Phion.dev
Versioned Cursor rules management with backup, rollback, and one-click publishing for Cursor users.
Phion solves a real, narrow problem: Cursor rule sprawl. If your team is Cursor-only and rules are drifting, versioned rules plus rollback, conflict detection, and one-click publishing is genuinely useful work rather than a novelty. If your team spans editors or you need SSO/SAML and on-prem deployment, this isn't the tool — it does one editor and stops there. The material caveat is availability: phion.dev currently serves a Vercel 503 DEPLOYMENT_PAUSED page, so confirm it's live before committing. For the same itch, generic dotfile and config managers remain the fallback.

Skip Phion if your team codes outside Cursor or spans multiple editors, since every feature here operates only on Cursor rules and config files.
.cursorrules files you already keep by hand aren't imported automatically, so budget time to re-create existing rules as templates before versioning helps you.
Chosen pricing model: freemium. Positioned as a low-cost add-on for individual Cursor users and small teams rather than a platform purchase. Compare against the $0 option of storing .cursorrules in your existing repo and against general dotfile/config managers, which cover more editors for similar or no cost. If your team is Cursor-only, the paid tier buys real-time sync and conflict detection you'd otherwise hand-roll.
In short
Phion.dev — Versioned Cursor rules management with backup, rollback, and one-click publishing for Cursor users. Best for Solo developers who run everything inside Cursor, Small teams standardizing Cursor behavior across projects, Cursor users tired of hand-editing .cursorrules files.

About Phion.dev
Phion.dev targets one specific itch: keeping Cursor rules from turning into a mess. If you've opened a Cursor project months later and had no idea which .cursorrules edits actually mattered, this tool is aimed at you. It automates Cursor rules management, versioning, and publishing so you don't hand-maintain config files in a text editor alongside your actual code. The workflow is small-team friendly. You keep coding in Cursor; Phion handles rule upkeep, backs up your configuration, and lets you roll back to a previous ruleset when an experiment goes sideways. Shared rules keep everyone's Cursor behavior consistent, conflict detection flags when two contributors' rule sets diverge, and custom templates let you start new projects from a known-good baseline instead of an empty file. Export to JSON and a CLI for CI/CD mean rules can move through the same pipeline as the rest of your project, and multi-project support with project-specific rule scoping keeps several Cursor projects from drifting out of sync. Phion treats rules as versioned artifacts rather than stray files, which is the whole pitch. Where it lives is where it stops: Cursor only. If your team codes in VS Code, JetBrains, Neovim, or a mix, Phion has no role in your workflow. Caution flag: as of this check, phion.dev returns a Vercel 503 DEPLOYMENT_PAUSED page stating the deployment is paused by the owner — verify the service is live before you invest time in it.
Behind the Verdict
Phion's core insight is that .cursorrules and Cursor configuration files are code artifacts that teams treat like litter. Versioning them, backing them up, and giving you a rollback path when a rules experiment degrades output is the right shape of solution, and it maps onto how developers already think about source control. Strengths, in order of practical value: rules history with rollback to a previous version; backup and restore of Cursor rules; rules conflict detection when two contributors' rule sets diverge; custom rule templates so a new project starts from a known-good baseline rather than an empty file; real-time rule sync across team members on the paid tier; and export to JSON plus a CLI for CI/CD, which is what makes rules movable through an existing pipeline rather than a manual chore. Multi-project support and project-specific rule scoping matter more than they sound — teams running several Cursor projects usually end up with copy-pasted rule fragments drifting apart. Weaknesses. Scope is the big one: Phion only works inside Cursor. Teams on VS Code, JetBrains, Neovim, or a mixed toolchain get nothing. There is no API for programmatic control, so custom automation beyond the CLI isn't available, and there is no SSO/SAML or on-prem/self-hosted option, which rules it out for larger organizations with procurement requirements. It also doesn't touch non-Cursor configuration files, so it will never be your general config layer. Where it fits: a Cursor-only solo dev or a small team that has felt the pain of inconsistent assistant behavior across projects and teammates. Where it doesn't: anyone with a mixed editor fleet, anyone who needs enterprise identity, and anyone who requires guaranteed uptime. That last point is not hypothetical — phion.dev currently returns a Vercel 503 DEPLOYMENT_PAUSED page stating the deployment is paused by the owner, so before you build a workflow around it, confirm the service is actually running. If it is, and you're Cursor-first, it's a focused add-on worth trialing against simply keeping your rules in the repo by hand.

Real-world workflow fit
Concrete scenarios for the personas Phion.dev actually fits — and what changes day-one when you adopt it.
Onboard a new project by picking a custom rules template instead of writing .cursorrules from scratch, then keep committing in Cursor while Phion backs up and versions each rules change.
Outcome: A project that opens months later still has an understandable, rollback-able rule history rather than one opaque config file.
Share one ruleset across teammates with real-time sync, and let conflict detection surface the moment two contributors' rule sets diverge.
Outcome: Everyone's Cursor behaves consistently, and rules drifts get flagged instead of silently changing assistant output per machine.
Export rules to JSON and drive them through the CLI in a CI/CD pipeline so rules changes are reviewed and shipped like any other project change.
Outcome: Rules stop being an informal side channel and become a reviewed artifact in the same pipeline as the code.
Use Cases
- Automate Cursor rules generation for new projects
- Roll back to a previous ruleset after a mistake degrades Cursor output
- Share consistent Cursor rules across your dev team
- Version control your Cursor configuration like code
- Publish your Cursor rules with a single click
- Keep Cursor rules in sync as your project evolves
- Start new projects from a known-good rules template instead of an empty file
Limitations
- Phion only works within the Cursor editor, so it's useless for teams using other IDEs.
- There is no API for programmatic control, limiting custom automation beyond the CLI.
- Enterprise features like SSO/SAML and on-prem hosting are absent, so larger organizations won't find it suitable.
- Phion doesn't handle non-Cursor configuration files, so it's narrowly scoped.
- Finally, availability is a real risk right now: phion.dev returns a Vercel 503 DEPLOYMENT_PAUSED page stating the deployment is paused by the owner, so treat uptime as unverified until you confirm the service is live.

Free
$0
Ideal for
Solo developer running a handful of Cursor projects who wants versioned rules and rollback before paying anything.
What this tier adds
Free entry point: automatic Cursor rules management, versioning and history, backup and restore, multi-project support, and one-click publishing.
Pro
$15/mo
Ideal for
Cursor-only small team that needs everyone's rules to match and wants rules flowing through a CI pipeline.
What this tier adds
Adds real-time rule sync across the team, rules conflict detection, custom rule templates, CLI for CI/CD, and JSON export on top of the Free tier.
Where the pricing makes sense
The company stage and team size where Phion.dev's pricing actually pencils out — and where peers do it cheaper.
Chosen pricing model: freemium. Positioned as a low-cost add-on for individual Cursor users and small teams rather than a platform purchase. Compare against the $0 option of storing .cursorrules in your existing repo and against general dotfile/config managers, which cover more editors for similar or no cost. If your team is Cursor-only, the paid tier buys real-time sync and conflict detection you'd otherwise hand-roll.
Setup time & first value
How long it actually takes to get something useful out of Phion.dev — broken out by persona, not the marketing-page minute.
Solo Cursor dev: minutes — connect the project and pick or create a rules template. Small team: expect an hour or so to agree on a shared baseline ruleset and invite contributors. CI users: add the CLI to an existing pipeline step; the export-to-JSON path is the main thing to wire up. All of this assumes phion.dev is live and not still showing the paused-deployment page.
Switching to or from Phion.dev
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From hand-edited .cursorrules files: capture your current rules as a Phion template, then use versioning and rollback going forward.
- →From .cursorrules committed directly in each repo: consolidate them into a shared ruleset so multiple projects stop drifting apart.
- →From copy-pasted rule fragments across projects: use project-specific rule scoping to give each project its own slice of a shared baseline.
- ↗To plain repo-managed .cursorrules: export your rules to JSON and commit them back into each project's repository.
- ↗To a general dotfile or config manager: export rules to JSON and fold them into your existing config-management setup.
- ↗To rolling your own CLI pipeline: use the JSON export as the source of truth and replace the sync features with your own scripted steps.
