## Open Apps

Open Apps is built around a simple complaint: teams pay a recurring "SaaS tax" for tools that open-source projects already cover, but choosing an open-source replacement is risky because maintenance, code quality and dependency problems are hard to assess quickly. Its answer is a scoring system. Every app and package gets three independent ratings — repo health pulled from GitHub signals such as activity, maintenance and momentum; a separate technical score covering architecture, code quality and learning curve; and a dependency-health score that examines staleness, footprint and known vulnerabilities via OSV.dev.

The directory covers roughly 735 curated apps and thousands of packages, and maps 251 commercial SaaS products to open-source alternatives. Categories span developer tools, AI development and AI agents, databases, DevOps, monitoring, analytics, CMS, CRM, project management and more. Each app page links the project to its category and the alternatives it can replace, and the site publishes its methodology so the scoring can be audited and repeated.

Beyond the catalogue, Open Apps runs research reports and an insights section with aggregate data such as total GitHub stars and contributors, a blog of open-source takes, and an optional paid stack-audit service that recommends what a company could migrate and what it would cost. It is an independent project — not affiliated with the vendors listed — funded partly through community support.

**Pricing & Plans:** Free to browse. The app and package directory, category pages, alternatives pages, research reports and blog are all publicly accessible without an account. A separate paid advisory service (stack audit) is available for companies that want a migration roadmap, and the site invites optional coffee donations.

- **Three disclosed scores per app:** Every app and package receives independent repo-health, technical and dependency-health ratings with a published methodology.
- **SaaS alternative mapping:** Browse by the commercial product you want to replace — Notion, Firebase, Vercel, Slack, Salesforce and hundreds more.
- **Broad category coverage:** Developer tools, AI development and agents, databases, DevOps, monitoring, analytics, CMS, CRM, productivity and dozens of other categories.
- **Research and insights:** Original reports plus aggregate data on GitHub stars, contributors and how many SaaS products the catalogue replaces.
- **Stack audit service:** An optional paid engagement that audits a company's software spend and returns a prioritised replacement roadmap.

**Strengths:** Scores are disclosed and methodology is published, unlike star-count rankings; Covers both apps and lower-level packages, including dependency risk; Free to browse with no account required; Includes original research and an optional advisory service

**Limitations:** Selection is curated, so niche or very new projects may not appear; Scores are the site's own model and should be combined with hands-on testing; A bot-check page can appear for automated traffic, which may confuse some visitors

## PromptBase

PromptBase occupies the 'prompt layer' of the AI stack. As generative models became widely available, the hard part shifted from access to knowing what to type, and PromptBase turned that gap into a marketplace. Buyers get tested wording that reliably produces a particular result; sellers get paid for prompt engineering work they would otherwise give away.

The catalogue is broad rather than deep in any single niche. There are categories for art styles, portraits, product shots, logos, icons, apparel designs, marketing copy and even prompts intended to help build small apps or landing pages. Each listing is tied to a specific model family, which matters because a prompt tuned for one image model often behaves differently in another.

As a marketplace, PromptBase's value depends on its community. Sellers are incentivised by revenue share, which keeps fresh prompts coming, while buyers rely on sample images and seller reputation to judge quality before purchasing. The model is paid rather than free, and the site runs behind standard bot protection.

**Pricing & Plans:** Paid marketplace. Most prompts are sold individually at low per-item prices set by their creators, with subscription options available for buyers who want ongoing access or credits. Pricing is not disclosed on the public page and may vary by listing.

- **Curated prompt catalogue:** Thousands of ready-to-use prompts organised by model and by output type, from illustration styles to marketing copy.
- **Model-specific sections:** Listings are grouped by the model they were built for, so you can filter to the tool you actually use.
- **Sample output previews:** Each prompt is shown with example outputs, making it easy to judge the style before spending anything.
- **Creator seller programme:** Anyone can upload prompts for sale and earn revenue share on every copy sold.
- **Pay-per-prompt or subscribe:** Low per-prompt pricing plus buyer subscription options cover both occasional and high-volume users.

**Strengths:** Saves time you would otherwise spend on trial-and-error prompt writing.; Sample images make quality easier to judge before buying.; Organised by model, so findings map to the tools you already use.; Creators can monetise prompt work directly.

**Limitations:** There is no free tier for buying prompts - you pay per prompt or subscribe.; Quality and usefulness vary between sellers, so results depend on the individual listing.; A prompt that works well in one model is not guaranteed to behave identically elsewhere.; Popular prompts are widely sold, so exclusivity is limited.
