Free hosts file editor alternatives: SwitchHosts, PowerToys, Terminal, and when to pay

#devops #tutorial #productivity #webdev

You can manage the hosts file without paying anyone. Plenty of people should.

This is the free stack, plus the one case where a one-time paid app is rational.

Free options that actually work

1. SwitchHosts

Best free GUI for most developers.

  • Win / Mac / Linux
  • Profiles and groups
  • Open source

Cost of free: flush DNS yourself; live with the Electron-style desktop footprint.

2. PowerToys Hosts File Editor (Windows)

Best free "just edit the file" tool on Windows if PowerToys is already installed.

Cost of free: weak multi-environment story, Windows only.

3. Terminal / text editor + sudo

Best free option for people who already script their machines.

sudo nano /etc/hosts
# then flush DNS for your OS
Enter fullscreen mode Exit fullscreen mode

Or keep profile files and copy them into place.

Cost of free: no seatbelts unless you add backups and checks.

4. Built-in Notepad / TextEdit (elevated)

Works. Painful. Easy to edit a copy that is not the system file.

Use only for rare one-line changes.

5. Gas Mask

Free historically. Not a free recommendation in 2026. Unmaintained.

Paid option worth mentioning

Locahl

Not free. One-time purchase. Cross-platform.

You pay for automatic DNS flush, backups, and a more guided multi-environment UI.

Pay only if the free tools are costing you real time (stale DNS, broken hosts, no shared OS story).

Free vs paid decision

Stay free if:

  • you edit hosts weekly or less
  • you remember DNS flush
  • OSS or zero budget is the rule

Consider paid if:

  • you switch environments daily
  • teammates keep hitting Permission denied / stale cache
  • you want one tool on Windows, macOS, and Linux

Suggested free setups

Solo, mixed OS, free only

SwitchHosts + a shell alias for DNS flush.

Windows-only, rare edits

PowerToys Hosts + ipconfig /flushdns.

Power users

~/hosts-profiles/local
~/hosts-profiles/staging
./hosts-use <name>   # copies + flushes
Enter fullscreen mode Exit fullscreen mode

Do not confuse "free editor" with "safe workflow"

Every free path still needs:

  1. Backup before big edits
  2. One active mapping per hostname
  3. DNS flush after apply
  4. Terminal verification before blaming the app

Those four steps matter more than the logo on the window.

Free default: SwitchHosts. If free is costing you time on flush and backups, Locahl is the paid cross-platform alternative.
