OSRS private servers
An OSRS private server is an independently operated game based on the Old School RuneScape experience, with its own accounts, client and rules. It is separate from official OSRS: your official character, items and membership do not move across.
What “RSPS” means
RSPS stands for RuneScape private server. For an OSRS player, much of the vocabulary may already be familiar—skills, equipment, Slayer, Ironman and bossing—but the operator decides how those systems work on its server.
Sarim is an independent project, not affiliated with or endorsed by Jagex. You connect through the Sarim launcher and use a separate Sarim account.
Decide what you want to change
You might want a different training pace, new ways to build around equipment, a self-sufficient group account or custom encounters. Compare those features directly. The RSPS label alone tells you none of their exact rules.
| If you care about… | Check… | On Sarim |
|---|---|---|
| Training pace | The base XP rate, bonuses and change rules. | 25×, 10× and 3× difficulties. |
| Earning your own gear | Trading, banking and group restrictions. | Six account modes. |
| Custom builds | Effects, eligible equipment and how upgrades are obtained. | Account perks and item attachments. |
| A continuing account | A published reset or seasonal policy. | No-server-reset commitment. |
OSRS-like and semi-custom describe a direction
An OSRS-like server generally aims to stay close to familiar content. A semi-custom server adds or changes systems while retaining that foundation. These are broad descriptions; always check the actual mechanics.
Sarim describes itself as semi-custom. For example, Deadeye is an account perk for ranged PvM, while Trailblazer is an attachment placed on boots to gain bonus Agility XP from other training. They are acquired and managed through different systems.
Before your first download
- Use the server’s own download page. For Sarim, start at sarimps.com/play/ and read the prerequisites.
- Create separate credentials. Use a password you do not use for OSRS, email or another server.
- Read the choices before confirming. Check account restrictions, XP difficulty and the consequences of later changes.
- Find the support and update pages. You should know where to check a setup error or a maintenance announcement.
- Understand purchases before paying. Look for concrete benefits and delivery instructions rather than relying on a label.
What about RuneLite?
Some servers use their own RuneLite-based client. Sarim’s client includes Perks, Hub and Shops tools. It is separate from the regular RuneLite installation used for official OSRS; plugin availability depends on Sarim’s client.
The client guide explains those tools. Play has the installation instructions.
A concrete first look at Sarim
Begin with the account and XP choices, then use your free level-5 account perk in a first activity. Later, you can turn eligible spare equipment into Workbench materials and add effects to the gear you use.
That gives you two distinct build decisions: which account perks to activate and which attachments to put on equipment. The first-session guide connects the setup steps; the Wiki covers the individual systems.
Quick answers
Can I use my official OSRS account?
No. Your Sarim account and progress are separate. Do not enter your Jagex credentials in the Sarim client.
Does a higher XP rate remove all progression?
No. XP pace is one part of the rules. Equipment, resources, account restrictions and encounter unlocks still matter.
Is Sarim free to try?
The launcher and access to the game are free. Optional purchases have their own benefits and delivery details.
Where should I begin?
Read the mode comparison and XP choices, then follow Play. If you are still comparing servers, use the evidence checklist.
