HEWA

Every part of HEWA, and what it does today.

Eleven areas, in the order you meet them in the product. Each line is one thing you can open and use now, with what it is for.

A project open in HEWA in a Chrome tab: file tree, editor, terminal and the agent panel after a finished build. Figures in the drawing are illustrative.

01Editor and files

Editor and files

A code editor with a file tree, project search, quick open and inline autocomplete, in a browser tab. On a phone the layout rearranges itself for a thumb and a small screen.

  • Browser code editor (Monaco)Write and edit real code in the browser with nothing to install.
  • File tree with create, rename, duplicate, deleteOrganise your project files the way you would on a laptop.
  • Project-wide search and replaceFind anything across your whole project in one place.
  • Quick open files (Cmd+P)Jump to any file by typing part of its name.
  • Code intelligence (Monaco TypeScript worker plus server symbol lookup)Autocomplete, hover and go-to-symbol while you type.
  • Inline tab autocomplete (HEWA Instant)Finish lines of code with one keypress, even on a slow connection.
  • Command palette (Cmd+K)Reach every action from the keyboard.
  • Git panel (status, stage, commit, branches, diff, log, pull)See your changes, branches and history without leaving the browser.
  • Mobile layout and keyboard barBuild from your phone when that is the computer you have.

02Terminal and runtime

Terminal and runtime

npm and shell commands run inside the tab in Chrome and Edge. When your own device is weak, a cloud sandbox gives the project a real Linux shell instead.

  • In-browser terminal (WebContainer, Chrome and Edge)Run npm and shell commands right in the browser tab.
  • Cloud sandbox terminal (server runner)A real Linux shell for your project when your own device is weak.

HEWA runs in Chrome and Edge on a laptop or desktop; on an Android phone, the editor, agent and preview in Chrome. In Safari and on iOS you can edit, build, preview and export; the live terminal is not available there.

03The build agent

The build agent

Describe what you want. The agent writes a plan, then the files. In chat, the agent proposes commands and waits for a yes. A build writes its files, installs and previews; every file it wrote can be undone with one click. Stop it whenever you like.

  • Composer modes: Ask, Agent, Plan, DebugChoose whether the agent talks, plans, builds or debugs.
  • Plan first, then approve and executeSee the steps before any code is written, then say go.
  • AI build agent (Agent mode writes files)Describe the app you want and watch the files appear.
  • Live preview of the built appSee your app running the moment the agent finishes.
  • Self-fix after a failed installIf dependencies fail to install, the agent tries to repair the setup once.
  • Stop button; no charge if stopped before output completesChange your mind mid-build and you do not pay for what you stopped early.
  • Keep / Undo for an applied agent editRoll back an edit you do not like with one click.
  • Review and accept/reject proposed edits (per file and per hunk)Approve each change before it lands in your files.
  • Approve, edit or reject commands the agent wants to runNothing runs in your project until you say yes.
  • Agent Run panel (server-side multi-step agent loop)Hand the agent a goal and let it read, run and edit until it is done.
  • Server-side checkpoints with one-click restoreGo back to how the project was before the agent touched it.
  • Review a whole agent run as one changesetAccept or reject everything the agent did in one review.
  • Continue a stopped runPick up where the agent stopped.
  • Background agents / job queueLeave the agent working while you do something else.
  • Inline edit in the editor (Cmd+K on a selection)Highlight some code and tell the agent how to change it.
  • Fix with HEWA from a diagnosticTurn a red squiggle into a fix with one click.
  • Paste an image into chatShow the agent a screenshot or a sketch instead of describing it.
  • Web search in chat (@web)Let the agent look things up on the web when it needs to.
  • Saved chat history per projectCome back to any earlier conversation with the agent.
  • Custom MCP servers in the IDEPlug your own tools into the agent.

04Context

Context

Point the agent at exactly what it should read: a file, a folder, a web page, or the rules you wrote for the project.

  • @-mentions in chat (@file, @folder, @web)Point the agent at exactly the files it should read.
  • Pin files as contextKeep important files in the agent's view.
  • Codebase-aware chat (indexing + retrieval)Ask questions about your own code and get answers that fit it.
  • Project rules file (.hewa/rules.md or AGENTS.md)Tell the agent your project's conventions once and it follows them.
  • @docs and @git mentionsPull in docs and git history as context.
  • Auto-context from the active fileThe agent already knows which file you are looking at.

05Preview and sharing

Preview and sharing

The running app opens beside the code the moment the agent finishes.

  • Live preview of the built appSee your app running the moment the agent finishes.
  • Shareable preview links on an isolated preview domainSend a friend a link to try what you built.

06Bring your code

Built it somewhere else? Finish it in HEWA.

Import a public repository by URL, or open a folder from your computer. Your project can leave as a zip file at any time.

  • Import a public GitHub/GitLab/Bitbucket repo by URLStart from code you already wrote somewhere else.
  • Open a local folder (File System Access API)Bring a project from your computer into HEWA in a couple of clicks.
  • Download project as zipTake your whole project with you as a zip file at any time.
