01 · EDIT
Pick an environment
Named environments per client or per project. Toggle an entry instead of commenting a block.
Hosts file manager · macOS · Windows · Linux
The hosts file manager whose changes actually take effect.
Edit your hosts file in a real interface, hit Apply, and the system and browser DNS caches are flushed for you. The change takes effect on the first reload.

02 · CHECK
Read the diff
Invalid IPs and domains are refused before the write. You see the exact lines that will change.
03 · APPLY
Snapshot, then write
A backup is taken first, so a bad edit is one click from being undone.
04 · FLUSH
Caches cleared · 0.4 s
System resolver and your configured browsers. The first reload shows the new IP.
Why not just edit the file
Your edit was right.
The cache was lying.
The system resolver and every browser keep their own cache. Save the file and both keep answering with the old IP, which is where the lost hour goes, debugging code that was never broken.
SwitchHosts and Gas Mask write the file too, and if a free editor covers your need, take it. The difference is everything that happens after you hit save.
