Atom Problems & Issues
Real user-reported problems, complaints, and limitations for Atom. Based on analysis of 12 signals.
Issues by Category
DISCONTINUED - No longer maintained
GitHub officially discontinued Atom on December 15, 2022. The editor receives no updates, no security patches, and no support. All Atom repositories were archived. Using Atom in 2024+ is strongly discouraged.
Dependencies and ecosystem abandoned
The Atom package ecosystem is abandoned. Package authors have moved on, packages are unmaintained, and compatibility issues with modern systems will only grow.
Not compatible with future OS updates
Without active development, Atom will eventually become incompatible with new operating system versions. Apple Silicon, Windows updates, and Linux distributions may break functionality.
Packages break the editor frequently
Add-ons can ruin the experience, with packages weighing it down to the point of freezing. Extensions break the editor frequently, yet it is nearly useless without extensions.
Thousands of unresolved issues
GitHub faced over 4,000 open issues when Atom reached 1 million users. Many bugs were never fixed before discontinuation and remain permanently unresolved.
Frequent freezing and performance issues
The top support issue was 'Atom keeps freezing' and the most-discussed issue was 'Why is Atom so slow?' The editor freezes when opening files with long lines and crashes with large files.
High resource consumption for a text editor
Atom's use of Electron and Node.js results in relatively high system resource consumption for a text editor. Memory usage was significantly higher than native alternatives like Sublime Text.
No support available
With GitHub discontinuing Atom, there is no official support, bug fixes, or issue tracking. Community support is minimal. Users encountering problems have no recourse.
GitHub recommends migrating away
GitHub officially recommends users migrate to VS Code or other editors. Continuing to use Atom is explicitly discouraged by its creator.
Contains unpatched security vulnerabilities
The final release v1.64.0 (November 2022) contains unpatched vulnerabilities. With no security updates, using Atom exposes users to known security risks that will never be fixed.
Extension documentation was poor
Documentation on most extensions was described as pitiful. Users struggled to configure and troubleshoot packages due to inadequate documentation.
Slow startup compared to alternatives
Atom's Electron-based architecture resulted in slower startup times compared to native editors like Sublime Text or even VS Code. Cold starts were particularly problematic.
Regret Patterns
Common reasons users regret choosing Atom.
Used discontinued software
Users who continued using Atom after December 2022 found themselves on abandoned software. Migration became necessary when OS updates broke functionality or security audits flagged vulnerabilities.
Delayed migration until forced
Users who procrastinated migration found their Atom setups breaking with OS updates. The longer they waited, the more painful migration became as they had to relearn new editor workflows.
Package ecosystem collapsed
Users dependent on specific Atom packages found them unmaintained and breaking. With no package updates and authors moving on, workflows dependent on packages fell apart.
Security audit flagged Atom usage
Enterprise users faced security audits identifying Atom as vulnerable software. Organizations had to urgently migrate entire teams to supported alternatives.
Should have learned VS Code earlier
Users who finally migrated to VS Code realized they should have switched sooner. VS Code's features, performance, and ecosystem were superior to what they had with Atom.
Lost customizations during forced migration
Users with heavily customized Atom setups lost their configurations when forced to migrate. Many Atom packages had no VS Code equivalents, requiring workflow changes.
When Atom Breaks Down
Specific scenarios where Atom fails or underperforms.
Operating system update
macOS, Windows, or Linux updates may break Atom functionality. With no developers to fix compatibility issues, the editor becomes unusable on updated systems.
Security vulnerability discovered
New security vulnerabilities in Atom's dependencies or core will never be patched. Using Atom becomes increasingly risky as more vulnerabilities are discovered.
Enterprise security audit
Security audits flag Atom as unsupported software with known vulnerabilities. Organizations must migrate teams immediately to pass compliance requirements.
Package dependencies break
Node.js and Electron dependencies become incompatible with modern systems. Packages stop working as their dependencies are no longer supported.
New programming language needed
Atom will never get support for new programming languages or framework versions. Language servers and syntax highlighting for new tech won't be available.
Team standardizes on supported editor
Teams standardizing on VS Code or other supported editors leave individual Atom users behind. Collaboration and shared configurations require migration.
