Inkscape

Inkscape is a free, open-source vector graphics editor that uses SVG as its native file format — not an export option, but the actual working file — making it the only major vector tool whose output is web-standard code. Its feature set now genuinely rivals Illustrator: bezier tools, boolean operations, bitmap tracing via Potrace, a Shape Builder tool (added in v1.3), and advanced typography. No subscription, no AI upsell, no file hostage-taking.
