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

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

Backgrind

Freemium

Always-on-top desktop overlay for macOS and Windows that runs your AI coding agent and pings you only when it needs approval or input.

Always-On-Top Overlay: Floats your coding agent over any app, editor, browser or fullscreen game so it stays in view.
Bring Your Own Agent: Works as a thin frontend over Claude Code, Cursor or a Backgrind-hosted model using your existing login and history.
Attention-Only Alerts: Stays quiet while the agent works and flashes or chimes only when it needs approval or input.
Inline Approvals: Surfaces command-run and dependency-install requests so you can approve or reject them in place.
Customizable Window: Drag, stretch, recolor and fade the floating window to fit your workspace.
Cross-Platform: Available for both macOS and Windows.

Background Coding: Kick off a refactor or build and keep working elsewhere until the agent needs you.
Supervising Multiple Agents: Keep several agent sessions visible in floating windows at once.
Vibe Coding: Let casual builders run an agent without learning a full IDE workflow.
Long-Running Tasks: Monitor test runs and multi-step builds without staring at a terminal.
Approval Gating: Review and authorize potentially risky commands before they execute.

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.
