## PromptLayer

PromptLayer targets the gap between prototyping with an LLM API and running that application reliably in production. It packages the tooling teams usually end up building themselves: a prompt registry, a visual CMS for editing and versioning prompts, an evaluation harness, and an observability stack that ties production traffic back to the prompt versions that generated it.

The core insight is that prompt quality is a product concern, not only an engineering one. Because prompts live in a dashboard rather than scattered through a codebase, domain experts — product managers, marketers, curriculum designers, support leads — can edit and test them directly, while engineers keep control over what actually ships. Version history, diffs, comments and rollbacks keep that collaboration auditable.

Evidence comes from evaluation and production. Teams define datasets, run automated and human grading, set up regression tests that fire whenever a prompt changes, and backtest new versions against historical data. In production, traces connect each request to its prompt version, so quality, cost and latency can be compared side by side. Agent workflows get the same treatment: prompts, tool calls, evaluations and logs stay in one place for multi-step runs.

**Pricing & Plans:** PromptLayer has a free tier and three paid tiers. Free is $0/month with 5 users, 2.5k requests per month, 1 workspace, 250 eval cell executions and 10MB datasets. Pro is $49/month and adds unlimited playgrounds, unlimited workspaces and 150MB datasets. Team is $500/month with 25 users, 100k+ requests, 7.5k+ eval cell executions and 1GB datasets. Enterprise offers custom limits plus RBAC, deployment approvals, HIPAA with BAA, self-hosted or EU hosting and dedicated support. Overage is billed per transaction (about $0.003 on Pro, $0.002 on Team).

- **No-code visual prompt CMS:** Edit, version, diff and roll back prompts from a visual dashboard with no coding, so product, marketing and content teams can iterate on prompts while engineers keep control of the deploy.
- **Evaluations and regression testing:** Run dataset-backed tests with human and AI graders, trigger regression evals whenever a prompt changes, backtest new versions against historical data and compare prompts across models.
- **Observability and tracing:** Connect production traces to the exact prompt version that produced them and inspect failures, cost, latency and token usage by feature, model or user.
- **Agent workflow support:** Build, trace and improve agent workflows with prompts, tool calls, evaluations and logs in one place, so multi-step runs can be tested before they ship.
- **A/B testing and usage analytics:** Release new prompt versions gradually, compare live metrics, and see exactly how the LLM application is being used, by whom and how often, without jumping to a separate analytics tool.

**Limitations:** Team plan jumps to $500/month, which is steep for small teams that outgrow Pro; Usage beyond plan limits is billed per transaction, so heavy LLM traffic needs forecasting; Role-based access controls, deployment approvals and SSO are Enterprise-only; Live in the developer ecosystem, so setup expects an LLM API and engineering involvement

## Skillry

Skillry is a curated library of Agent Skills — reusable packages of instructions, templates and scripts that AI coding agents can install and run. The concept is straightforward: give an agent a well-designed workflow, and it can produce a complete, presentable artifact rather than a rough draft. Skillry focuses on deliverables you would actually show, spanning web pages and landing pages, slide decks, images such as OG graphics, and short videos.

The key differentiator is that Skillry designs the output first. Its team art-directs a finished piece — a page, a deck, a film — then writes the original instructions, templates and scripts that let your agent reproduce that style. Each Skill page displays a real result it made, so you can see the visual point of view before installing. Skills are maintained by the same team as agents and models evolve.

Installation is agent-first. You can browse the catalog on the web, connect via MCP so your agent can search and inspect Skills, or install from the CLI. Free Skills require only a sign-in, while Premium Skills come with a Pro subscription or a one-time lifetime purchase. Model, API and rendering costs are handled by your own environment, not by Skillry.

**Pricing & Plans:** Free Skills are available with a sign-in. Pro is $9.99/month (regularly $19.90) or $79/year (regularly $158), and a Founding Lifetime plan costs $169 one-time. All paid plans include Premium Skills, MCP/CLI/web install and ongoing updates; model and rendering costs are extra.

- **Original in-house Skills:** Every Skill is designed, written and tested by the Skillry team, with templates and scripts built from a finished piece of work.
- **Multiple output types:** Skills cover web pages, slide decks, images, video and reports, so your agent can produce a range of assets.
- **Broad agent support:** Install and run Skills inside Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI and more.
- **Preview before install:** Each Skill page shows a real result it generated, so you can judge the visual style before adding it.
- **Flexible installation:** Add Skills from the web, through an MCP connection or from your CLI, with browser-based authorization.

**Strengths:** Original Skills designed and maintained in-house; Covers websites, slides, images and video in one library; Works across Claude Code, Codex, Cursor and many other agents; Each Skill previews a real result before you install

**Limitations:** Full access to Premium Skills requires a paid plan; Model, API and rendering costs are separate from the subscription; The catalog is newest to market, so coverage keeps evolving
