The facts, with their sources

What it does

Writes code: PartlyIt authors complete tests from a plain-language sentence, but the vendor positions coding agents as the writers of application code and Studio as the independent check on it.Agents write the code. ‍Studio proves it works.functionize.com
Debugs and fixes: PartlyStudio diagnoses a failing run, names the cause and lands the fix in the test itself; the repair is to the test step, not to the application source that broke it.Studio investigates the run and names the failing step and the cause. Then it applies the fix and validates it with a run.functionize.com/agent-tasks
Writes tests: YesGenerating end-to-end tests from a described flow is the core job: steps, element identification and verifications come back generated and already run.The full test comes back: steps, element identification, and verifications, generated from your sentence and run immediately.functionize.com/agent-tasks
Ships it: NoIt stops at proving the change: suites, reports and fixes come back, while the release decision is explicitly left with the buyer rather than automated.You still own what good means, which risks matter, and the call to shipfunctionize.com/agent-tasks
Done-for-you service: NoThis is software the buyer runs themselves: sign-up is self-serve, there is nothing to stand up, and no engagement where Functionize staff build or operate suites for you.Log in and start testing. No infrastructure, nothing to maintain.functionize.com/architecture

How much it does unattended

Runs autonomously: YesA single prompt produces a built, executed and self-maintained test, including re-runs on failure and fixes applied without a person in the step.Describe any flow in plain language. Studio builds the test, runs it across browsers, and fixes it when the app changes.functionize.com/agent-tasks
Multi-agent: YesThe architecture splits the work between a planning agent and an execution agent, with the plan written so a second agent can act on each ordered step.An agent reads what you asked for and maps it into ordered test steps, each one specific enough for another agent to act on.functionize.com/architecture
Agent permissions: YesYou set how far the agent may go and every edited step writes a restore point you can inspect or roll back with one click, so changes are reversible.Any edited step writes a restore point that records what changed, on which step, and why, and you roll back to the exact state before it with one…functionize.com/architecture

Which models it runs on

Claude: NoThe reasoning and element models are Functionize's own rather than a hosted frontier model; Claude appears only as an MCP client that calls Studio, not as a model option.The models, the data layer, and the execution engine are ours. Built for testing, sharpened on your app.functionize.com
GPT: NoThe vendor answers the wrapper question directly: the element model and data layer are in-house and no third-party model endpoint sits under a result.No. The element model and the data layer are built in-house and trained on 200M+ UI datapoints from real runs.functionize.com/architecture
Gemini: NoNo external model provider is selectable; the vendor states there is no moving third-party endpoint beneath a verdict, which rules Gemini out alongside the rest.there's no moving third-party endpoint underneath the resultfunctionize.com/architecture
Model choice: PartlyThe vendor picks the models by default, and only the enterprise deployment bullet offers bringing your own model and data alongside private deployment.✓ Your model, your datafunctionize.com/architecture

Where you use it

In your editor: YesThe MCP server puts test creation and diagnosis inside the editor-side agents developers already run, with config snippets for Cursor, Windsurf, Gemini and Codex.Build, run and diagnose tests against your real app from Claude Code, Cursor or Copilotfunctionize.com/mcp
In your pipeline: PartlyEnterprise prose claims CI/CD hookup through the same integration layer, yet the integrations page itself is a 'Coming Soon' placeholder with an MCP waitlist, so pipeline use is not demonstrably live.And it plugs into the tools your teams already use: your coding agents through MCP, CI/CD, Jira, Slack, and your identity provider.functionize.com/enterprise
In a browser: YesStudio is a hosted web application: you log in, prompt it in chat, and read runs, reports and credit usage in its sidebar.You can see your usage in the Studio sidebar and in Reports.functionize.com/pricing

Whose machine it runs on

Self-hosted: PartlyExecution normally runs in the Functionize cloud, with deployment inside your own environment offered as part of the enterprise posture rather than on self-serve plans.Deploy in the Functionize cloud or inside your own environmentfunctionize.com/architecture
Open-source runtime: NoThere is no way to run it without Functionize: both the web product and the MCP server require signing in with a Functionize account before any agent work happens.Sign in with your Functionize account in the browser. No API key.functionize.com/mcp
Runs in your cloud: PartlyFor internal or VPN-bound environments the execution layer runs inside your network over encrypted tunnels, but the default is the vendor's isolated cloud.When you need to reach internal or VPN bound environments, it runs inside your network through secure encrypted tunnels that keep everything inside…functionize.com/architecture

Building with it

Tracing and evals: YesEvery run is recorded with pass/fail, browser and duration, each step screenshotted, each element match shown with its bounding box, and reports export to CSV.Every run recorded: pass or fail, browser, duration. Filterable reports, exportable to CSV.functionize.com/agent-tasks

What it costs to run

How it meters: YesBilling meters agent work in credits from one shared balance; human work such as editing, reading reports or changing settings consumes nothing.A credit is the unit that measures agent work. Studio subtracts every agent task from the same credit balance.functionize.com/pricing
Price per 1,000 requests: Yes$0.005 per 1,000 requests in Scale, its $100 plan fee over 20,000,000 requests, its cheapest mode.$100/mofunctionize.com/pricing
Free credit: Yes800,000 free credits, a month.800,000 credits/mofunctionize.com/pricing
Free tier: YesA standing $0 plan with no time limit and no card gives all agent capabilities, five parallel runs and a monthly credit grant.The Free plan includes all agent capabilities, 400,000 credits each month, and five parallel runs. You do not need a credit card.functionize.com/pricing
MCP server: YesA hosted MCP server at mcp.functionize.com lets any MCP client build, run and diagnose tests in chat, with OAuth sign-in instead of an API key.The Functionize MCP server connects your coding agent to Functionize Studio. Ask for a test in plain language and the result comes back in the chat.functionize.com/mcp
Bring your own key: PartlyInference is normally the vendor's own; bringing your own model and keeping your own data is presented only as part of the enterprise deployment option.functionize.com/architecture

Buying it for a team

A company can buy it: YesEnterprise buys on invoice or PO with a twelve-month minimum, multi-team management and premium support, alongside self-serve card plans for smaller teams.Invoice/PO billing, 12-month minimumfunctionize.com/pricing
Seat model: PartlyPlans are priced per plan and credit allowance rather than per seat, but seats are still charged and prorated at a rate set in your order form or online agreement.New seats are charged at the agreed upon rate in your Order Form or online purchase agreement.functionize.com/usage-limits
Pooled budget: YesGrowth, Scale and Enterprise draw agent work from one team-wide credit balance; only individual allocations are described as unpooled.The Growth plan and the Scale plan use one credit balance for the whole team.functionize.com/pricing
Admin controls: PartlyRole-based access control arrives with the cheapest paid plan and is absent from Free, while multi-team management is held back for Enterprise.SSO and Role-Based Access Controlfunctionize.com/pricing
Audit log: PartlyA full audit trail is listed among the enterprise deployment controls; nothing on the self-serve plan rows offers administrative logging.functionize.com/architecture
Single sign-on: PartlySSO ships from the $20 Growth plan upward, and the plan comparison marks it absent on Free, so the free tier cannot be put behind an identity provider.functionize.com/pricing

What happens to your code

Opt out of training: PartlyRaw customer content is not used to train models for other customers without written consent, but de-identified aggregated usage metadata is used for model refinement with no stated opt-out.We expressly do not use raw Customer Content or proprietary application data to train models for the benefit of other customers without your explicit…functionize.com/privacy-policy
Getting out: PartlyExporting results is free and never costs credits, but unused credits expire at each reset and are forfeited on cancellation with no refund or proration.No. If you cancel, the subscription stops and you lose the credits that remain.functionize.com/pricing
Certifications: YesSOC 2 Type II is claimed with the report available to a security team on request, and GDPR and CCPA data rights are set out in the privacy policy.Furthermore, we maintain a rigorous audit schedule and adhere to SOC 2 Type II compliance standards to verify the ongoing effectiveness of our…functionize.com/privacy-policy
