In their own words
PromptHub
PromptHub is a community-driven platform for finding, managing, testing, and deploying prompts. Public prompts can be shared with the community; private prompts with teammates are available on paid plans. Git-based versioning tracks prompt changes, and an API supports prompt management and deployment. Evaluations compare outputs across test cases, while pipelines can run checks on commits or merges for secret leaks, profanity, and regressions. Listed model providers include OpenAI, Anthropic, Azure, Google, Meta, Bedrock, and Mistral. Prompts can also be deployed through shareable forms or Zapier. The Free plan includes unlimited public prompts and team members, but not private prompts; it also has 2,000 requests per month and limited API access. Pro costs $12 a month for one user, and Team costs $20 a month per user. Enterprise pricing is custom and not listed. Customers supply their own LLM API keys and pay providers' token costs separately. The pricing page says prompts, variables, and outputs are encrypted at rest and in transit using AES-246, TLSv1.2+, and regularly rotating keys. The company is Tethered Software Inc.
PromptLayer
PromptLayer combines a prompt registry and visual prompt CMS with evaluations, observability, and agent tracing for teams building AI products. Teams can visually edit, version, test, and deploy prompts without waiting for an application redeploy, allowing domain experts and non-technical stakeholders to work alongside engineers. Evaluations can run when prompt versions change, through the API, or on demand in the UI. They include historical backtests and side-by-side model comparisons. Tracking covers requests, traces, cost, latency, token usage, scores, and custom metadata, with OpenTelemetry span support. The OpenAI integration includes versioned prompts, release labels, request observability, evaluations, and model comparisons. Free, Pro, and Team are cloud-hosted in the US; Enterprise offers self-hosting on GCP, AWS, or Azure, EU cloud hosting, or single-tenant cloud hosting. PromptLayer states that it maintains SOC 2 Type 2, HIPAA, GDPR, and CCPA compliance. Free costs nothing, Pro costs $49 a month, and Team costs $500 a month. Enterprise pricing is custom.
