What is Difference between Salesforce Triggers and Workflows?

Hi sushant,

1. Workflows are part of standard salesforce customisation, so no code is required. While triggers are a piece of APEX code .
2. Workflows only work on record creation and updation, while triggers can work on any DML event.
3. Workflows events include field updates, email alerts, new tasks and outgoing messages only.
4. You can not create records with workflows, while with triggers you can.

There are plenty more differences, for more information go to,
