Pet Simulator 99 Scripts for Delta Executor (2026)
Scripts below load from our auto-updating library and are community-submitted — verify before running. A loadstring executes remote code, so prefer open-source hubs and never run scripts from video comments.

What this page gives you: the full Pet Simulator 99 script library above — searchable and copy-ready — plus a 3-question picker that matches a hub to your device and goal, honest status labels on every featured hub, what to do when a script breaks after an update, and honest answers on bans, keys, and fake scripts.
Pet Simulator 99 has the most hostile script environment of any game on this site — not because of anti-cheat, but because of thieves. Attackers post “mailstealer” scripts disguised as fixed versions directly under legitimate scripts in comment sections; one hub author had to pin “DO NOT TRUST THE PS99 SCRIPTS IN THE COMMENTS BELOW! THEY ARE MAILSTEALERS!” on his own page. Add key-system fatigue, low-RAM crashes during coin farms, and BIG Games updates that silently break farm remotes, and you get a game where which source you trust matters more than which hub you pick. Hub status below is community-reported, and rows the owner can’t verify against the script library stay marked unverified.
How to read this page: hub entries are checked against the site’s script library and each hub’s official source where possible. Claims that rest on community reports rather than confirmed testing are labelled as such, and table rows that can’t be verified stay honestly marked unverified — a short honest table beats a long stale one.
Why Pet Simulator 99 scripts stop working (and why it’s not your fault)
Three things kill scripts, and none of them are you doing something wrong. First, Roblox’s anti-cheat patches land frequently — often around monthly — and each one can break how executors inject. Second, BIG Games updates change the RemoteEvent and DataStore paths scripts call — the classic symptom is the GUI loading fine but nothing happening, because the menu is client-side while the farm actions silently hit a dead server endpoint. Third, script authors move or delete their repos, so old saved loadstrings die with 404s even when the hub itself is alive.
One PS99-specific pattern: don’t confuse the two keys. Delta’s executor key and a hub’s script key are different systems with different expiries — and some SEO pages misinform users that Delta itself needs a “receive key” flow. Delta mobile needs its 24-hour key; whether the script needs one depends on the hub.
Note: Pet Simulator 99 and Pet Simulator X are different games — scripts are NOT interchangeable. A PS99 script will not work in Pet Simulator X, and vice versa. Only use hubs and loadstrings built for Pet Simulator 99.
What to do after a Pet Simulator 99 or Roblox update
- Don’t paste old saved loadstrings — re-copy the loader fresh from the hub’s official source; outdated loaders are the most common silent failure.
- Check the hub’s official source or Discord for a patched build; never re-download from a random copy.
- Update in this order: Roblox app → Delta Executor → get a fresh key → then test scripts. Roblox client updates have broken Delta itself (especially on iOS), so the executor update isn’t optional.
Which hub should you use? Answer 3 questions
There is no single best hub — only the best hub for your situation. Answer these three:
- What device are you on? Android handles most hubs; iPhone needs a hub confirmed working on Delta iOS; PC-via-emulator can run heavier ones. Mobile-only warning: some scripts are too large for mobile executors to hold — prefer short loader loadstrings (which fetch the real payload) over pasting full source code, and prefer hubs that explicitly market mobile support.
- What’s your goal? Coin farming → auto-farm hubs with FPS-booster modes. Hatching → auto-hatch hubs with luck boosts (mind the intervals — see safety). Trading → trade-alert hubs (never auto-accept “favorable” trades — see the fair-play note in safety). Index/collection → auto-rank and auto-quest hubs. Events → event-automation hubs, with the caveat that minigame automation is the first thing to underperform on mobile.
- How strong is your phone? Coin farms on 2–4GB phones are specifically named in Delta troubleshooting as an OOM-crash scenario. Use the hub’s FPS booster or white-screen mode, disable animations, lower graphics, close background apps — and expect budget devices to struggle with overnight farms regardless.
Hub shortlist
| Hub | Best for | Light or heavy | Hub key required? | Delta Android / iOS | Last tested | Status |
|---|---|---|---|---|---|---|
| ZapHub | Auto-farm + auto-quest | Medium | Key system (check compatibility before doing key steps) | Android yes / iOS confirm | Not yet tested — verification pending | Unverified |
| 6FootScripts | All-round cheat menu | Medium | Check hub source | Android yes / iOS confirm | Not yet tested — verification pending | Unverified |
| Reaper Hub | Auto-farm | Medium | Key via hub Discord | Android yes / iOS confirm | Not yet tested — verification pending | Unverified |
| Aussie Studios | Auto-farm + auto-ranker | Medium | Key system (ships executor fallback) | Android yes / iOS confirm | Not yet tested — verification pending | Unverified |
| Zer0 Hub | Mobile-friendly, auto-quest | Light–Medium | Check hub source | Android yes / iOS confirm | Not yet tested — verification pending | Unverified |
Hub status below is community-reported. The site owner verifies each hub against the script library and records the test date, Delta version and result — until then, rows are honestly marked unverified.
Run your first script — zero to working
- Install Delta Executor and get your key — see our Delta key guide. The key lasts 24 hours — this is step zero. Nothing runs without a valid key. (Ignore stale guides that mix executors — one ranking page tells you to “download Delta” then “tap the Hydrogen APK.” Follow this page’s Delta-only flow.)
- Open Roblox through Delta and join Pet Simulator 99. Wait until the world is fully loaded before touching the script hub — running a script during the loading screen commonly causes an instant crash.
- Tap the Delta icon overlay inside the game. The script hub opens: you’ll see a text box (the paste box) and an Execute button.
- Paste the loadstring into the paste box and tap Execute. If the script is large, make sure you’re pasting the short loader version, not the full source — mobile executors can choke on big pastes.
- A hub menu should appear inside the game — that’s success. Start with one feature (auto-farm) before enabling the rest.
- If nothing happens, don’t re-paste blindly — read the “when the script misbehaves” section below.
When the script misbehaves — direct answers
“The GUI loads but nothing happens?”
A missing result doesn’t necessarily mean the script is dead — but in PS99 this exact symptom has a known cause: a game update changed the server paths the script calls, so the client-side menu renders while farm actions silently fail. Re-copy the loader fresh from the hub’s official source, check the hub’s patch-status channel, and give it 24–48 hours after a BIG Games update before assuming worse.
“It says 404 / the raw link is dead?”
The author moved or deleted the repo — the most ordinary death in this niche. Don’t hunt mirrors of the dead link; switch to a maintained hub from the table above.
“None of the executors work anymore — did Roblox ban them all?”
Almost certainly not — this misdiagnosis recurs whenever one executor breaks. It’s usually per-executor breakage (outdated Delta build, or a Roblox client update that broke Delta specifically). Diagnose in order: is Delta outdated, is the script patched, did Roblox just update — before concluding anything about bans.
“Delta crashes during coin farms?”
The documented cause on low-RAM phones is OOM termination during intense farming. Use the hub’s FPS booster/white-screen mode, disable effects, lower graphics, free RAM before launching — and keep overnight expectations modest on budget devices.
“The hub asks for another key — is that normal?”
Yes, and it’s the angriest friction in PS99 comments — including a user warning others “DO NOT WASTE YOUR TIME GETTING A KEY” for a hub that didn’t support their executor. Many hubs run Luarmor, Linkvertise, or Discord-distributed key systems on top of Delta’s 24-hour key. Always check hub-executor compatibility before doing any key steps. Delta’s own key is free — never pay third-party sellers for keys, and never enter your Roblox password to get one.
“The script throws a weird Lua error on Delta?”
Some scripts call advanced executor APIs (debug/closure functions) that Delta mobile doesn’t fully implement — the script’s own author can’t fix that from their side. If you see cryptic errors like invalid-argument failures, the script likely needs a PC executor; pick a Delta-tested hub instead.
The Delta key, explained (it gates everything)
The 24-hour rule: Delta’s free key expires 24 hours after you get it. Key first, scripts second — every single time.
If your key says Invalid, check for a typo or an extra space — always copy-paste, never type it by hand. Users commonly report that switching networks or restarting the phone can expire a key early, so if your key dies unexpectedly, those are the first things to check. (And to be explicit: Delta’s key and a hub’s script key are separate systems. “No key” in a video title means no script key — Delta mobile still needs its own.)
The Linkvertise/Platoboost steps are widely understood to fund the free Delta key system. A legitimate flow never asks you to download extra files mid-task — those pop-up downloads are red herrings; don’t install them.
Key-bypass tools and “no key” videos are a well-known malware vector — researchers and users report them carrying infostealers rather than a working bypass. There is no known safe bypass.
Confused by “no key” PC videos? The key flow on Windows may differ — see the key guide; that’s a platform difference, not a trick you’re missing. Mobile needs the key.
Safety — bans and fake scripts (read this once)
Will you get banned? Possibly, yes. No executor is fully safe — every one violates Roblox’s Terms of Service. BIG Games runs server-side anti-cheat and issues permanent bans for botting, with the highest risk on economy-disrupting behavior: mass diamond farming, duping, and statistically anomalous auto-hatching at scale (one hub FAQ advises reasonable hatch intervals for exactly this reason). Overnight AFK farming is the riskiest routine use. Practical risk reduction: test new scripts on an alt account, keep Delta updated, and use private servers where the game supports them.
A loadstring runs remote code that the author can change at any time — prefer hubs with public source code, and never run a script you can’t inspect. Fair play: auto-accepting “favorable” trades exploits other players — keep trade automation to private servers or accept the social cost.
Roblox support is the place to start if an account is compromised: change the password, sign out of all other sessions, enable 2FA, and review login methods. Note that stolen session cookies can survive a password change, so signing out everywhere matters.
In PS99, the comment section is the attack surface. A hub author pinned a warning on his own ScriptBlox page: “DO NOT TRUST THE PS99 SCRIPTS IN THE COMMENTS BELOW! THEY ARE MAILSTEALERS!” — attackers drop account-stealing scripts disguised as “fixed versions” directly beneath legitimate ones. One user reported a fishing script stealing their exclusives, advising anyone tricked to leave the game immediately. “Anti-stealer” scripts are themselves a trust gamble — one advertised “Anti Mailbox Stealer” drew comments calling it a stealer. And the bait is always too-good-to-be-true: “gem generators,” “dupe diamond,” “all secret pets unlocked,” “trade freeze” videos promise what real scripts can’t deliver, because PS99’s economy is server-side. Test any new script on an alt with no valuable pets first. Most script downloads are merely broken or outdated rather than malicious — but the malicious ones follow these exact patterns, which is why unverified sources aren’t worth the risk.
Red flags — never run anything that: appears in a comment section under a legit script (“fixed version” = mailstealer until proven otherwise) · promises gem generators, dupes, unlocked secret pets, or instant max level · is a “script download” .exe, .zip, or passworded archive (one viral video even instructs disabling antivirus — never) · asks for your Roblox password or cookie. Paste-only loadstrings from GitHub raw links you can inspect; never disable your antivirus for a script.
On iPhone? Read this
Most PS99 scripts are plain Lua and can run on both Android and iOS — but compatibility varies by hub, and obfuscated hubs are specifically noted as less predictable on mobile, so treat iOS support as per-hub, not guaranteed. When nothing runs on an iPhone, the cause is usually Delta iOS itself: Roblox client updates have broken Delta on iOS outright (injection failures, instant crashes on launch), and sideloaded certificates get revoked. Fix Delta first — then re-test the script.
Where to check what’s working right now
Delta Executor Discord #announcements channel is the fastest source for Delta itself after a Roblox patch. This page is updated as hubs change — the status labels in the table are the honest signal: anything unverified stays marked that way until the owner confirms it against the script library. (Expect most hub support and key resets to live inside the hubs’ private Discord servers — this page exists so the public, searchable answers live here too.)
How this page stays accurate
The hub table is maintained against the site’s script library: each hub is checked against its official source in Delta, and where confirmed we record the test date, Delta version and result. If a hub fails verification, its status flips to Unverified and stays that way — visibly — until it passes again. Rows that can’t be verified against an official source are removed rather than left to rot.
