BearDrive vs Elva: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of BearDrive and Elva — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
B
BearDrive
Runbear
Open-source shared folder that syncs the files your team's AI agents create, with versions, authorship, and shareable links — no server required.
Key features
- Filesystem-native sharing: The shared surface is your local filesystem, so any AI agent that writes files can participate without a special SDK.
- Second-scale sync: Files sync to teammates within seconds of being written, so an agent's output is immediately available to another teammate's agent.
- Automatic versioning: Every synced change becomes a version that is kept, attributed to a user or agent, and restorable.
- Shareable web view: Every file gets a link you can drop into Slack; teammates open a web view of the file with no install required.
- Team history and authorship: See who — or which agent — produced each file and when, across the whole team.
- Open source, self-hostable: AGPL-3.0 with the server, teams, history, and links code publicly available on GitHub.
Best for
- Agent-produced research sharing: An analyst's research agent drops long-form HTML reports into a shared folder; a teammate's agent reads them the next minute.
- Design/data handoff: A design or data agent writes assets or CSVs at a stable path so downstream agents pick them up without brittle Slack uploads.
- Cross-agent workflows: One agent's output is another agent's input — BearDrive keeps the artifacts and their versions instead of scattering copies.
- Team memory for AI work: Teams keep a browsable history of everything their agents have produced, restorable and attributable.
- Self-hosted deployments: Regulated teams host BearDrive on their own infra to keep AI-produced files inside their perimeter.
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.
