What the plan includes

The Pro plan is $100 per month and covers:

• Full runtime and SDK access
• Every release as it ships, including major versions
• Studio workflow and plugin
• Domain-pack authoring and validation tooling
• Scenario testing and diagnostics tooling
• Release notes and migration notes for every breaking change
• No per-place or per-actor limits — execution happens in your own servers
• Technical support by email

Versioning

Releases are versioned MAJOR.MINOR.PATCH. A patch release fixes behaviour without changing an interface. A minor release adds capability that existing packs and adapters keep working across. A major release is the only kind that may change an interface you already depend on.

Every release ships with notes. A major release additionally ships a migration note that names each changed interface and what to do about it.

Breaking changes

The commitment is procedural, and it holds in both directions:

• Interface changes land in a major release, never in a patch.
• Every breaking change is published in release notes with a migration note.
• Pack validation reports which roles a change affects before you ship it.
• The previous major line keeps receiving security fixes for six months.

What is not promised

• No contractual uptime guarantee — the runtime executes inside your own Roblox servers
• No dedicated or named support engineer
• No custom domain-pack development or bespoke integration work
• No third-party security audit has been published.
