Old School RuneScape Client Choice: Desktop, Mobile, RuneLite, or HDOS?

Choose by the device you actually use

Jagex's New Player Guide (August 12, 2025) says its Official Client is the option available on both desktop and mobile (Android and iOS), and separately names RuneLite and HDOS in its Jagex Launcher client discussion. That is a snapshot of what the article documents; it does not prove that every client works on every device, operating system, or current launcher build.

A cautious install sequence

The sequence is a risk-reduction recommendation based on Jagex's dated phishing warning, not a claim that a particular client or download was scanned. A Jagex-listed third-party client is not automatically safe from every later compromise, fake mirror, or incompatible plugin.

1. Confirm the title is Old School RuneScape, not RuneScape (RS3), and note your device and operating system.
2. Open Jagex's New Player Guide and current client support page directly; check whether its client list or launcher steps have changed since the guide's August 2025 date.
3. Use only the client download link Jagex currently provides or explicitly points to. Do not select a similarly named search result or an unsolicited launcher download.
4. Read the target client's current supported OS, update, and account sign-in requirements before installing; Jagex's historical guide does not audit today's device support.
5. If an error remains, record the exact client name/version, operating system, launcher, and message before consulting Jagex support or comparing a community thread.

What this client guide cannot establish

The cited article does not benchmark performance, guarantee that a plugin is permitted, recover an account, validate an installer, or list every supported OS/version today. It also does not establish a RuneScape (RS3) client choice. Treat its date as the evidence boundary and use Jagex's current notices for present installation steps.

If the launcher or client does not match the guide

This is a low-risk triage sequence, not a repair procedure or a claim that a current launcher fault is known.

1. Do not uninstall or move account data just because a menu differs from the August 2025 screenshots or wording.
2. Confirm that you opened OSRS and record the exact client, launcher, device, operating-system version, and message shown.
3. Open the current Jagex client/help page from Jagex's site and compare its present steps; the dated article is a starting point, not proof of today's interface.
4. If sign-in or account security is involved, stop before sharing codes or credentials and use Jagex support directly.

Before you play

• I confirmed I am launching Old School RuneScape, not RuneScape (RS3).
• I matched the client choice to desktop or Android/iOS instead of assuming mobile parity.
• I followed a client link from Jagex's current documentation and avoided search ads or mirrors.
• I recorded client, OS, launcher, and exact error before relying on a community post.

Sources & revision notes

Editorial revision: November 6, 2026; not a gameplay test date. The reference notes identify source limits and version differences.

1. Jagex: New Player Guide — Settings & Set-Up (Official)

   Jagex guide dated August 12, 2025. It describes the Official Client as the client listed for both desktop and mobile and names RuneLite and HDOS as supported client options in the Jagex Launcher. Because client support and launcher behavior can change, re-check this Jagex page before installing; this article does not independently test or certify client downloads. The page also contains dated statements about features then in development that are intentionally not repeated here.

2. Old School RuneScape Wiki (Community)

   Community-maintained reference that Jagex's 2025 new-player guide links and describes as player-driven. It can help locate mechanics and terminology, but it is not the primary authority for client security, account status, or a live patch. Confirm sensitive account decisions in current Jagex help pages.

3. Old School RuneScape Steam Community Discussions (Community)

   External player-created discussion board. Posts are anecdotal, may refer to a different client or game mode, and are not Jagex support or GamerWin-verified reports. Match OSRS vs RuneScape, platform, client, mode, and date before using a post as a clue.
