What JSpark+ adds
JSpark is one app in two Editions: JSpark, which is free, and JSpark+, unlocked with a License Key.
JSpark is free, and not a trial: it doesn't expire. There is one download for both Editions. Everything not listed below is the same in both: the editor, Run, Run as you type, Peeks, the Timeline, web pages, Tailwind and updates.
JSpark and JSpark+ side by side
| JSpark | JSpark+ | |
|---|---|---|
| Tabs | 3 open at once | As many as you like |
| npm packages | Search npm and read READMEs. Starter packages and CDN imports work. | Install, update and remove any package |
| Library | Browse, search, open, copy, delete and export | Save and edit Saved Snippets, and import a Library |
| A page with a server | Not available | The Web Page + Server and React + Server Starters |
| Timeline | Up to 5,000 Steps, Lines detail | Up to 2,000,000 Steps, Inside lines, the Call Stack |
| Peek | The value | The value from every pass |
| Running | Time limit up to 5 s, memory 1 GB | Time limit up to 10 s, memory from 256 MB to 8 GB, and Run longer |
| Looks | App Themes Sunny and Night, Code Themes Plain and Moss, Fira Code without ligatures | Every App Theme, Code Theme and font |
| Editor | Format Code when you ask. Tailwind styles work. | Format before running, and Tailwind suggestions |
| Starters | Every Starter but the two with a server, in the default order | Reorder and hide Starters |
A limit never takes anything away. If you go back to JSpark, your Saved Snippets stay readable and openable, installed packages keep working, open tabs stay open, and settings keep their values. Only adding more past a limit stops.
Yearly and Lifetime
- Yearly, $19 a year: JSpark+ while you pay. If it ends, the app is JSpark again, with all your work kept.
- Lifetime, $59 once: JSpark+ for good, in every future version.
Both are for one person. One License Key works on up to 3 computers, Mac or Windows. Polar sells the keys and handles the payment and the tax. Any payment can be refunded within 30 days. Compare the plans on JSpark+, and read the terms of use and the refund policy.
Unlock JSpark+
JSpark tells you about JSpark+ only when you reach a limit. There are no timers, countdowns or reminders. The message names what you asked for and what JSpark+ adds:
JSpark+ keeps as many Snippets open as you like. In JSpark, close a tab to open another.
- Click Unlock JSpark+…, or Not now to go on as you were.
- Buy a plan. Your License Key comes by email.
- Paste the key into JSpark. JSpark+ is unlocked in place, with no new download.
Unlocking needs a connection once. After that, JSpark+ works offline. See Your License Key.
The pictures show JSpark on a Mac. On Windows, the window looks a little different and uses Ctrl for ⌘, but everything works the same way.
