In their own words
Impromptо
Impromptо provides PromptOps infrastructure for managing prompts with versioning, team collaboration, and API deployment. Its Playground runs prompts across OpenAI, Anthropic, and Google models simultaneously so users can compare outputs. Every save creates a version, with side-by-side diffs, token count comparisons, and one-click rollback. Team workspaces support Admin, Editor, and Viewer roles, plus activity logs and an audit trail. Applications can use the REST API to fetch an active prompt at runtime, including dynamic variables, so changes can take effect without redeployment. The Free plan includes unlimited prompts, API access, and import and export in JSON and Markdown, but limits Playground use to 50 runs per day and two model panels. Pro Team adds unlimited Playground runs, up to five panels, team workspaces, and priority support. It costs ₹599 a month under the Early Bird Offer; the page also shows ₹1,899. The site says data is encrypted at rest and workspace data is isolated with Row-Level Security.
