Ops platform for AI engineering teams that combines LLM observability, prompt management, evaluations, test runs and human review for AI products and agents.

Freeplay is an ops platform for teams building AI products and agents. It records every model call as a completion tied to its prompt template version, groups calls into traces for agent flows and sessions for whole interactions, and lets product managers, engineers and domain experts search, filter and review the same production data. Prompt templates are versioned and deployed across environments, and can be bundled into a release so production prompts stay reviewable in Git.

Evaluations run as model-graded judges, code checks and human labels, with a workflow for aligning judges to human judgment. Test runs score prompts in isolation or a whole agent end to end against datasets, from the app, the SDK or the API, and online evaluations score sampled production traffic. Automations watch production logs and act on matches by running evaluations, routing items to review queues, growing datasets or posting to Slack, and AI insights summarize patterns in evaluation and review data.

Freeplay stays out of the runtime call path: customers call their own models with their own keys, across providers such as OpenAI, Anthropic, Azure OpenAI, Amazon Bedrock and Groq, and admins control which models the team may use. It ships a REST API with an OpenAPI specification, open source Python and Node SDKs plus a Java and Kotlin SDK, and an experimental MCP server. Freeplay states it holds SOC 2 Type II, and offers SAML SSO, SCIM and Bring-Your-Own-Cloud deployment in AWS, GCP or Azure on its Enterprise tier. Accounts start with a free sign-up.

Integrations

Multi vendor model support across OpenAI, Anthropic, Google Vertex, AWS Bedrock, and Groq, with SDKs for Python, Node and TypeScript, and the JVM that keep Freeplay out of the runtime hot path. Partnerships such as MongoDB Atlas support RAG workflows, and prompts can be fetched at runtime or build time.

In practice

Your PMs track LLM test cases in a spreadsheet and copy paste into a playground while engineers coordinate prompt changes with deploys. Freeplay gives everyone one place to edit prompts, run batch tests, and ship from the browser.

You shipped an AI feature and have no idea what's happening in production. Freeplay logs every call, runs evals on live traffic, and routes flagged results to review queues so problems surface before customers complain.

Your LLM as judge scores do not match what your domain experts consider good. Freeplay's alignment workflow calibrates the automated judges against human labels so the eval scores you ship against reflect your team's standards.

Integrations & Tool Calling Partial

Tool schemas are versioned inside prompt templates, and Freeplay records the tool calls a customer's agent makes, integrates with LangGraph, the Vercel AI SDK, Google ADK and OpenTelemetry to capture traces, and posts automation alerts to Slack. The customer's own code executes every tool call; no connector that lets an agent read or write a real system through Freeplay is documented.

Workflow Orchestration Not documented

Whatever way the customer manages orchestration, Freeplay observes, evaluates and tests agents built elsewhere and records multi-prompt chains as traces. No sequencing, branching, retries or routing of agent steps run by Freeplay is documented.

Knowledge Grounding & RAG Not documented

Retrieved context that a customer's application passes to a prompt is logged, and RAG pipelines can be tested end to end. No document ingestion, index, retrieval layer or knowledge API that grounds an agent in company data is documented.

Human Oversight & Guardrails Partial

Review queues assign production completions and traces to named reviewers for human evaluation, and automations route guardrailed or low-scoring responses into those queues so a person reviews them. Review happens after an output is produced; no approval step, checkpoint or pause that holds an agent's action for a person is documented.

Security, Identity & Governance Full

SOC 2 Type II certification is stated as achieved, with details on Freeplay's trust center, and HIPAA Business Associate Agreements are offered; customers get SAML single sign-on through WorkOS with Okta, Microsoft Entra ID, Cisco Duo, OneLogin and JumpCloud, SCIM provisioning and deprovisioning, four account roles with project-level role overrides, mandatory multi-factor authentication, revocable API keys, and a configurable retention window on Enterprise.

Observability & Auditability Full

Every LLM call is recorded as a completion tied to its prompt template version, and Freeplay groups completions into traces for agent flows and into sessions for whole interactions, records tool calls, and lets teams search and filter production logs by inputs, outputs, evaluation scores, metadata, cost and latency; it ingests OpenTelemetry traces, exports traces to CSV and exposes search endpoints for sessions, traces and completions. Logged data is kept 90 days by default and the window is configurable on Enterprise plans.

Triggers & Channel Coverage Full

Automations run in the background, monitor production traffic continuously and act when logs match a saved search: they run evaluations, route completions to a review queue, add them to a dataset or post a Slack notification. Evaluation Insights runs a weekly AI analysis of production evaluation data. So work starts on an incoming log or on a schedule without a person asking.

Pricing

Free sign-up · paid and Enterprise plans not readable

Not readable: the pricing page returns a site-not-found page; the docs name an Enterprise tier but no meter or price

Free tier

Included quota

Free tier to get started. Paid tier limits and quotas are not publicly listed.

What is public

Freeplay does not publish a price card. It offers a free tier to sign up and start, and directs teams to contact the company for paid plans, self hosting, and enterprise terms.

Billing mechanics

Not publicly disclosed. Evaluation and observability platforms of this type typically bill on a combination of seats and logged volume such as traces or completions, but Freeplay does not list specifics.

Cost watchouts

SAML SSO, SCIM, Bring-Your-Own-Cloud and retention beyond the default 90 days require an Enterprise contract, and Freeplay's AI features consume model tokens that count against the customer's own provider keys where those are used.

Variable cost rationale

No meter is readable. The docs note that AI features use model tokens tracked separately in the usage dashboard, which bill to the customer's own provider keys where configured.

Additional watchouts

Because pricing is not listed, teams must scope cost directly with the vendor, and the eventual bill likely depends on user seats and the volume of logged completions or traces.

Overage / add-ons

Not publicly disclosed.

Sales call required

Mixed (some tiers require a call)

Free / trial

Free account sign-up, per Freeplay's docs

Lowest paid plan

Not readable; the pricing page returns a site-not-found page

Commercial notes

Free account sign-up through the app, with self-hosting and enterprise options arranged with the company; the Enterprise tier carries SSO and SCIM, Bring-Your-Own-Cloud and configurable retention.

Key ambiguities

The marketing site and its pricing page return a site-not-found page, so free tier limits and paid plan prices could not be read; the product, docs, sign-up and status page are live.

Cancellation / refund

Not publicly disclosed; arranged with the vendor.

Support SLA / resale

Not publicly disclosed; enterprise support and SLA terms are arranged with the vendor.

Missing data

All paid pricing, tier limits, seat costs, and enterprise terms are not public and require contacting Freeplay.
