Hotfix vs. Bugfix: What's the Difference?
A hotfix is an urgent update to fix a critical issue in software without disrupting its operation, while a bugfix addresses a general software error or flaw, often in regular updates.
Hotfixes are implemented quickly to address critical, often operational, issues in live systems. Bugfixes, conversely, are routine fixes for identified errors in software, typically part of scheduled updates.
Hotfixes are designed to be minimal and non-disruptive, targeting a specific problem. Bugfixes can be more comprehensive, addressing various bugs in a single update.
The urgency of a hotfix is usually due to security vulnerabilities or major functionality issues. Bugfixes, while important, may not always address immediate threats or critical breakdowns.
Hotfixes are applied to live environments, often without requiring system restarts. Bugfixes are typically part of a planned update cycle and may necessitate downtime or reboots.
In terms of deployment, hotfixes are usually temporary and quickly replaced by more permanent solutions. Bugfixes, in contrast, are permanent improvements to the software’s codebase.
High, for critical issues
Lower, for routine errors
Immediate, in live systems
Scheduled in regular updates
Minimal, often no restarts required
May require downtime or reboots
Specific, targeting one issue
Can be broader, fixing multiple bugs
Often temporary until a full update
Permanent codebase improvements
