AI assistants and search decision
Promptweb.Design
A capable developer can reproduce the useful core (a searchable paid prompt directory) in about a week and low monthly cost; the vendor's value-adds (managed integrations and one‑click agent hosting) are the main things you would forgo. Evidence: homepage pricing and feature lines cited below before the judgment section. Evidence from supplied pages: - "Premium Design Prompts for AI Builders." - "$45/mo · all-in" - "Curated for Gemini 3.1 & Opus 4.8" - "Deploy on Telegram, Slack & Discord" - "Run Claude, Gemini or GPT in one click" - "16,000+ app integrations built in" - "Your AI agent, live in 60 seconds"

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Promptweb.Design alternatives, with the arithmetic →
What a replacement has to do
- Browse curated prompts, view and copy a prompt, sign up and subscribe, and submit new prompts (admin upload).
What it still won’t have
- Managed one-click agent deployments to Telegram/Slack/Discord
- Access to vendor-managed integrations ("16,000+ app integrations built in")
- Hosted infrastructure and any backing services bundled with the $45 plan
- Any curated community or editorial curation beyond your initial set
What remains hard
- Product polish and ongoing maintenance

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a small Rails or Next.js + Postgres app deployed to a $20/mo VPS (DigitalOcean). Core features: authenticated user signup/login, a prompt catalog (title, description, tags, model targets), single-prompt view with copy-to-clipboard, full-text search and tag filters, Stripe subscription checkout gating the premium catalog, and an admin-only prompt upload/moderation UI (CSV import). Out of scope: one-click agent deployment to messaging platforms, managed third-party integrations, and training/hosting models. Include error handling, input validation, basic unit tests for API endpoints, and deployment scripts (Docker + simple CI).

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
