About

Manage source code context and generate optimized prompts. Ship with ChatGPT and Claude. 16x Prompt helps developers manage source code context and prompts to complete complex coding tasks on existing codebases. Enter your own API key to use APIs from OpenAI, Anthropic, Azure OpenAI, OpenRouter, or 3rd party services that offer OpenAI API compatibility, such as Ollama and OxyAPI. Using API avoids leaking your code to OpenAI or Anthropic training data. Compare the code output of different LLM models (for example, GPT-4o & Claude 3.5 Sonnet) side-by-side to see which one is the best for your use case. Craft and save your best prompts as task instructions or custom instructions to use across different tech stacks like Next.js, Python, and SQL. Fine-tune your prompt with various optimization settings to get the best results. Organize your source code context using workspaces to manage multiple repositories and projects in one place and switch between them easily.

About

StackRails is a software architecture and AI coding governance platform for engineering organizations. It builds a live knowledge graph of repositories, services, APIs, events, and cloud infrastructure, then provides coding agents with architecture and policy context through the Model Context Protocol (MCP). It supports Claude Code, GitHub Copilot, Cursor, and OpenAI Codex, and checks generated code against organization-defined rules on developers’ machines and in pull-request workflows. Teams can use it to map cross-repository dependencies, assess change impact, maintain architecture documentation, manage engineering policies, and run AI-assisted architectural reviews. StackRails is available as a hosted EU service, in customer-managed cloud environments on AWS, Microsoft Azure, or Google Cloud, and as an on-premises deployment.
