## High●●●rts

Commercial use is paid, internal screens included. Prices are for Core (the basic charts); Stock, Maps and Gantt are bought on top.

| Product (per developer) | Internal, annual | Internal, perpetual | External, annual | External, perpetual |
| --- | --- | --- | --- | --- |
| Core | 185 | 425 | 366 | 839 |
| Core + Stock | 370 | 850 | 732 | 1,678 |
| Core + Maps | 250 | 574 | 494 | 1,133 |
| Core + Gantt | 222 | 510 | 439 | 1,007 |
| Core + Stock + Maps + Gantt | 443 | 1,018 | 876 | 2,010 |

- Internal covers in-house use only; SaaS/External covers one public app. Up to five external apps is SaaS+ (Core $1,099 a year).
- Prices rose about 5% between January and February 2026: Wayback Machine snapshots show $176 / $349 on 2026-01-03 and $185 / $366 on 2026-02-10. We found no official announcement.
- An annual license must stop being used when it lapses. A perpetual license keeps working, but new releases need a valid Advantage plan.
- Non-commercial use (such as education) falls under separate terms; check the official license page.

## Apex●●●rts

Since v5.0.0 (on npm 2025-07-09, announced 2025-06-26) it uses its own license, not MIT. v6 (2026-07-17), v7 (2026-08-25) and v8 (2026-10-09) followed; the latest is 8.4.1. Its official llms.txt says "No product is open source or unconditionally free". Many older articles still call it MIT.

| Tier | Price (annual, per developer) | Includes |
| --- | --- | --- |
| Community | Free if the organization's revenue, operating budget and funding are each under $2M; otherwise $199 | 25+ core chart types |
| Pro | $349 | + ApexGrid, ApexTree, ApexSankey |
| Premium | $599 | + ApexGantt, ApexStock and Premium-only features such as Waffle, Raincloud and Trellis |
| OEM | $14,999 per app | Redistribution in products and platforms others use |

- The $2M test adds up parent and affiliated companies. The 2026-10-01 license edit widened it from revenue to "revenue, budget or funding".
- Embedding it in a product or platform others use (your SaaS customers' screens, delivered solutions) needs OEM whatever your size; only non-interactive static charts are exempt.
- When a license key expires, paid features show a trial watermark.
- Prices have not changed from 2025-08 to 2026-10.

## AG Ch●●ts

- Community is free under MIT. Zoom, crosshairs and heatmaps are Enterprise features.
- Enterprise is $499 per developer (perpetual license plus a year of updates), or $1,498 bundled with AG Grid Enterprise. Prices did not change from 2025-01 to 2026-06. Deployment licenses and renewals are in the EULA, not on the pricing page.

## am●●arts 5

Free under a "linkware" condition, commercial projects included, as long as the logo link stays; a commercial license removes it. Prices have not changed from 2025-01 to 2026-10.

| Tier (per developer) | Charts annual / perpetual | Maps, Stock or Gantt each, annual / perpetual | Support |
| --- | --- | --- | --- |
| Basic | 80 / 180 | 64 / 144 | None ($190 a year extra) |
| Single App or SaaS website | 280 / 650 | 224 / 520 | First year included, then $190 a year |
| OEM | 1,200 / 2,700 | 960 / 2,160 | First year included, then $790 a year |

## light●●●ght-charts

The license text is Apache-2.0, but its README and NOTICE require a Trading●iew attribution and a link to tradingview.com on a page users can see; the `attributionLogo` option draws a logo link in the chart and satisfies it. It is the most used free choice for candlestick charts today.

## To●●t UI Chart

MIT, but the GitHub repository was archived on 2026-09-02 and the last release is v4.6.1 (2022-12-21). The license is fine; the maintenance is over. See [Moving from To●●t UI Chart](https://82chart.com/en/docs/migrate-toast-ui-chart/).

## 82chart

MIT. No license key, no watermark, no revenue threshold and no paid tier; zoom, crosshair, annotations, export, Korean units and accessibility are all in the free core. Products you deliver or redistribute only need the LICENSE text. Features are compared on [the comparison page](https://82chart.com/en/compare/).

## Frequently asked questions

### Is Apex●●●rts still free?

Conditionally. As of 2026-10-22 the Community tier is free while the organization's annual revenue, operating budget and funding (parent and affiliates included) are each under $2M; past that it is $199 per developer a year and up. Embedding it in a product others use needs OEM ($14,999 per app a year) at any size. It has not been MIT since v5.0 (July 2025).

### Can I use High●●●rts for free?

Commercial use is paid, internal screens included: Core is $185 per developer a year for internal use and $366 for an external app (after the February 2026 increase), with Stock, Maps and Gantt on top. Exceptions such as non-commercial education are separate terms.

### Which chart libraries are free for a company product?

82chart, Chart.●s, Re●●arts and AG Ch●●ts Community (MIT) and EC●●rts (Apache-2.0), without conditions. light●●●ght-charts is free with a Trading●iew attribution, am●●arts with its logo link. For Korean products that also want 만·억 units, zoom and export for free, 82chart.

### How do MIT and Apache-2.0 differ?

Both allow commercial use, modification and redistribution. MIT is short: keep the copyright and permission notice. Apache-2.0 adds a patent grant, asks you to mark changed files and to ship the NOTICE file if there is one.

### Can an open-source chart library become paid later?

A project can change the license of new versions (Apex●●●rts did at 5.0). Versions you already received under MIT generally stay usable under those terms, so pin versions and check the LICENSE file whenever you upgrade.
