SwitchHosts is still the most common free hosts manager. It works. It is open source. It runs on Windows, macOS, and Linux.
People search for a SwitchHosts alternative when something in the daily loop gets annoying: forgotten DNS flush, Electron footprint, or wanting clearer multi-environment switching.
This is a practical comparison, not a takedown.
What SwitchHosts is great at
- Free and open source
- Profiles / groups you can toggle
- Remote hosts lists
- Cross-platform
- Active enough community for a niche tool
If that covers your needs, stay. Free is a real feature.
Why people look elsewhere
1. DNS flush is still your job
Change a profile, refresh the browser, still on the old IP. Classic.
You need an OS flush every time:
# macOS
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
# Windows (Admin)
ipconfig /flushdns
# Linux (systemd-resolved)
sudo resolvectl flush-caches
Tools that flush automatically remove a whole class of "is hosts broken?" mornings.
2. You want stronger backups
A bad paste into hosts can take down local resolution for half your stack. Automatic pre-change backups matter more than people admit until it happens once.
3. You want a lighter or more guided UI
SwitchHosts is capable. Some teams want fewer panels and a clearer "what is active right now?" signal when jumping between client projects.
Alternatives to SwitchHosts
Locahl
Paid one-time desktop app (Windows, macOS, Linux).
Same problem space: manage hosts visually, switch environments. Adds automatic DNS flush and backups.
Pick it if SwitchHosts works but the manual flush / polish gap bothers you enough to pay once.
Terminal profiles
Keep separate hosts files and copy the active one into place. Scriptable. Free.
Pick it if you already live in the shell and do not want another desktop app.
Gas Mask
Mac-only legacy option. Do not migrate to Gas Mask in 2026. Migrate away from it.
iHosts
macOS-focused GUI. Fine for Apple-only setups.
PowerToys Hosts File Editor
Windows-only editor. Good for simple edits, weaker as a full SwitchHosts replacement if you depend on many named profiles.
Hostly (and similar CLI-first tools)
Newer Windows-oriented tools that advertise SwitchHosts import plus a CLI for scripts/CI. Worth a look if automation matters more than a polished cross-platform GUI.

Should you switch?
Stay on SwitchHosts if:
- free / OSS is non-negotiable
- you remember to flush DNS
- profiles already match your workflow
Try an alternative if:
- you lose time to stale DNS every week
- you want safer undo after bad edits
- you share a Win/Mac/Linux team and want one consistent paid tool
Migration tip
Export or copy your SwitchHosts content first. Keep a raw /etc/hosts backup. Import into the new tool. Verify with terminal resolution before you uninstall anything.
ping -c 1 myapp.test
grep -n "myapp.test" /etc/hosts
Same checks you should already run with SwitchHosts.
If automatic DNS flush and backups are the reason you are shopping, look at Locahl as a SwitchHosts alternative. Keep SwitchHosts if free and OSS matter more.
