We build the rails
so you ship the agents.
PromptRails turns AI agents into production-grade systems. We believe building reliable AI shouldn't require cobbling together six SaaS tools.
Our mission.
AI agents are moving from experiments to production, but the tooling hasn't caught up. Teams struggle with prompt versioning, agent debugging, cost tracking, and safety guardrails. PromptRails brings the same rigor to AI development that modern engineering teams expect for traditional software — version control, observability, testing, and access control.
What we build.
Agent orchestration
Build simple agents or complex multi-agent pipelines with type-safe configurations and workflow builders.
Prompt management
Version, test, and deploy prompts with Jinja2 templates, input/output schemas, and model assignments.
Observability
Full execution tracing with span hierarchy, token usage, cost tracking, and error analysis for every agent run.
Safety & security
14 built-in guardrail scanners, API key scopes, IP restrictions, and human-in-the-loop approvals.
Developer tools
Python, JavaScript, and Go SDKs, a CLI, MCP server integration, and A2A protocol support.
Governance
RBAC, audit logs, and per-agent policy controls so platform teams can ship AI without losing oversight.
