The problem

The time you lose before writing code

2 to 5 hours a week reconstructing environments: wrong runtime, mixed .env, forgotten services, outdated setup docs. Zero lines of product.

Mixed versions

Mixed versions

  • One project needs Node 18, another Node 22, another Python 3.12 or Rust nightly.
  • The editor opens fast, but the environment isn't always aligned.
  • The failure shows up late: while installing, compiling, running tests or starting services.
  • Switching stacks manually breaks your focus and multiplies small errors.
Leaked variables

Leaked variables

  • .env, tokens, URLs, ports and flags change between projects.
  • Reusing terminals mixes context without warning.
  • A wrong DATABASE_URL can break tests or touch data it shouldn't.
  • Debugging leaked configuration takes more time than writing the feature.
Endless onboarding

Endless onboarding

  • Every repo has different steps to install, configure and start.
  • Documentation rarely reflects the real state of the project.
  • Variables, local services, ports or exact versions are missing.
  • Day one is spent getting the environment up, not shipping code.
Mixed context

Mixed context

  • You run the right commands in the wrong project.
  • You recall history from another folder without realizing it.
  • Ports, services and processes stay open between contexts.
  • Switching client, repo or stack should be safe, not a roulette.

Mixed versions

You switch projects and your terminal keeps using the previous runtime. Everything looks fine until npm install, cargo build or the tests fail because of a version you weren't even touching.

Leaked variables

A variable from another project stays loaded in your session and the bug looks random. The problem started in the environment, but it blows up much later in tests, APIs or data.

Endless onboarding

Joining a repo shouldn't be an archaeological dig through an old README, Slack messages and commands that "work for someone".

Mixed context

When several projects share terminals, history, ports and recent commands, making mistakes stops being rare: it's only a matter of time.

The solution

One manifest per project. The right environment every time.

Nexenv doesn't replace your editor, Docker, nvm, pyenv or your current tools: it coordinates them around every project. A declarative manifest per project captures runtime, variables and services, so opening a project takes seconds, not minutes.

Isolated context

Isolated context

  • Environment variables separated per project.
  • Runtime and commands defined from the manifest.
  • Project state visible before you start working.
  • Fewer errors when switching between clients, stacks or old branches.
Auto-detection

Auto-detection

  • Detects package.json, requirements.txt, Cargo.toml, Dockerfiles and more.
  • Identifies technologies, scripts, dependencies and structure.
  • Flags missing pieces before they block the setup.
  • Helps you create the initial manifest without starting from scratch.
Order from the start

Order from the start

  • Templates to start projects with best practices.
  • Scan to understand existing projects.
  • Recipes to add technologies, services or scripts without improvising.
  • One single flow to create, open, maintain and evolve projects.
Instant open

Instant open

  • Open from Desktop or CLI: one click or nexenv open.
  • Right editor: VS Code, Cursor, Zed, Neovim or others.
  • Operational context loaded from the manifest.
  • Picking up an old repo stops being a reconstruction session.

Isolated context

Every project opens with its own context: variables, runtime, scripts, services and editor. Without dragging configuration from another repo.

Auto-detection

Nexenv scans the repo and understands what it's looking at: stack, key files, package managers, runtimes and configuration signals.

Order from the start

Create new projects with a consistent base or register existing repos to turn setup chaos into a clear, repeatable configuration.

Instant open

Open the project and jump straight back to where you were: right workspace, loaded context, clear services and ready commands.

Flow

That simple

01

Register or scan

Point Nexenv to a new or existing folder. It detects the stack, organizes the technical context and prepares the project base.

02

Define the context

Runtimes, variables, services and project rules stay organized so you don't depend on remembering manual steps.

03

Get back to work

Open the project with its correct context and resume it today, tomorrow or months later with much less friction.
