We make one of these, so read this with that in mind. It's still worth writing honestly — including the part where the other one is the better choice.
These tools aren't really competing for the same job. FoE-Extender automates broadly across the whole game — GvG, Guild Battlegrounds, tavern buffs, unit presets, the routine clicking that fills an evening. SentryFoE does one part of the game thoroughly: Guild Battlegrounds, plus Great Building sniping.
GvG, tavern, city routine, unit presets — the breadth is the product, and SentryFoE genuinely doesn't do any of it. One tool, one subscription, most of the clicking gone.
Attrition-aware target ranking, strikes timed to the second a sector unlocks, army refilled between fights, and remote control from a dashboard. Depth in one place instead of coverage everywhere.
If you want both breadth and GbG depth, be aware that running two bots against the same game client is a bad idea — see the FAQ at the bottom for why.
| FoE-Extender | SentryFoE | |
|---|---|---|
| Scope | Whole game — GvG, GbG, tavern, unit presets, routine actions | Guild Battlegrounds and Great Building sniping only |
| GbG targeting | Battle automation included as one of many modules | Ranks by conquest progress, then attrition, then VP; guild ignore/focus flags respected |
| Sector timing | Not something we can speak to | Parks on a locked sector and strikes on the boundary, synced to server time |
| Remote control | Not something we can speak to | Start/stop and live stats from the dashboard (Pro add-on) |
| Install | Unpacked extension, ZIP from GitHub | Unpacked extension, built per-account from your dashboard |
| Updating | Re-download the ZIP, unzip over the old folder, reload the extension, refresh the game | Rebuild from the dashboard; the panel flags when your build is behind |
| Browser permissions | storage, cookies, unlimitedStorage, system.storage, system.cpu, system.memory, system.display | storage, plus named hosts |
| Licensing | Account on their site, subscription tiers | Account here, one licensed device at a time |
| Against FoE's rules | Yes. Their README says "use it at your own risk"; their home page says "you can use it safely" | Yes, stated plainly — no safety claim anywhere |
| Detection claim | "Disables all game checks for bots" — see below | None. Detection is server-side; nothing in a browser turns it off |
Two rows say "not something we can speak to" on purpose. We haven't run their tool against a live account, and inventing limitations for a competitor would make everything else on this page worth less. If those features matter to you, ask them.
This is the one real disagreement between us, and it's worth being precise about because it's the claim most likely to cost someone their account. As of September 2026, FoE-Extender's home page says, under a heading reading "Udetectable":
"FoE Extender disables all game checks for bots, so you can use it safely!"
A browser extension cannot do that, and the reason is structural rather than a matter of how well it's written. Anti-bot checks that matter don't run in your browser — they run on InnoGames' servers, looking at the stream of actions your account sends: intervals between fights, session lengths, sustained throughput, activity at 4am every night. Code running inside your tab has no reach into any of that. It can't switch off analysis happening on someone else's infrastructure.
To be fair to them about what might be meant: the game client almost certainly does run local integrity checks, and defeating those is plausible. But that is a much narrower claim than "you can use it safely," and the gap between the two is where accounts are lost. It's also worth noting their own GitHub README ends with "Remember: Use it at your own risk!" — which is the honest version of the same sentence, and contradicts the sales page.
We'd rather lose the sale than match that claim. Our position is on what actually gets accounts caught: automation is against the rules, detection is behavioural, and the biggest factor is how you run it — not which tool you bought. If undetectability is what you're shopping for, nobody can sell it to you.
That row looks damning at a glance, so it deserves context rather than a raised eyebrow. There's an obvious legitimate reason for it: reading CPU, memory and display characteristics is a standard way to fingerprint a machine, and a subscription tool needs some way to tell one device from another. That's very likely all it is.
It's still a real difference worth knowing about, because permissions are the one part of any extension you can audit yourself in thirty seconds. Open chrome://extensions, click Details on anything you've installed, and read what it asked for. Do that with ours too — the answer should be storage and the specific sites it talks to, nothing about your hardware.
The differences above are real but small next to what these tools have in common:
If you're deciding whether to automate at all, that shared list matters far more than which panel you prefer. What actually gets accounts caught covers it properly.
Neither of these is a safe choice — only a choice between two tools that both violate the game's rules. If your account is one you couldn't stand to lose, the right answer isn't either product. See our Terms & risk disclosure.
If you've landed here because the clicking is tedious but you'd rather not risk the account, there's a whole category we've both skipped past: read-only helpers. Tools like FoE Helper display information — Great Building calculators, city planners, stat overlays — without ever acting for you.
They're a different proposition under the rules, because you still make every decision and every click. That's a genuine option, and for a lot of players it's the better one. We'd rather say so than pretend the choice is only between us and FoE-Extender.
Breadth versus depth. FoE-Extender automates across the whole game — GvG, Guild Battlegrounds, tavern, unit presets and more. SentryFoE concentrates on Guild Battlegrounds, plus Great Building sniping, and goes deeper in that one area: attrition-aware targeting, timed strikes on locked sectors, and army refill between fights.
Neither, in general — they answer different questions. If you want one tool covering routine actions across the whole game, FoE-Extender's scope is wider and SentryFoE simply doesn't do those things. If Guild Battlegrounds is the part you actually care about, SentryFoE goes deeper there.
Their site says it "disables all game checks for bots, so you can use it safely." No browser extension can do that — the checks that matter run on InnoGames' servers, analysing your account's behaviour, and code in your tab can't reach them. Their own GitHub README says "use it at your own risk," which contradicts the sales page. Both tools break the Terms of Service and both can get an account banned.
FoE-Extender is distributed as a ZIP from GitHub: you download the archive, unzip it over your existing folder, reload the extension and refresh the game. SentryFoE builds a fresh copy from your dashboard, and the in-game panel tells you when the version you're running is behind. Both are unpacked installs, because Chrome's Web Store doesn't accept either category of tool.
Technically nothing stops you loading both, but we wouldn't recommend it. Two tools driving the same game client can act on the same fight at once, and a doubled action rate is exactly the inhuman pattern that gets accounts flagged.
Comparison written against FoE-Extender 1.0.2, its GitHub README, and foe-extender.com as they read in September 2026 — the quoted claim above is theirs, verbatim, on that date. They ship updates and edit their site independently of us, so features, pricing and wording may have moved on since; check the source rather than trusting a competitor's summary of it.
