Parallax IDE for Chrome

NOTICE (Updated Aug 2025): Google has deprecated the technologies that Parallax IDE is built upon. We've detailed what this means below, by platform.

Win/Mac Users: Chrome Browser support for Parallax IDE on Win/Mac ended Mar 2023; however, Parallax replaced the original Chrome Webstore Parallax IDE with a natively-installed version so you can continue to run today (see Win/Mac downloads at the bottom of this page). Further updates may occur; return here later for new information. (Also see BASIC Stamp Editor for Windows as an alternative.)

Chromebook Users: Per Google's Oct 2024 Announcement:

Education/Enterprise Users on Managed Chromebooks: Parallax IDE can still be installed and run if it is admin-installed using Google for Education/Enterprise tools, until Feb 2028 (upon release of ChromeOS v169), or until Oct 2028 (for Chromebooks using the "LTS" (Long Term Support) channel of ChromeOS releases).
Individual Users or Personal Chromebooks: Parallax IDE can no longer be user-installed and run (as of Aug 2025 with ChromeOS v139+).

Slow Downloads? If you're experiencing long delays at the start of every download to your board or bot, try turning off Bluetooth on your Win/Mac/Chromebook computer. Recent versions of Chrome and ChromeOS changed the way Bluetooth devices are presented to software that communicate serially. On certain computers, this adds a significant delay at the start of the board or robot download process when Parallax IDE requests a list of available ports from the OS. Turning off the computer's Bluetooth hardware before programming these devices makes this interaction much faster.

BASIC Stamp development software built as a Google Chrome Application. Runs on Chromebook, Linux, Windows, and Mac OS X. Download the Getting Started guide PDF here; this includes installation instructions and also the "Getting Started with Stamps in Class" guide. Then, get Parallax IDE from the Google Chrome Web Store. BASIC Stamp modules supported: BS2, BS2e, BS2sx, BS2p24, BS2p40, BS2pe. Note: Supports only a single program slot in multi-slot modules. Does not support BS1 or BS2px.

COPPA/PII Compliance: The Parallax IDE Google Chrome Application does not deliver any personally identifiable information (PII) to Parallax Inc. No registration email is required. If the end-user is logged into their Chrome browser or Chrome OS on a Chromebook, Parallax IDE automatically uses their Google Account's Google Drive to sync their local BS2 programs onto their cloud storage and back again. There's no actual log-in or any email address collection within Parallax IDE itself.

BUG NOTICE

On Chrome v92+, be sure to use Parallax IDE v0.14.4 to avoid a layout bug that causes the Debug pane to be obscured and the editor and files scroll bar to be hidden.
