Presets and custom conditions

Presets

Lagsmith includes the same presets as Apple’s Network Link Conditioner, by the same names:

• Edge
• 3G (780 kbps down, 200 ms latency)
• DSL
• LTE
• WiFi
• Very Bad Network
• 100% Loss
• No Throttling: watch the app without changing its network

Each app has its own setting. In the iOS Simulator, you can even set the same app differently on different simulator devices.

Custom conditions

Set download and upload bandwidth, latency, jitter and packet loss, and save them as your own presets.

Profiles

Profiles change conditions over time instead of holding one fixed speed, so you can test a connection that gets worse and recovers.

Host rules

Limit a rule to some hosts, such as only api.example.com, or everything except a CDN.
