You have three realistic ways to produce Open Graph images: design them by hand (Canva), generate them in code (Vercel OG), or use a dedicated generator (ogimgen). The comparison posts you'll find online mostly stop at price. The decision actually hinges on three questions: how often your cards change, who touches them, and whether the design needs to outlive the person who made it. Here's the honest breakdown.
The Three Approaches
| Criterion | Canva | Vercel OG | ogimgen |
|---|---|---|---|
| Cost | Free tier / Pro ~$12-15/mo | Free (code + hosting) | Free 10 exports / unlimited from ~$9/mo |
| Design control | Full — drag, fonts, brand kit | Code-defined | Template-defined |
| Per-post automation | Manual each time | Automatic — route renders per page | Automatic — feeds titles into templates |
| Non-developer friendly | Yes | No — it's code | Yes |
| Consistency at volume | Depends on discipline | Perfect — same code, same output | Perfect — template enforces it |
| Effort to start | Minutes | An afternoon (see Next.js guide) | Minutes |
When Each One Is the Right Answer
Choose Canva if…
You ship a handful of cards a month, the design matters as much as the content, and a person (you or a designer) is in the loop for every card. Canva's strength is taste: fonts, spacing, brand consistency in a visual editor. Its weakness is repetition — 30 cards a month means 30 manual exports, and the same template drifts between months because humans are doing the spacing.
Choose Vercel OG if…
You're a developer with a dynamic site and every post needs its own card. The route-handler pattern renders 1200×630 cards at request time with the page's real title and data — zero manual steps, perfect consistency. The cost is that the design lives in code, so a non-developer can't tweak the card without opening a pull request.
Choose ogimgen if…
You want automation without code. Feed a title (plus site name and a few fields) into a template, get the card back, and let the pipeline generate cards for every post at once. It sits between the two worlds: template-defined design (consistent like Vercel OG), no coding required (friendly like Canva). It's the right call for blogs and marketing sites where the team is content people, not engineers.
The Free-Tier Fine Print Nobody Quotes
All three options have a "free" answer, and each free tier hides a different tax. Canva's free tier is genuinely capable but exports at lower resolution for some designs and drives you toward the Pro workflow with every new feature. Vercel OG's "free" means you already pay for hosting and someone maintains the code — a real cost if your team has no developer. ogimgen's free 10 exports suit a site that publishes a handful of posts a month; past that, the unlimited tier is where the design work actually starts paying for itself. Whichever row you pick, check the cost against your publishing volume, not against the demo.
Switching Later Is Cheap — Mostly
Moving between the three is easier in one direction than the other. Going from Canva to an automated pipeline means rebuilding your cards as templates — a one-time design transfer. Going from a tool to Canva means every future card is manual. If you suspect your volume will grow, start closer to the automated end; the other direction is a habit change, not an export step.
The Decision Flow
- Do cards need to change per post? No → Canva once, reuse everywhere.
- Per-post cards, and you can write code? → Vercel OG.
- Per-post cards, no coding wanted? → ogimgen.
Every comparison that skips these questions is selling you a tool instead of a workflow. Whatever you pick, the output must be 1200×630 with a safe center band — the size guide has the geometry so your cards survive every platform's crop.
