Season 21 added Layouts for saving and resuming configured sessions. Rare also revised the Season Pass and announced changes to the Insider Programme, though its planned 2026 relaunch is not confirmed by the current information.
How Rare’s Custom Servers plan became free Custom Seas
Rare’s announcements changed over time, so the July 2025 subscription proposal should not be mistaken for the feature that launched. The current product is Custom Seas, released with Season 20 on June 18, 2026, and Rare said it would be free to every player. Rare’s Season 20 announcement describes it as an in-game creative toolset for configuring sessions, creating modes and challenges, and building private worlds.

What can you do in Custom Seas?
Custom Seas puts session configuration and creative controls inside the game. Players can use switches and the Command Menu to adjust a session, then save settings as Presets. The announced tools include:
- Change rules and settings, including configuring a scoreboard.
- Spawn treasure, items, and wildlife to shape a challenge or activity.
- Use fast travel to move around a configured session.
- Use Free Camera for a cinematic view.
- Save a Layout in Season 21 to preserve a game state and the positions of spawned items for later use.
Rare’s announcements establish the feature’s launch and these documented capabilities, but do not provide a complete current list of limits or establish availability by platform or region. Consult the in-game menus and current official guidance for details that may depend on your setup.

What changed in the Season Pass?
Season 20 replaced the former 100-level reward track with a 50-level Season Pass organized into tiers with reward choices. The free pass remains available to all players; the Season Pass: Premium Tier is a separate optional paid addition with another pool of unlockable items. Rare also said players can use Ancient Coins to buy up to 10 levels per Season. Rare’s Season 20 announcement describes the revised pass.
Completing level 50 unlocks that season’s Star Prize. For Season 20, Rare named the Greed’s Reach Cutlass as the example. The Premium Tier was described as including a progression boost and Ancient Coins for Season 20; those details should not be read as a guarantee about the contents of every later season’s tier.

What changed in the Insider Programme?
In July 2025, Rare announced that it would lift the NDA for registered Insiders, allowing them to discuss, stream, and capture content from preview builds openly. Rare also said it planned to relaunch the Insider Programme in 2026. The available current information does not confirm that this planned relaunch has happened.
Rare’s Insider Programme FAQ, listed as updated June 16, 2026, describes preview-build access, newsletters, behind-the-scenes content, and an exclusive forum. It says participants need to own Sea of Thieves or have an active Game Pass membership, register on the Insider site with an Xbox Live account, and accept the programme terms. Check the FAQ for current registration and participation details.

What Rare said about its wider changes
Rare’s March 2026 recap said its three-Act content model was not working for its internal teams or player expectations. The same announcement introduced Limited Commercial Usage Guidelines for people making Sea of Thieves-inspired creations. Rare described their broad purpose, but the announcement alone does not establish the precise permissions or restrictions for selling particular work; makers should read the guidelines themselves before relying on them.
In that recap, Head of Community and Comms Christina “Fair Fight” McFairholme said, “We will not touch your gold.” The statement was a reassurance about the game’s health and economy in the context of Rare’s wider changes, not a description of Custom Seas access or Season Pass terms.
