Elva vs MashuPack: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Elva and MashuPack — 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.
MashuPack
MashuPack
Browser-based tool that converts local code repositories into one clean, structured text file optimized for ChatGPT and Claude.
Key features
- Selective Subsystem Export: Choose exact files, directories, or logical subsystems from a repository and export only the relevant code and metadata to reduce noise fed to models.
- Single Structured Text Output: Compiles selected code into one coherent, structured text file tailored for ChatGPT and Claude to avoid context fragmentation and simplify prompts.
- Client-side Processing (No Backend): Runs entirely in the browser with no repository uploads or backend servers, keeping source code local and minimizing exposure of sensitive data.
- Intelligent File Merging: Merges files while preserving structure and dependency relationships (imports, module boundaries, README/context) so the resulting text maintains meaningful context for LLMs.
- No Account Required: Immediate use without sign-up or authentication—streamlines quick exports and trialing on local projects.
- Model-Targeted Formatting: Produces outputs formatted and structured specifically to improve ingestion by conversational models (e.g., clear file separators, dependency notes, and minimal noise).
- Client-side processing: runs entirely in the browser, keeping code local and avoiding uploads to servers
- Selective export: pick exact files or subsystems from a repository to include in the output
- Single structured output: compiles selected files into one structured text file optimized for LLM input
- Intelligent file merging: merges files while preserving structure and dependencies to reduce context fragmentation
- No account or backend required: use without sign-up or remote storage
- Privacy-first workflow: code remains in the browser; no repository upload
- Model-targeted formatting: output intended for direct use with ChatGPT and Claude
Best for
- LLM-Powered Code Review: Extract a module plus its dependencies into a compact text file to feed to ChatGPT/Claude for targeted code review, bug-finding, or improvement suggestions without exposing the whole repo.
- Refactoring & Design Explanation: Collect a subsystem and supporting files to prompt an LLM to explain architecture, suggest refactors, or generate design docs from the precise context.
- PR/Change Summaries: Produce a condensed, structured snapshot of changed files and context to generate high-quality PR descriptions or release notes via an LLM.
- Onboarding Snippets: Create focused, readable extracts of key files and documentation to accelerate onboarding by asking an LLM to summarize a subsystem for new team members.
- Secure Local Analysis: Prepare local code extracts for offline or privacy-conscious LLM workflows because processing happens in-browser with no uploads.
- Bug Reproduction & Debugging Prompts: Package the minimal set of files and configuration needed to reproduce an issue, then feed that to a model to generate debugging steps or hypotheses.
- Preparing a codebase excerpt for debugging or review with ChatGPT or Claude
- Creating a single, structured context file to feed large repositories into a chat model
- Sharing specific subsystems or file sets with teammates or consultants without uploading entire repo
- Reducing context window fragmentation when using LLMs on large projects
- Quickly compiling repository context for ad-hoc prompts, code summarization, or architecture queries
