Prompt Management
Create, organize, version, and deploy prompts from a central workspace instead of burying critical AI behavior inside application code.
Built for teams shipping AI into production
The AI Control Plane for Software Teams
Fusion Plane gives engineering and product teams one centralized layer to manage prompts, route model requests, monitor usage, control costs, and govern AI behavior across every application.

The problem
AI is moving fast. Your infrastructure is getting fragmented.
As teams add AI features across products, workflows, and internal tools, critical AI logic starts spreading everywhere: hardcoded prompts, direct provider calls, duplicated routing rules, inconsistent logging, and limited visibility into cost or performance.
What starts as a few experiments quickly becomes difficult to manage, monitor, and govern.
Core capabilities
Everything your team needs to operate AI in production.
Fusion Plane brings the operational pieces of AI development into one place, so teams can move faster without scattering critical logic across every application.
AI Gateway
Route AI requests through a single, consistent layer that gives your team visibility and control across applications, environments, and providers.
Model Routing
Route requests across models and providers based on use case, cost, latency, quality, availability, or fallback rules.
Usage & Cost Intelligence
Track token usage, model spend, and request volume by application, feature, customer, environment, or team.
AI Observability
Monitor requests, responses, errors, latency, and model behavior so teams can debug AI-powered features with confidence.
Evaluations & Governance
Compare prompts, models, and configuration changes before they affect real users, while centralizing policies, approvals, access controls, and auditability.
Built for
Designed for the teams responsible for making AI work at scale.
Fusion Plane helps technical and product teams move AI from scattered experiments to reliable production systems without losing visibility, control, or flexibility.
Engineering teams
Centralize AI integrations, model routing, observability, and deployment workflows so developers are not rebuilding the same infrastructure across every application.
Product teams
Experiment with prompts, models, and AI behavior more quickly while keeping changes visible, testable, and controlled.
AI-native SaaS companies
Manage AI behavior across products, customers, tenants, environments, and use cases from a single operational layer.
Enterprises adopting AI
Bring consistency, visibility, and governance to AI usage as teams move from isolated experiments to production systems.
How it works
A simple control layer for your AI stack.
Fusion Plane fits between your applications and the AI providers you already use, giving your team a central place to manage, monitor, and improve AI behavior.
01
Route requests through Fusion Plane
Applications call Fusion Plane instead of calling AI providers directly. Your team gets a consistent gateway for AI traffic across products and environments.
02
Manage prompts and routing centrally
Version prompts, configure model rules, define fallback behavior, and control how requests are handled from one platform.
03
Monitor, evaluate, and improve
Track usage, analyze performance, test changes, compare models, and optimize for quality, reliability, and cost over time.
Closed beta
Help shape the AI control plane for modern software teams.
We're inviting a small number of software teams building AI-powered products, workflows, and internal tools to help shape Fusion Plane.
If your team is already managing prompts, model calls, AI costs, or governance across multiple applications, request access and tell us what you're building.
