Cardsmith and Bannerbear solve the same problem from opposite directions: one is source-available software you can own outright for $39, the other is a subscription at $49/mo run entirely on someone else's servers.

What Cardsmith does well
- Visual template editor — Canvas with drag positioning + snap guides, layers panel, and a live preview that matches server output pixel-for-pixel.
- Layer types — Text (bundled fonts, weight, align, wrap, auto-shrink to fit), images (upload or URL, cover/contain/fill, radius, opacity), shapes and solid/gradient/image backgrounds.
- Sizes for every network — OG/blog 1200×630, X large card 1600×900, Instagram 1080×1080 and 1080×1920 story, LinkedIn 1200×627 — plus fully custom dimensions.
- {{variables}} — Type {{title}} in any text layer (or image URL) and the template instantly becomes an API endpoint with that parameter.
What Bannerbear still does better
There's a real reason Bannerbear costs what it does: a bigger team, broader integrations and dedicated support behind it. If that ecosystem is genuinely what you need, it's worth paying for.
Which one should you pick
If your workflow depends on Bannerbear's specific integrations or you'd rather not run anything yourself, stay put — that's a legitimate call. If you're comfortable owning the tool and want to stop paying $49/mo for a job your own hardware can do, Cardsmith pays for itself and then some: cardsmith costs less than a single month of Bannerbear — it pays for itself in 24 days.
