| Evaluation | The llm_judge assertion uses a second LLM call to grade a response and explain its reasoning. | The Evaluator scores prompts, identifies weak areas, and offers guidance to improve them. |
| Integrations | The documented LLM providers are OpenAI and Anthropic, with a fake provider for hardcoded responses. | The privacy policy lists Google, GitHub, and Microsoft as OAuth providers for account authentication. |
| Versioning | Every prompt change creates a numbered version, so existing versions are not overwritten. | Every save creates a prompt version, and users can roll back to an earlier version. |

SpacePrompts
SpacePrompts is a prompt management platform for people and teams working with AI. It runs on the web, through an API, and with Chrome, Edge, and Firefox extensions. Users can save, organize, run, version, and reuse prompts. The Playground combines an editor, variables, model selection, and immediate runs. An Evaluator scores prompts, highlights weak areas, and gives improvement guidance. Every save creates a version that can be restored later. The prompt manager extension can turn highlighted webpage text into a prompt. Its token counter supports OpenAI, Claude, Gemini, and DeepSeek models, showing token counts and estimated costs. Pro and Team plans provide API access, limited to 60 requests per minute per key. Team workspaces add shared libraries, collaborative editing, and role permissions for up to five members. Free includes 50 prompts and daily usage limits; Pro is $5 a month billed annually, and Team is $9 a month billed annually.
