Elva vs Termexo: Features, Pricing & Which Is Better (2026)

A side-by-side comparison of Elva and Termexo — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.

Elva

Theneo

Freemium

Reads your repositories to discover every API, scores and governs them, then exposes them to developers and AI agents via hosted MCP servers.

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.

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.

Free

A local Windows workbench that runs Claude Code, Codex CLI, and other coding agents side by side in one grid.

Multi-Agent Grid: Open unlimited Claude Code, Codex CLI, and shell terminals in a customizable 1x1 to 6x6 grid that remembers each project's layout.
Waiting-For-You Alerts: Flashes the taskbar, fires system notifications, and keeps an on-screen banner when any agent is blocked on an approval or input prompt.
Session Resume Across Projects: Indexes the transcripts Claude Code and Codex already save on disk so you can search by name, path, branch, or model and reopen via the CLI's real resume command.
Model Routing Profiles: Keeps the Claude Code CLI but points it at Anthropic, DeepSeek, MiniMax, GLM, or any OpenAI-compatible endpoint, saved as one-click profiles.
Local-Only Credentials: API keys are written to Windows Credential Manager rather than plain-text config files, and nothing about your projects leaves the machine.
Native PTY Terminal: Real pseudo-terminal under each tab so interactive TUIs, colors, and shell prompts behave the same as they do in Windows Terminal.
Multi-Account Support: Run several accounts of the same provider in different tabs without re-login or config editing.

Parallel Agent Development: A solo developer runs Claude Code on the backend, Codex CLI on the frontend, and a shell on infra in the same grid so no agent sits idle waiting for attention.
Model Comparison: Point the same Claude Code CLI at Sonnet, DeepSeek, and MiniMax in three tabs to compare cost and quality on the same task without reinstalling anything.
Multi-Project Workflow: Keep several repositories open at once, each with its own grid layout and its own resumeable sessions, and switch projects without losing terminal state.
Never-Miss Approval Loops: Long-running agentic runs that pause for `y/N` prompts get surfaced via taskbar flash and notification so overnight or batch jobs don't stall unattended.
Local, No-Cloud Setup: Teams that require API keys to stay on the workstation get a workbench where nothing signs into a service and credentials live in the OS keystore.
