About

ChartBytes renders bar, horizontal bar, stacked bar, pie and donut charts as PNG or SVG from a single URL. Charts are generated server-side, so a plain img tag or Markdown image works anywhere that cannot run JavaScript — email clients, GitHub READMEs, Notion, Slack and PDF reports. Free tier: 500 renders/month with no watermark and no account. Pro: one-time $9 for dark and brand themes, 25,000 renders/month and immutable caching.
