Open-source versioning, tracing, and annotation tooling.

🚀 Production-ready template for building AI applications with Pydantic AI, FastAPI, PostgreSQL, Redis, LiteLLM, and comprehensive monitoring. Includes admin panel, CI/CD, testing, and observability out of the box.

PromptLane is an open-source platform for managing and versioning AI prompts. Built with FastAPI, it provides a robust API for prompt management, project organization, and seamless integration with your AI applications.

Using jinja to build prompts for LLMs and sqlite for prompt versioning

A comprehensive developer-first prompt management tool with git-like version control

Open-source, self-hostable AI cost & workflow observability. Find the prompt, customer, model, and workflow path behind every LLM cost spike — without a proxy.

Prompt-and-Tag is a tool designed to enhance AI-assisted development by seamlessly integrating your codebase with Large Language Models (LLMs). It creates synchronized snapshots of your code, making it easier to maintain context in AI conversations.

curl for prompts. Run .prompt files against any LLM (Anthropic, OpenAI, Ollama) from the terminal. Treat prompts as code — version them, review them in PRs, and test them in CI.

Open-source platform for managing, versioning, and AI-enhancing LLM prompts across teams

A prompt management & model selection platform for LLM engineering. Compare multiple models side-by-side, debug prompts, and find the best model for your use case.

LLM prompt evaluation studio with immutable prompt versions, slice-based regression checks, and real cost tracking.

Diff two LLM prompts at text, semantic, and behavioural levels. Detects changes to persona, constraints, output format, and safety guardrails. CI-ready exit codes. Zero mandatory dependencies.

Automated prompt optimization using mentor-agent architecture. Generate and refine prompts from labeled data.

Build a production-style AI system that ingests logs and metrics, detects anomalies, and uses an LLM to summarize incidents and suggest likely root causes, with observability and reliability in mind.

Open-source AI prompt management and engineering platform — version, organize, share, and iterate on your prompts.

AI Agent Testing Platform

Open-source LLMOps framework for prompt versioning, evaluation and regression testing in CI/CD pipelines.

Quote-to-Cash LLMOps Control Plane — token cost attribution, quality scoring, latency SLOs, prompt versioning, and semantic drift detection for production LLM revenue workflows. Local-first with Ollama. No API key required.

The ultimate collaboration platform for Prompt Engineers. Share, rate, version, and discuss system prompts. Powered by Next.js 14, TypeScript, and SQLite with automated context-aware translations.
