Should I vibe code
Compose fixed-size social graphics from local images, text, and a small template set

Our verdict, the regret score and everything below it. Editorial and unsponsored — nobody can pay to be moved.
The honest answer
why the verdict is what it is
Notice what Snappa deliberately does not do. No freeform canvas, no print production, no brand-kit committee — you pick a fixed size, put a photo behind some text, export a PNG. That constraint is why this lands green where Canva and Piktochart do not, because the honest homemade version is not an editor at all. It is an HTML template and a headless renderer, and on the job people actually do with this class of tool that version is better: it batches, it lives in git, it produces the same pixels twice, and it can generate two hundred variants while you make coffee. What it does not come with is the thing the $15 is really buying — five million stock photos and two hundred typefaces with the commercial licence already sorted, and a background remover that works on hair. That is the whole product, and it is also the only way this build bites you: a face you grabbed off a free-fonts aggregator, rendered by a server, into a client's paid advert.
What actually breaks
not "if". the specific failures.
- Font licensing. A desktop licence covers the machine you designed on, not a render server producing commercial images for a client, and "free for personal use" is the default state of most of what you will download
- Stock imagery that arrived via a search result rather than a licence, which is fine until the graphic is in a paid ad and someone with a reverse-image-search subscription notices
- Text layout. The headline that fits in English overflows in German, and the moment you add batch mode nobody is looking at the output
- Platform dimensions, which change without an announcement, so last year's 1200×628 is this year's centre crop with your logo cut in half
- Glyph coverage on the render box — emoji, Cyrillic and CJK come out as tofu because the container has no fonts installed, and it renders happily rather than failing
- Colour. A headless browser screenshot with no colour profile attached looks noticeably different from what you designed, on exactly the phone screens your audience uses
Is that you?
the verdict is a default, not a law
- Every asset in the pipeline has a licence you could produce if asked
- What you actually want is two hundred variants of one card, not a design tool
- A human sees the render before it is posted anywhere
- The graphics go on your own channels and can be replaced by re-running the script
- The fonts and photos came from wherever the first search result was
- Non-designers on your team will use it and expect to drag things around
- It renders and publishes in one step, with no preview between the template change and the audience
- You are trying to replace a design tool rather than a repetitive export
If you build it anyway
the checklist, then the prompt that enforces it
- Keep a licence file beside the assets: source URL, licence name, date acquired, and whether it covers server-side rendering. Do this on day one, because reconstructing it later is impossible.
- Use fonts with an explicit web or server licence — the open families cover almost everything and remove the entire question.
- Install and pin fonts inside the render container. A missing glyph should fail the build, not silently emit a box.
- Assert that text fits. Measure the rendered line box and error on overflow rather than shipping a headline clipped mid-word to four hundred people.
- Treat platform dimensions as dated config, not constants, and re-check them the same day you re-check anything else.
- Always produce a preview a human approves before anything is published, especially once batch mode exists.
I am building a template-driven social graphic generator: fixed canvas sizes,
an image, some text, export PNG. Constrain it as follows and argue with me if I
ask you to relax something.
1. Do not build a freeform canvas editor. Templates are code — HTML/CSS or a
declarative layout file — rendered headlessly. That is the whole design.
2. Before any rendering, create an assets manifest: every font and image gets a
source URL, a licence name and a note on whether it permits server-side
rendering for commercial use. Refuse to render an asset missing an entry.
3. Only use font families with an explicit open or server licence. If I paste
in a font from somewhere else, stop and ask me where the licence is.
4. Install fonts into the render container explicitly and pin the versions. A
missing glyph must throw, not render a tofu box.
5. Measure text after layout and fail the render on overflow or clipping.
Silent truncation is the failure mode that reaches an audience.
6. Output dimensions live in a dated config file with a comment saying when
each was last verified against the platform's own docs.
7. Set an explicit sRGB colour profile on export and write a test comparing
two runs of the same template byte-for-byte. Determinism is the reason to
build this instead of buying it.
8. Batch mode comes last, and it writes files to a review directory. Do not
wire rendering directly to any publishing API.
9. Strip EXIF, including GPS, from any photo I supply before compositing.
10. Out of scope, and say so instead of half-building: a stock photo search, a
background remover, drag-and-drop editing and a template marketplace. If I
want those, $15 a month buys a licensed library I cannot assemble myself.That one keeps you out of trouble. For the prompt that actually builds it, canivibecodeit.com has one.

the boring option, and the way back out
If the reason you open a graphics tool is to find a photo, pay the $15. Snappa's Pro tier is essentially a licensed asset library with a compositor attached, and assembling the licensed half yourself costs far more than $180 a year in both money and attention. Build your own when the job is repetitive rather than creative — the same card in forty languages, an image per blog post, a chart card generated from data every Monday.
$15/mo is cheaper than your weekend.
Trivial, and that is a feature. Templates are text, renders are PNG files, and the only thing that would trap you is putting the source images somewhere you cannot get them back from. Keep originals and the licence manifest in the same repo as the templates, and the project can be abandoned on any Tuesday with nothing to migrate.
Turns HTML and CSS into SVG, which is the shortest honest path from a template to a fixed-size social image.
The canvas object model most browser-based graphic editors are built on, if you insist on an interactive editor.
Questions
Why is this green when the Canva entry is not?
Scope. Canva is a general design tool with print production, brand kits, video and a marketplace, and rebuilding it is a multi-year canvas project. Snappa is a fixed-size compositor, and the fixed size is what lets you skip the canvas entirely and render from a template. Same category, completely different amount of software.
Is the font thing really a risk or is that lawyer-brain?
It is the one part of this that has ever produced an invoice. Foundries do send letters, the licence you clicked through almost certainly said desktop rather than server, and "free for personal use" describes a large share of what a search returns. The fix costs nothing: use families with an explicit open licence and write down where each came from.
What does the paid product do that my script will not?
Find you a photo. The five million licensed images, the vector library and the one-click background remover are the actual value, and none of them are things you can produce on a weekend. If your bottleneck is sourcing rather than composing, buying is the correct answer and building is a hobby.
Every week, someone ships something they shouldn’t have.
