PyCharm Problems & Issues
Real user-reported problems, complaints, and limitations for PyCharm. Based on analysis of 12 signals.
Issues by Category
Extremely high RAM consumption
PyCharm consumes around 1GB of memory idle while VS Code remains under 300MB. Users report memory consumption often topping 1.5GB, with severe cases hitting 12GB. The IDE becomes nearly unusable after a few hours of coding with low memory warnings.
Slow startup and indexing times
PyCharm's slow startup is annoying for users working on big projects. The IDE loads plugins and libraries at startup causing delays. Users on older machines report significantly worse startup performance compared to VS Code.
IDE freezes and lagging issues
Garbage collection causes everything to come to a grinding halt resulting in lagging. Users report PyCharm experiences bottlenecks after a few hours of coding, becoming so slow it's nearly unusable. Very high CPU usage (30-40%) reported.
Disk space bloat from junk files
PyCharm is not lightweight and eats PC space with junk files, requiring weekly cleanup. The IDE accumulates cache and index files that consume significant disk space over time, affecting system performance.
Pro version expensive, Community limited
PyCharm Professional costs $199/year while the free Community edition limits users to Python only with no web framework support. Advanced features like Django, Flask, database tools, and data science features require Pro subscription.
AI features cost extra
JetBrains AI Pro addon costs $100/year for individuals and $200/year for organizations on top of PyCharm Pro subscription. Users expecting AI features included with Pro are surprised by the additional expense.
Cannot open multiple projects simultaneously
The interface does not allow you to have several projects open at the same time, requiring opening several instances. This frustrates developers working on multiple related projects who need to switch contexts frequently.
Steep learning curve
The learning curve is worse than other programs, meaning it takes more time to use properly. The user interface and overall experience could be more intuitive. New users coming from simpler editors struggle with PyCharm's complexity.
File structure sync issues
Newly created files sometimes do not appear in file structures, requiring PyCharm restarts. This disrupts workflow when developers create files outside the IDE or through scripts and don't see them reflected.
False positive warnings in code
In rare occasions PyCharm underlines code with yellow, marking it as an issue when there is no actual issue. This creates confusion and wastes developer time investigating non-existent problems in their code.
New features introduce bugs
Users complain that new features keep being added but problems are never fixed. Minor versions introduce breaking changes and bring the IDEs to a slow crawl. Stability suffers as JetBrains prioritizes features over fixes.
OpenCV and library compatibility issues
The solution does not support some features of OpenCV even though it is part of a PyCharm package. Some third-party libraries have incomplete or broken IDE integration causing missing autocomplete and errors.
Regret Patterns
Common reasons users regret choosing PyCharm.
Paid for Pro when Community would suffice
Users realize after months that they only needed pure Python development without web frameworks or data science features. The $109/year feels wasted when Community edition covers their actual needs.
Memory issues make development frustrating
Developers buy PyCharm expecting smooth IDE experience but encounter constant low memory warnings and freezes. The 1GB+ baseline usage leaves little room for other applications on 8GB systems.
Startup delay kills quick editing workflow
Users accustomed to VS Code instant startup find PyCharm's boot time frustrating for quick edits. They end up using a lighter editor alongside PyCharm anyway, questioning the subscription value.
VS Code caught up for their use case
Long-time PyCharm users discover VS Code with Pylance extension now handles their Python needs adequately. The free alternative makes the Pro subscription feel unnecessary.
Learning curve steeper than expected
Users coming from simpler editors struggle with PyCharm's complexity and many configuration options. The time investment to become proficient exceeds expectations.
AI features require additional payment
Users excited about AI coding assistance discover the JetBrains AI Pro addon costs $100/year extra. The additional expense on top of Pro subscription feels excessive.
When PyCharm Breaks Down
Specific scenarios where PyCharm fails or underperforms.
System has less than 16GB RAM
PyCharm consumes 1GB+ idle and can hit 12GB with large projects. On systems with 8GB total, swapping occurs frequently making the IDE nearly unusable. Users report bottlenecks and freezing after a few hours.
Need quick edits across multiple projects
PyCharm cannot open multiple projects simultaneously without separate instances. The slow startup time makes quick edits impractical, forcing developers to use lighter editors for simple tasks.
Working on non-Python languages
PyCharm focuses exclusively on Python. Projects mixing Python with JavaScript, TypeScript, or other languages require either plugins, separate IDEs, or switching to VS Code which handles polyglot projects natively.
Budget constraints require cutting costs
At $109-299/year per developer, PyCharm Pro licenses add up for teams. When budgets tighten, switching to free VS Code with Pylance becomes obvious. Community edition may lack needed features.
Very large codebase with millions of lines
PyCharm's comprehensive indexing becomes increasingly slow with very large codebases. Memory usage spikes and garbage collection pauses cause lag. Users report the IDE becoming sluggish at scale.
Team standardizes on VS Code
As VS Code becomes industry standard, teams enforce it for consistency and shared configurations. Individual PyCharm subscriptions become wasted cost when team policy requires VS Code.
