How to edit an SVG without Illustrator, and what editors change in the file

An article on DEV Community explains that SVG files can be edited with a browser tool, Inkscape, or a plain text editor, without Adobe Illustrator. It recommends the browser-based editor SVG Lab for quick colour and text changes, with no install or account needed for editing. In a test, changing a shape's fill and a text label worked, but the editor also rewrote the markup, removing element ids and altering how circles and text were encoded. The author warns that such changes can break CSS or scripts that depend on those ids, so the file should be diffed before shipping. Inkscape is suggested for longer or print-oriented work, and the piece notes that SVG Lab's exports are limited on the free tier.
