Context

**Replit** — Browser IDE with agents, instant apps, hosting, and deployment. It currently costs $25/mo.

A dev container plus code-server plus deployment can replace some value, but Replit's beginner-friendly cloud IDE, agents, secrets, hosting, and zero-setup environment are a platform.

This brief describes a focused, single-operator replacement for the part of Replit that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.

What you are building

Run code-server in a cloud VM, add templates, secrets, git, AI coding extension, and one-click deploy scripts.

Build the focused developer workflow you use repeatedly, with local configuration.

A responsive interface with real empty, loading, success, and error states.

Requirements

Functional

Cloud VM/container platform.

Code-server.

Domain/HTTPS.

Deploy target.

Backups.

Data and integrations

LLM API.

Each of these needs a real account, credential, or quota. Set them up before writing feature code.

Non-functional

Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.

Security: server-side secrets, validated input, and no credentials in the client bundle.

Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.

Portability: the operator can export their data and leave without losing it.

Implementation brief

Build me a personal cloud dev environment to replace Replit, on a VPS I already have.

Requirements:

code-server (VS Code in the browser) behind Caddy with HTTPS and basic auth, installed

by one setup script. This is assembly of good parts, not a new IDE.

A `dev new <name> --template node|python|static` CLI that copies from a templates/

folder (each with .gitignore, README stub, and a run script) into ~/projects/<name>

and runs git init.

Each project gets a port in projects.json; Caddy routes <name>.dev.mydomain.com to it,

so anything I run is instantly viewable at a URL.

`dev deploy <name>` commits and restarts the project's systemd user service; `dev logs

<name>` tails it.

Per-project secrets in <project>/.env, never committed; the template .gitignore

enforces it.

Nightly tarball of ~/projects to a backups/ folder, keep 7.

Reachable only over HTTPS with auth (bind to a VPN interface instead if one exists);

no telemetry.

Out of scope: multiplayer editing, hosted AI agents, and per-project containers. One

VPS, one user, my own projects.

README: the wildcard DNS record, Caddy config, and code-server auth setup.

Delivery standard

Inspect the repository first, then write a short implementation plan before writing code.

Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.

Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.

Include responsive layouts plus genuine empty, loading, success, validation, and failure states.

Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.

Add structured logs around every external call and return actionable errors without leaking sensitive details.

Write unit tests for the core logic and one automated test of the main user journey.

Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.

Acceptance criteria

A clean install starts the app using only the README and .env.example.

The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.

Invalid input, missing configuration, provider failure, and an empty database each have a usable state.

The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.

Tests, type checking, linting, and a production build all pass with no ignored failures.

No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.

Non-goals

Do not build these, and do not claim to have replaced them:

Zero-setup browser IDE.

Hosted agents.

Multiplayer.

Templates.

Reliability at the vendor's scale is an operations problem, not a prompt.

The last 20 percent is sync, migration fidelity, speed, and edge cases.

What you still own after launch

Secure credentials, rotate secrets, and handle provider rate limits.

Run migrations, backups, restores, and dependency updates.

Test the critical journey after every model, API, or hosting change.

Monitor failures and fix the edge cases a first prompt will miss.

Risk

**Operational risk.** The code is achievable; dependable data, integrations, and ongoing operations are the real cost.

Editorial confidence in this assessment: medium. No independent one-shot implementation is linked yet.

Prior art
