Elva vs SKI: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Elva and SKI — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Elva
Theneo
Reads your repositories to discover every API, scores and governs them, then exposes them to developers and AI agents via hosted MCP servers.
Key features
- Spec-Free API Discovery: Elva scans repository code directly to find endpoints and generates OpenAPI 3.1 as output, so no existing spec is needed to start.
- Endpoint Scoring: Every collection is graded on design, developer experience, AI readiness, security and performance, with the weakest collection surfaced first.
- AI Fix Pass: A one-click agent writes missing descriptions from code, types response schemas and documents auth, then rescores the collection.
- API Contracts: Per-audience contracts pin the exact endpoints and fields a partner, internal team, public developer or MCP client receives, excluding PII and internal fields.
- Breaking Change Enforcement: Each commit is diffed against published contracts, showing the schema diff, affected consumers and tools, and blocking publish by policy.
- Hosted MCP Servers: Contracts generate MCP servers hosted behind Elva's gateway with OAuth2, scoped keys, per-tool authorization and exportable call logs.
- MCP Playground and Agent Feedback: Test the server with a live model, then read the complaints agents file about confusing or failing tools, scored back into the catalog.
- Multi-Target Publishing: One approved contract ships as OpenAPI spec, Theneo docs, MCP server, Postman collection and a typed TypeScript SDK in sync.
Best for
- API Inventory Audit: Discover undocumented or forgotten endpoints across a large codebase and get a ranked list of what to fix first.
- Agent Enablement: Expose an internal service to Claude, Cursor or ChatGPT as a governed MCP server instead of hand-writing tool wrappers.
- Partner Integration Safety: Publish a restricted contract to an external partner and have Elva block commits that would break their integration.
- PII Scoping: Keep customer emails and internal ops annotations out of a public or agent-facing surface while the same endpoints serve them internally.
- Zombie Endpoint Retirement: Prove no active consumer references an endpoint before deleting it, using contract and call-log evidence.
- Enterprise Security Review: Satisfy SOC 2, ISO 27001 and GDPR questions and wire agent access into an existing SSO and SCIM identity provider.
- Documentation Drift Control: Keep docs, SDKs and Postman collections regenerated from code on every merge instead of maintained by hand.
SKI
agentcall.dev
A macOS and Windows voice assistant for AI coding agents. Talk to Claude Code, Cursor, Codex, Gemini CLI, or OpenClaw and hear them answer, fully on-device.
Key features
- On-Device Speech-To-Text: Local speech recognition runs on your machine so audio never leaves it, and the loop works offline.
- Neural Voice On-Device: A natural neural voice synthesizes replies locally, so you hear your agent respond in-line without cloud calls.
- Full-Duplex Echo Cancellation: Barge-in support lets you interrupt the agent mid-sentence and be heard cleanly.
- Multi-Agent Connectors: One-click integration with Claude Code, Cursor, Codex, Gemini CLI, and OpenClaw via a small skill each agent already understands.
- Approve-Before-Send Review Mode: Every transcript lands in an editable bubble first so nothing reaches the agent until you confirm.
- Meeting Transcriber: Captures meetings alongside coding sessions with the same on-device speech engine.
- Multi-Project Sessions and Agent Liveness: Handle multiple projects and see when the connected agent is actively listening or working.
- Global Hotkeys and Notch/Pill UI: Launch or mute with global hotkeys; docks into the Mac notch or a floating Windows pill.
Best for
- Voice-Driven Pair Programming: Talk to Claude Code, Cursor, or Codex while your hands are away from the keyboard.
- Hands-Busy Debugging: Ask your agent to run tests and read the failure back out loud instead of switching windows.
- Accessibility for Developers: Enable voice input and audio output for developers who prefer or need non-keyboard workflows.
- Private On-Device Coding: Work with confidential codebases where nothing spoken can be sent to a cloud STT service.
- Meeting + Coding Overlap: Transcribe standups and design meetings on the same on-device engine you use to talk to your agent.
- Live Demos and Screencasts: Build features by voice in front of an audience with a natural back-and-forth loop.
