About Uppy and CodeRifts

In their own words, as submitted to SaaSHub.

Uppy
CodeRifts

No description of Uppy yet.

CodeRifts decides whether a change to an API or MCP contract may merge, and signs the decision. A GitHub App and a GitHub Action post two checks on every pull request that touches a contract file: CodeRifts / issuer and CodeRifts / contract-gate. Require both in branch protection, and a breaking...

  • Resumable Uploads
    Uppy supports resumable file uploads, allowing users to resume interrupted uploads rather than starting over from scratch.

    Uppy has an active community and extensive documentation, making it easier for developers to find help and integrate it into their projects.
  • Open Source
    Uppy is an open-source project, which means it can be freely used and modified, and benefits from contributions from developers around the world.

Possible disadvantages

  • File Size Limitations
    Depending on your backend and configuration, there may be limitations on the maximum file size that can be uploaded using Uppy.
  • Complexity for Advanced Use Cases
    For more advanced use cases, such as integrating custom storage backends or complex workflows, Uppy can become complex and might require significant configuration and customization.
  • Dependency Management
    Uppy has multiple plugins and dependencies, which can make managing updates and compatibility more challenging for developers.
  • Browser Compatibility
    While Uppy supports most modern browsers, some older or less common browsers may have compatibility issues or require polyfills.
  • Performance Overhead
    The modular nature and extensive feature set can introduce some performance overhead, particularly for large-scale or high-traffic applications.
  • Learning Curve
    Although Uppy is designed to be user-friendly, there can be a learning curve for developers new to the library, especially when dealing with its more advanced features.
  • Limited Built-in Security Features
    Uppy does not provide built-in security features like file scanning for malware or deep authentication mechanisms, requiring developers to implement additional security measures.
  • Signed decision receipts
    Every decision comes with a signed receipt you can verify offline, without asking CodeRifts.
  • Policy Engine
    Breaking budgets, freeze windows, approval matrix
  • Breaking Change Detection
    10+ change types, OpenAPI schemas
  • Offline Verification (OVSE)
    A public, MIT-licensed verifier checks any receipt with no API key, no account and no CodeRifts server in the loop.
  • MCP server with three tools
    preflight_change_set, verify_receipt and get_decision_details, listed in the official MCP Registry; works with Claude Code, Cursor and custom hosts.
  • Merge enforcement on GitHub
    A required, app-bound status check stays red until a grant exists; enforce_admins on, workflow pinned by SHA.
  • Published proof boundaries
    The 'does not prove' limits are served live at /.well-known/coderifts.json — what a decision does not establish is a field in the output, not a footnote.
  • Named-state verdicts
    CONTINUE, CONTINUE_WITH_MONITORING, REQUEST_APPROVAL or STOP — a state you can branch on, never a score or a boolean.
  • Single-use grants
    One grant, one execution; an adapter that cannot prove atomic consumption cannot report the atomic success state.
  • Guarded tool table for AI agents
    In the tool table handed to the agent, an ungranted mutation does not exist — nothing to call, not an error.
  • Multi-protocol contract diff
    Breaking-change detection for OpenAPI, GraphQL, gRPC, AsyncAPI and MCP tool schemas, with the same signed verdict on every path.

Questions & Answers

As answered by people managing Uppy and CodeRifts.

What's the story behind your product?

CodeRifts's answer:

A field rename broke a POS system across 19 restaurants for a week. The PR passed review, tests were green, nobody checked the contract. CodeRifts started as the check that catches this before merge. Then the author of the change stopped being a person: AI agents now propose and execute contract changes, and the question became not just "is this safe" but "was this authorized, and can you prove it later" — which is what the signed, offline-verifiable gate answers.

Which are the primary technologies used for building your product?

CodeRifts's answer:

Node.js and Express; Ed25519 signatures with a pinned public keyring; PostgreSQL on Railway; an MCP server with three tools listed in the official MCP Registry; the GitHub Apps and Checks API for merge enforcement; a JavaScript and Python receipt verifier (MIT); Cloudflare Pages for the site. Verified live with npx @coderifts/conformance.

What makes your product unique?

CodeRifts's answer:

Every decision CodeRifts makes is an Ed25519-signed receipt that anyone can verify offline — no API key, no account, no CodeRifts server in the loop. The verdict is a named state (CONTINUE, CONTINUE_WITH_MONITORING, REQUEST_APPROVAL, STOP), not a score, and it ships with its own published limits: the "does not prove" statements served live at /.well-known/coderifts.json. Where authorization cannot be established, the answer is never an assumed yes.

Why should a person choose your product over its competitors?

CodeRifts's answer:

Diff tools tell you what changed in a contract. CodeRifts decides whether an AI agent may proceed with that change, spends a single-use grant on execution, and keeps the GitHub required check red until the grant exists — and the evidence survives us: the receipt verifies against a pinned key snapshot with a public MIT verifier. If your question is "who allowed that, and can I prove it without trusting the vendor's database", that is the difference.

How would you describe the primary audience of your product?

CodeRifts's answer:

Three people. The one who runs AI agents in production and needs "who allowed that change" to be more than a log line they also control. The one adding a gate to an agent runtime who needs a state to branch on, not a score. And the one an auditor will ask, who needs evidence that survives the vendor. If none of these is you yet, you probably do not need this today.

Who are some of the biggest customers of your product?

CodeRifts's answer:

  • No paying customers yet. CodeRifts is in beta; the first external organization onboarding is the milestone we publish next — not before.
