Category: Digital Art & IllustrationVerified for 2025
Top Recommended Replacements
Krita
FREEBest Overall Free Alternative
Why we like it
100% free; massive feature set including 2D animation, vector tools, and advanced brush engines; supports non-destructive layers and Python scripting.
Keep in mind
More resource-intensive than SAI; the interface is significantly more complex, mirroring a full-scale IDE or Photoshop.
Clip Studio Paint
Best for Professional Manga & Comics
Why we like it
The industry standard for illustrators; features an unmatched 3D model system for posing; incredible vector-to-raster line handling; massive online asset store.
Keep in mind
The 'Version 3.0' update policy (2024/2025) which requires an 'Update Pass' or subscription for new features has been unpopular with some long-time users.
FireAlpaca
FREEBest Lightweight Free Alternative
Why we like it
Incredibly fast even on low-end hardware; unique tools like the '3D Perspective' and 3D onion skinning; simple, easy-to-learn interface.
Keep in mind
The free version is ad-supported (at startup); brush customization is not as deep as SAI or Krita.
MediBang Paint
FREEBest for Cloud & Manga Teams
Why we like it
Tailor-made for comic artists with free screentones and background assets; built-in team collaboration tools for sharing projects via the cloud.
Keep in mind
The 'Pro' features and ad-removal now require a subscription in late 2025; cloud-dependency can be a hurdle for offline artists.
Procreate
Best for Mobile/iPad
Why we like it
The gold standard for tablet art; industry-leading brush latency; one-time purchase; now includes 'Procreate Dreams' for cinematic animation.
Keep in mind
iPad-exclusive; lacking some of the technical 'Linework' layer precision found in SAI's desktop version.
Sketchbook Pro
FREEBest for Minimalist UX
Why we like it
The cleanest, most focused interface in the category; excellent for quick concept sketching; professional-grade perspective guides.
Keep in mind
Lacks the complex layer masking and specialized 'Watercolor' blending modes that define the 'SAI look'.
