One source of truth for your APIs. Not five copies that drift.
You hold a growing set of services to a standard: OpenAPI for the REST surfaces, AsyncAPI for the events, Arazzo for the flows that cross them. Design sits in one tool, testing in another, linting in a CI step, and multi-service workflows in scripts nobody owns. None of those tools share a data model, so every contract change is re-entered by hand, and drift stays invisible until something breaks.
One model under all of it.
Put every API on one model and the work stops breaking at the seams. A change in one place is already the input to the next step, so design, governance, workflows, and generation move as one continuous piece of work. Film editors stopped roundtripping between separate tools the day the whole cut lived on one timeline. This is that, for APIs.
- 01
Three specs, first-class, in one place
OpenAPI, AsyncAPI, and Arazzo land in the same model, checked by the same pluggable rule engine, in the same app. The model records where every piece came from, so the same User schema described five different ways across five services stops hiding.
The model records where every entity came from and merges conflicting definitions into one agreed set of schemas, with you resolving any clash rather than the app collapsing them silently.
- 02
Workflows as artifacts, not glue code
A flow that crosses several services should be a versioned, reviewable artifact, not a script taped between tools. Spirefy Studio designs workflows against the model, with conditions, loops, and steps that run your own WebAssembly logic.
Workflows execute deterministically, with structured run logs and headless export for CI, so the same flow you design runs unattended in a pipeline.
- 03
AI that works on the model, not on text
Spirefy Studio ships a tuned, on-device model that works on the unified model directly. It runs on your machine, so your APIs never leave it, and it proposes changes as typed commands you review before they apply.
The tuned on-device model proposes changes as typed, reviewable commands you apply or discard, so the AI edits the model the same safe way a person does.
Built for the team that owns the estate.
Platform and API teams with many services, several spec formats, standards to enforce, and more than one person who needs the same picture of it all. If your API landscape lives across spreadsheets, CI configs, and tribal knowledge while every tool holds only a fragment, that gap is exactly what Spirefy Studio is built to close.

They are good tools, and if they fit your work you should keep using them. If you would rather have your collections next to your specs, importers for all three are marketplace plugins, and the app is native, works offline, and needs no account to start. Already deep in Arazzo? The model is a superset of the spec, from the team whose founder co-authored it. Run Spirefy Studio beside your current tool and let it earn the switch.

- OpenAPI, AsyncAPI, and Arazzo import into one model, with provenance
- A catalog of popular APIs you import operation by operation, alongside your own specs
- Conflict-aware merge into one agreed set of schemas, with you resolving clashes
- Spectral linting on a pluggable rule engine, plus AI-readiness scoring
- Workflow design and deterministic execution, with conditions, loops, WebAssembly logic steps, and run logs
- Headless export for CI pipelines from the spirefy CLI
- Server, documentation, and client SDK generation from the model
- Real-time collaboration, ad-hoc on your network or a persistent shared workspace on a service that cannot read your changes
- A tuned, on-device AI model that authors typed, reviewable commands, with nothing leaving your machine
- Signed, sandboxed plugins, a plugin-authoring CLI, and the public marketplace
On the roadmap
- Embedding the engine in Rust, Go, or C hosts through a stable C ABI
- More plugin languages and more export formats as the toolchain grows
- The on-prem licensed CI/CD runner you stand up on your own infrastructure
- RISC-V, validated end to end
