Sandbox
What the free Sandbox is, who it's for, and how to start one.
The Sandbox is a free test account for developers proving a Coassemble integration inside their own product before choosing a plan. It gives you the complete platform and the full API, with allowances sized for testing and validation, so you can build a working proof of concept before any commercial conversation.
Who is the Sandbox for?
The Sandbox is code-first. It's for developers and product teams testing a Coassemble integration in their own product, intranet or platform, and for consultants or platforms validating that Coassemble fits how they deliver learning. Without a developer it won't get you far.
If you just want to build courses and share them with your team, talk to the team instead. They'll help you find the right option.
The Sandbox is an evaluation environment. It isn't a free tier for running live training.
What can I do in the Sandbox?
You get the same platform and the same API as every paid plan. Create courses with AI (from a prompt, a document or a PowerPoint), refine them, build against the full REST API and every embeddable mode, test the learner experience inside your own product, and check that completions and reporting flow the way you need before you commit.
What are the Sandbox limits?
Sandbox allowances for Identified Recipients, Anonymous Recipients and AI usage are sized for validation. They're a one-off evaluation budget that doesn't refresh each month: enough to prove your integration works. When you're ready for real usage, the conversation moves to a plan sized for it.
How do I start a Sandbox?
- Go to coassemble.com and select Get your sandbox.
- Under What brings you here?, choose Get my hands on the API. (The other two options send your details to the team instead of creating a sandbox.)
- Enter your work email, company, role and your product's website, choose when you want to be live, and tell us how you heard about us. Free email domains such as Gmail or Outlook.com aren't accepted for a sandbox.
- Select Open my sandbox.
- When your sandbox is ready, select Open your sandbox (or wait a few seconds and you're taken there).
- Set your name and password, then select Continue to reach your new workspace.
This usually happens straight away, with no credit card required. We also email you the link to your sandbox, which is valid for 7 days, so you can pick it up later. If the sandbox isn't ready yet, the screen says so and the team follows up by email. If your email already has a Coassemble account, you're asked to sign in instead.
What happens after the Sandbox?
When your integration is proven, you move to a paid plan through a conversation with the team. Everything you've built in the Sandbox carries over, so there's nothing to rebuild.
One thing to do after you upgrade: create a live (Production) API key for your integration. Your Sandbox test keys stay test keys.
Frequently asked questions
Is the Sandbox really free?
Yes. The Sandbox is completely free, with no credit card required.
Are any features missing from the Sandbox?
No. The Sandbox carries the same platform and the same API as every paid plan, including premium AI voices. Three things are different:
- Allowances: they're sized for testing and don't reset.
- API keys: the Sandbox uses test API keys. Paid plans use Production API keys and can also create Test keys.
- Test mode badge: Sandbox courses show a Test mode badge to learners. The Coassemble logo is hidden on Sandbox courses.
Can I run live training on the Sandbox?
The Sandbox is for testing and validation. Once you're ready to deliver learning to real users at production scale, talk to the team about a plan.
Do Sandbox allowances reset each month?
No. Sandbox allowances are a one-off evaluation budget for proving your integration.
Will I lose my work when I move to a paid plan?
No. Your Sandbox workspace carries over to your paid plan, so courses, content and configuration come with you. Create a Production API key once you've upgraded, because your existing test keys stay test keys.
Can I have a separate workspace for testing or staging?
Yes. Talk to the team, or sign up for a Sandbox with a different work email address. Signing up again with an email that already has a Coassemble account asks you to sign in instead of creating a new sandbox.
Your test workspace and your live workspace aren't linked, so nothing moves between them automatically. To move a course across, duplicate it and pick the other workspace as the destination. That option only shows when your login has access to both workspaces.
A Sandbox runs on a one-off evaluation budget that doesn't reset. If you need more room for ongoing testing, talk to the team.
