The IB API must use an Access Method (either TWS or the IB Gateway) before it can connect to the IB trading system through one of the available Connection Types described below.
If you prefer quick access to the latest production version, log in to the browser-based TWS or IB Gateway, which you access from the Login command on the menu above. If you prefer to upgrade manually to ensure that your API works with a specific version of TWS or the IB Gateway, download the standalone version(s) below to your desktop.
| Windows | Mac | UNIX |
| IB Gateway for Windows | IB Gateway for Mac | IB Gateway for UNIX |
| Browser-Based | |
| Browser Based IB Gateway | Browser Based IB Gateway Beta |
You can log into either interface at any time with no repercussions. You may want to use TWS for testing, and subsequently run the IB Gateway to conserve system resources. Both access methods are upgraded synchronously and provide the same features; the primary difference is that the IB Gateway has no graphical user interface (GUI).
| Feature | TWS | IB Gateway |
| Provides a GUI that allows you to see and manage API orders. | Yes | No |
| Must remain running to maintain access to IB trading system. | Yes | Yes |

| GUI-less interface runs more efficiently and uses fewer system resources. | No | Yes |
Only one type of connection may be used for each account (account types with multiple accounts, such as advisors, may only have one connection type for all accounts). Switches in connection type can take up to a week.
| Connection Type | Access Method Required? |
