Experiential Labs
Experiential Labs
Open-source AI gateway that routes every model through one endpoint at provider cost, then improves that traffic with caching, routing and fine-tuning.
Key features
- Unified Model Endpoint: One OpenAI-compatible POST endpoint fronts every hosted provider, your own bring-your-own keys and your own GPUs, so switching models is a parameter change rather than an integration.
- Zero-Markup Routed Tokens: Routed traffic bills at the provider's list price with 0% added on top, with the company earning on hosted inference and the Pro plan instead of on your tokens.
- Model Recommendation from Traffic: The intelligence layer watches real request patterns and tells you when switching models would win, including newly released models on the day they ship, with optional per-prompt optimization.
- Caching Opportunity Detection: Identifies where cache hit rate could improve and shows the projected savings, with repeated tokens returning at 90% off once enabled.
- Traffic-Trained Custom Models: Fine-tunes a model on your own traffic and proves it in closed-loop simulation before it ever serves, then exposes it through the same endpoint you already call.
- Spend Attribution Console: Breaks requests and dollars down by agent, person, model, provider and day across the whole organization, alongside catalog, usage and limits.
- Live Request Logs and Metrics: Streams per-request time-to-first-token, token counts, provider, status and cost, with dashboard rollups for requests, spend, p50 TTFT and cache hit rate.
- Governance Controls: Budgets, provider allowlists and attribution are available from the free tier upward for controlling who can spend what on which models.
Best for
- Consolidating Multi-Provider Access: Replace separate SDKs and keys for OpenAI, Anthropic, Google and others with a single endpoint and key across every application.
- Cutting Inference Spend: Use caching recommendations and model-switch suggestions to lower the cost of an existing production workload without changing application code.
- Replacing a Frontier Model with a Small One: Distill or fine-tune a small model on your own traffic for a narrow repetitive task and serve it at a fraction of frontier-model cost and latency.
- Chargeback and Budgeting: Attribute AI spend to individual agents, teams or people for internal cost allocation and to enforce per-key budget caps.
- Evaluating New Model Releases: Compare a newly shipped model against your current one on your own traffic before committing to a migration.
- Hybrid Local and Hosted Serving: Route some workloads to self-hosted GPUs at zero marginal cost while sending the rest to hosted providers through the same interface.
- Self-Hosting the Gateway: Run the open-source gateway inside your own infrastructure when hosted routing is not an option.

- Self-hosted deployment (run on customer infrastructure)
- One-time license/payment model (no recurring monthly subscription)
- Email marketing functionality (campaigns, lists, templates) - platform-level capability implied by product description
- Control over hosting and data due to on-premise deployment
Best for
- Small businesses that want to avoid monthly SaaS fees and prefer a one-time license to host email marketing on their own servers.
- Agencies and consultants that deploy white-label, self-hosted email marketing instances for multiple clients and control billing per client.
- Privacy-conscious organizations and regulated industries that must keep customer data on-premises rather than in third-party cloud systems.
- Developers and IT teams that want full control over deliverability settings (DKIM/SPF), SMTP integration, and monitoring for transactional emails.
- Teams migrating from subscription-based email platforms to a single upfront purchase to reduce long-term operating costs.
- Event-driven systems sending transactional emails where embedding a self-hosted mailer reduces dependency on external transactional services.
- Organizations wanting to host email marketing tooling on-premises or in their own cloud
- Teams seeking to avoid recurring subscription costs via a one-time purchase
- Businesses that require direct control over email infrastructure and data for privacy or compliance
- Integrating platform with existing SMTP relays or internal systems (self-hosted integration scenarios)
