Why I built Cepho

Danny - solo founder, self-taught developer

I noticed my brain doesn't really clock out of a project. The idea for a fix, or the thing that's actually wrong with a bug, tends to show up nowhere near my desk. Standing in line, on a train, stuck at a boring family thing.

Normally that idea is just gone by the time I'm back at my pc. I'd lose the thread, or I'd default to scrolling instead, even though half my head was still on the project the whole time.

Cepho is the fix for that specific gap. Not a replacement for your setup, not a new IDE, not remote access to your machine. Just your actual files, available the second you think of something, so the moment doesn't die before you get back to your desk.

Cepho is named after the octopus for a reason. What you're looking at is one arm. Core is the first of several. More are already being built.

What it looks like

Cepho chat planning a landing page for NovaNotes

Plan with Cepho. Outline the work before any code.

Cepho build complete with ten files ready

Build complete. Files ready in the cloud for your IDE.

Cepho manual mode with file tree and code editor

Manual + file tree. Browse and edit files on your phone.

Where Cepho fits

A few other ways people already solve parts of this. All of them are solid tools for what they're built for. Here's the honest breakdown.

Tool Your actual project?
The real codebase you were working in on your pc, not a cloud copy, a fresh sandbox, or a separate environment.
No pc required?
Doesn't need your computer on, awake, or reachable. Different from "remote control," which drives a machine that has to stay running.
Native mobile UI?
A real app built for touch and small screens. Not a terminal or a desktop site squeezed onto a phone.
Getting started?
What it actually takes to go from zero to working, every option requires something.
SSH / Termius Yes No, pc must stay on Terminal only Port forward or dynamic DNS, then pair the app
GitHub Codespaces No, cloud copy Yes Browser only GitHub account + Codespace config
Replit No, own environment Yes Browser only Account + rebuild your project inside Replit
Cursor Mobile Only in "control my pc" mode Depends on mode used Yes App + account, plus pc setup if controlling your machine
Claude Code mobile Only with Remote Control Depends on mode used Yes App + account, plus Remote Control setup on your machine
Cepho Yes Yes Yes Extension in your editor + app, pair once

Questions

What is Cepho?

Your VS Code project lives in the cloud (also works with Cursor). Open your phone and everything is there, even if your pc is off.

How is Cepho different from Cursor Mobile, Replit, or Claude?

Cursor Mobile is Cursor's app, not your actual project. Replit is a browser IDE, not your existing repo. Claude on mobile has no clue what files you have. Cepho connects your real workspace to your phone and back.

Does my pc need to be on?

No. Files and chat live in the cloud. Changes sync back to your IDE when you're back at your desk.

Which editors work with Cepho?

VS Code and Cursor. Install the extension, open your project, pair from the app and you're good. More editors coming.

How does sync work?

Only changed files upload. Save in the IDE and the cloud updates. Edit on mobile and the changes apply in VS Code when you're back. Runs in the background, nothing to think about.

What does it cost?

Waitlist is free. First 25 get founding-member Pro benefits (4 months Pro free then 50% off). After that there's a free tier and Pro at $10/mo.

Can I try it now?

Join the waitlist and set up the Cepho extension for VS Code (also works with Cursor). Android is in Closed Testing on Google Play. New signups are added on an ongoing basis, and we'll email you when you're in.

Step 3 · v0.2.43

Install Cepho Sync

Real setup. Pick your editor, install once, connect once, wait for Synced. Most pain comes from the wrong CLI or two Active syncs.

1. Pick your editor

VS Code and Cursor are different apps. They use different terminal commands.

  • VS Codecode
  • Cursorcursor

If the command is missing, install it in PATH from that editor:

  • VS Code: Command Palette → Shell Command: Install 'code' command in PATH
  • Cursor: Command Palette → Shell Command: Install 'cursor' command in PATH

Then open a new terminal (or close and reopen PowerShell) so PATH updates.

2. Windows (PowerShell)

Copy the command for the editor you actually use. Version is 0.2.43.

Cursor

iwr https://cepho.cloud/downloads/cepho-0.2.43.vsix -OutFile $env:TEMP\cepho.vsix; cursor --install-extension $env:TEMP\cepho.vsix --force

VS Code

iwr https://cepho.cloud/downloads/cepho-0.2.43.vsix -OutFile $env:TEMP\cepho.vsix; code --install-extension $env:TEMP\cepho.vsix --force

If PowerShell says the command is not recognized, go back to step 1 and install the shell command, then open a new PowerShell window and run again.

3. Mac (Terminal)

Same rule: use cursor or code for the editor you opened. Install that shell command in PATH first if needed (step 1).

Cursor

curl -L -o /tmp/cepho.vsix https://cepho.cloud/downloads/cepho-0.2.43.vsix && cursor --install-extension /tmp/cepho.vsix --force

VS Code

curl -L -o /tmp/cepho.vsix https://cepho.cloud/downloads/cepho-0.2.43.vsix && code --install-extension /tmp/cepho.vsix --force

4. After install

  1. Reload Window: Ctrl+Shift+P (Win) / Cmd+Shift+P (Mac) → Developer: Reload Window
  2. Open the correct project folder (the real repo root, not a parent or random subfolder)
  3. Run Cepho: Connect to Cepho (same email as the app)
  4. Approve once in the Cepho app
  5. If .cepho.json already exists (0.2.43+), Connect will not create a second project. That is normal.
  6. Wait for Synced ✓, not just Connected
  7. In the app: keep only one Active sync for that project

5. If anything fails: try this before writing support

  • Wrong CLI: You ran code but use Cursor, or the other way around. Reinstall with the matching command from step 2 or 3.
  • Dual connections: In the app, Remove both IDE connections. In the project folder run rm -f .cepho.json. On Mac also clear ~/.cepho/pairing.json if it is stuck. Connect once. Approve once.
  • Red status flashing: Run Cepho: Copy diagnostics → paste that when you ask for help.
  • Stuck after Connected: Run Cepho: Install background daemon, then Cepho: Sync now. Wait for Synced ✓.
  • Files empty in the app: Check only one Active sync, and that the editor opened the right project folder.
  • Manual VSIX fallback: Download cepho-0.2.43.vsix → Command Palette → Extensions: Install from VSIX... → pick the file → Reload Window.

Longer walkthrough (pairing, daemon, reverse connect): extension guide. Marketplace can lag behind this VSIX. Use 0.2.43 from here.
