Placard is a free OG image generator with a live 1200×630 preview and a dynamic image API: one URL per card, query params in, og:image out. 8 templates, edge-cached, from $0.
The live preview is genuinely handy, no guessing how it'll look at 1200x630. Query param API approach feels cleaner than most generators I've tried.
How does the dynamic API handle caching invalidation if I want to update an image but keep the same URL?
How does the dynamic image API handle caching when I update the template design, will the old URLs immediately reflect the new look or do they stick to the first render?
The query-param API idea is genuinely clever, turning a static preview tool into something you can actually embed in a build pipeline. Love that it stays free and edge-cached instead of gating the useful part behind a paywall.
The live 1200x630 preview while tweaking params is such a nice touch, no guessing what the final card will look like. The single-URL API approach feels really well thought out too.
