About Pactflow and Graphwake

In their own words, as submitted to SaaSHub.

Pactflow
Graphwake

No description of Pactflow yet.

Graphwake shows who consumes each endpoint of your OpenAPI specs and tells only those teams when a change is about to break them. When one team changes its API, the teams that call it often don't hear about it until something breaks in production. Diff tools tell you what changed, and...

Features and specs

What each product offers, as listed by its team.

Pactflow 5 features
Graphwake 9 features
  • Automated Contract Testing
    Pactflow allows teams to automate contract testing, ensuring that APIs between services are compatible and work as expected, which can reduce integration issues.
  • Consumer-Driven Contracts
    It supports consumer-driven contract testing, allowing consumers to define the contract which providers must adhere to, ensuring that changes in services don't break consumer expectations.
  • Seamless Integration
    Pactflow integrates well with CI/CD pipelines, enabling continuous testing and immediate feedback, which helps maintain high quality and smooth deployments.
  • Enhanced Collaboration
    By centralizing contract testing, Pactflow improves collaboration between teams, fostering better communication and understanding of service dependencies and contracts.
  • Version Control
    The tool offers version control for contracts, allowing teams to manage changes over time and test different versions against each other.

Possible disadvantages

  • Learning Curve
    Teams may face a learning curve when first adopting Pactflow, especially if they are not already familiar with contract testing methodologies.
  • Initial Setup Complexity
    Setting up Pactflow can be complex and time-consuming, as it requires configuring various parts of the service architecture to work with the platform.
  • Pricing Considerations
    For organizations with budget constraints, the cost associated with using Pactflow might be seen as a downside, especially for smaller teams or projects.
  • Limited Offline Support
    Due to its cloud-based nature, working with Pactflow might present challenges in environments with restricted internet access or stringent security policies.
  • Dependencies on Other Tools
    The effectiveness of Pactflow can be limited if not used in conjunction with other tools and processes that support robust microservices or API development.
  • Breaking change alerts
    Detects breaking changes in your OpenAPI specs and alerts only the teams that call the changed endpoints.
  • Alert channels
    Slack, Microsoft Teams and email. Each team picks its own channel.
  • Impact score
    Every pull request gets an explainable 0–100 score, plus the list of affected teams and what breaks for each one.
  • Service graph
    A map of who owns and who consumes every endpoint. Orphan endpoints are flagged.
  • Endpoint subscriptions
    Consumer teams subscribe to the endpoints they call. Producers don't maintain a consumer list.
  • CI/CD integration
    One step in GitHub Actions, GitLab CI, Azure DevOps or Jenkins checks every pull request.
  • Spec URL monitoring
    Watches a published OpenAPI spec URL and checks it every 30 minutes.
  • Change history
    Append-only record of API changes, subscriptions and ownership changes for incident reviews.
  • Security
    Reads your OpenAPI spec, not your code. Nothing runs in production. SSO with Entra ID on Pro.

Questions & Answers

As answered by people managing Pactflow and Graphwake.

Which are the primary technologies used for building your product?

Graphwake's answer:

  • Backend: .NET 10 API and workers
  • Database: PostgreSQL with row-level security per tenant
  • Frontend: Next.js and React
  • Breaking change detection: oasdiff
  • CI agent: Go, for GitHub Actions, GitLab CI, Azure DevOps, Bitbucket Pipelines and Jenkins
  • Hosting: Docker

What makes your product unique?

Graphwake's answer:

Most API tools stop at the diff: they tell you what changed. Graphwake also knows who calls each endpoint.

  • Team-level dependency map: who owns and who consumes every endpoint
  • Routed alerts: only the consumer teams that call a changed endpoint are alerted, in Slack, Microsoft Teams or email. Every other team stays quiet.
  • Impact score: every pull request gets an explainable 0–100 score and the list of teams it affects
  • Append-only history of changes, subscriptions and ownership, for incident reviews

Why should a person choose your product over its competitors?

Graphwake's answer:

  • Diff tools (oasdiff, Optic) show what changed and reach the pull request author. Graphwake reaches the consumer teams it breaks.
  • Docs and changelog tools (Bump.sh) broadcast to everyone. Graphwake sends each alert only to the teams that call the changed endpoint.
  • Contract testing (Pact, Specmatic) needs test code from every consumer. Graphwake works from the OpenAPI specs you already have.

Setup is one CI step or a spec URL. Producers don't maintain a consumer list. Graphwake reads your spec, not your code, and nothing runs in production.

How would you describe the primary audience of your product?

Graphwake's answer:

Engineering organisations with 20+ developers, several teams that depend on each other's APIs, and OpenAPI specs.

  • Buyers: engineering leads, CTOs, VPs of Engineering and platform teams who want fewer incidents caused by cross-team API changes
  • Consumer-team developers: want to hear about a breaking change before it reaches production
  • Producer-team developers: want to ship changes knowing exactly who they will affect

What's the story behind your product?

Graphwake's answer:

I built Graphwake after another team changed an API my app depended on without telling us, and we found out in production.

The change itself was fine. The problem was that the news never reached the people it would break:

  • Producer teams can't keep an accurate list of who calls each endpoint
  • Company-wide announcement channels are too noisy for anyone to read

Graphwake fixes that. Every endpoint knows its consumers, and "every alert has an address"

    In 2014, Pact created an entire engineering discipline. Consumer-driven contract testing — the idea that the API consumer, not the provider, should define what compatibility means — was a genuine breakthrough. It solved problems that... - Source: dev.to / 5 months ago
