We build
in public.
The platform sits on top of an open-source Go ecosystem — langrails, memoryrails, mediarails, guardrails — that you can use on its own, without a PromptRails account. Plus client SDKs, an n8n integration, and the surrounding tooling.
langrails
Unified Go interface for 24 LLM providers — chains, tools, streaming, retries, prompts, MCP. Use it standalone or as the engine inside PromptRails.
SDKs & clients.
Native client libraries and editor / desktop integrations for talking to the PromptRails platform from your code.
Official Python SDK with async, streaming, and structured-output helpers.
TypeScript-first SDK for Node, edge, and browser runtimes.
Idiomatic Go client with context-aware streaming and typed responses.
Single-binary CLI for managing agents, prompts, deployments, and credentials from the terminal.
Author and run agents from inside VSCode — install, log in, ship.
Desktop monitor for inspecting local agent sessions, traces, and tool calls.
Embeddable chat surface for talking to your deployed agents.
Composable Go libraries.
Standalone Go packages that the PromptRails platform is built on. Use any of them on their own — no PromptRails account required.
Pluggable agent memory — short-term, sliding-window summaries, vector recall, and persistence backends.
Unified API for image, audio, and video generation across ElevenLabs, Fal, Runway, and other media providers.
14 built-in scanners — PII, toxicity, prompt injection, jailbreak — composable into block / redact / log policies.
Smaller, focused utilities for the Go AI stack — prompts, retries, tracing primitives, common types.
Ecosystem.
Workflow integrations, install / distribution helpers, dashboards, and learning material around the platform.
PromptRails nodes for n8n — trigger agents from any n8n workflow.
Tap formulas for `brew install promptrails/tap/cli` and friends.
Drop-in Grafana dashboards for PromptRails platform telemetry.
AI coding-assistant skills (Claude Code, Cursor, Windsurf) that teach the assistant how to work with PromptRails.
End-to-end example agents and pipelines across Python, JavaScript, and Go.
Local emulator for running PromptRails-shaped flows on your laptop.
