== Using Free Trials
21
+
22
+
The Vaadin Trial experience lets you evaluate all Vaadin commercial features - such as Vaadin Copilot, commercial components (e.g., Charts), Acceleration Kits - with minimal effort:
23
+
24
+
- 7‑day Trial (no registration needed): Start instantly by clicking a button in the development tooling of a started Vaadin application,
25
+
- 30‑day Commercial Trial (registration required): Extend your evaluation by signing in to `vaadin.com`.
26
+
27
+
Both trials enable commercial features in development. Production builds during trials are allowed with an opt‑in flag and will display a visible runtime banner.
28
+
29
+
A trial period can be activated through Vaadin Dev Tools by clicking the `}>` button in the right bottom corner of the application's page and also through the automatic splash screen shown when a commercial component is used without a license.
30
+
31
+
Vaadin Control Center supports only the 30‑day Commercial Trial.
32

=== 7-day Trial Workflow (Seven-Day, No Registration)
34
+
35
+
When you use a commercial feature (for example, place a commercial component on a view or trigger a Vaadin Copilot function that makes changes to source code) and no valid license is found, a modal splash screen appears in development mode once you navigate to a view that uses a commercial component. It explains that a subscription or trial is required and offers two choices:
36
+
37
+
- Try for 7 days (no registration): Starts the 7‑day trial immediately.
38
+
- Log in / Sign up (to acquire or extend a license/trial): Opens Vaadin web-site to sign in and retrieve a license key or start the 30‑day trial.
39
+
40
+
It also shows the following information:
41
+
- Link to the commercial license terms
42
+
- Examples of Vaadin commercial products you have full access to.
If you choose Log in / Sign up from the splash screen, or when your 7-day Trial has expired, you’ll be guided to authenticate and start a 30‑day trial. This enables all commercial features for 30 days.
47
+
48
+
When a 7-day Trial expires, the splash screen shows guidance to "Extend trial 30 days" (via the login path). Once button is clicked, the trial starts immediately.
49
+
50
+
The 30‑day trial can be started again after 90 days per user/account.
51
+
52
+
=== Production Builds While Using a Trial
53
+
54
+
Production builds do not enable commercial features if you don’t have a valid license. However, you can opt‑in to enable commercial features in production builds by adding a `-Dvaadin.commercialWithBanner` system property or `commercialWithBanner` Vaadin plugin parameter that shows a visible persistent banner on the bottom of the page in runtime.
55
+
56
+
The banner links to the https://vaadin.com/commercial-license-info[Commercial License Info] page. It is closable, but reappears on page reload.
