only products aren't a fit, and we'll tell you that rather than waste your time.
