Ruby Reactor vs dry-transaction vs Trailblazer: Choosing a Ruby Workflow Library in 2026

Four ways to orchestrate business logic in Ruby. One map to find yours. You're building something that involves multiple steps. Charge a card, send an email, update inventory. Simple. Then someone says "What if step 3 fails? What undoes steps 1 and 2?" and suddenly you're evaluating workflow libraries. There are four mainstream approaches in Ruby today — Ruby Reactor , dry-transaction , Trailblazer , and raw Sidekiq jobs. This guide helps you pick the right one — not by ranking them, but by mapping them to the problem you're actually solving. The 30-Second Decision Matrix If you only have 30 seconds, start here: You want... Pick... A simple pipeline — 3-5 steps, top-to-bottom, no parallelism dry-transaction Railway-oriented programming with success/failure tracks, already in the Trailblazer ecosystem Trailblazer A full saga orchestrator — DAG dependency resolution, Sidekiq async, auto-compensation, locks, dashboard Ruby Reactor One-off fire-and-forget jobs, no coordination needed Raw Sidekiq None of these are "better" than the others. They solve different problems. Let's walk through each one. Meet the Libraries dry-transaction (v0.16.0) dry-transaction is a thin, focused gem from the dry-rb ecosystem. It wraps a series of operations in a sequential pipeline with a clean step DSL: class CreateUser < Dry :: Transaction step :validate step :persist step :send_welcome_email def validate ( input ) = # ... def persist ( input ) = # ... def send_welcome_email ( input ) = # ... end Steps run top-to-bottom. If any step returns a Failure , the pipeline stops immediately — no further steps execute. It's a railway under the hood: each step can produce Success(value) or Failure(error) , and the pipeline routes accordingly. What it's great at: Simple, synchronous pipelines. It's the Ruby equivalent of an Either monad chained with bind — clean, predictable, and minimal. If you're already in the dry-rb ecosystem (dry-validation, dry-types, dry-monads), it fits naturally. What it d

The x-tenant-id Pattern: Multi-Tenant API Without Multi-Tenant Complexity

When you're building a multi-tenant SaaS, the first architectural question is usually: how do you keep tenant data isolated? The options range from separate databases per tenant (maximum isolation, maximum cost) to a shared database with row-level filtering (minimum cost, more careful coding required). But there's an equally important question that gets less attention: how does your API know which tenant context a request belongs to? This post covers a pattern we've used in production: a custom request header for tenant scoping, combined with JWT authentication. Simple to implement, easy to audit, and flexible enough to support multi-tenant access from a single user account. The Three Common Approaches 1. Subdomain-based ( tenant.yourdomain.com ) The tenant is encoded in the hostname. Each subdomain routes to the same backend, which extracts the tenant from the Host header. Good: Intuitive, visible in the URL. Bad: Requires wildcard TLS certs, more complex DNS setup, awkward in development, doesn't work for mobile API clients the same way. 2. URL path-based ( /api/tenants/{tenantId}/... ) The tenant identifier is part of every route path. Good: RESTful, self-documenting. Bad: Bloats all route definitions, requires every endpoint to include the tenant segment, makes API versioning messier. 3. Header-based ( x-tenant-id: <id> ) A custom header carries the tenant context. Routes stay clean. The tenant scope is resolved in middleware before the handler runs. Good: Routes stay simple, middleware handles scoping uniformly, works well with JWT auth, easy to test. Bad: Less visible (the tenant isn't in the URL), requires clients to always include the header. We use the header approach. The Implementation The API accepts two forms of auth: A JWT token in the Authorization header — identifies who is making the request A tenant ID in the x-tenant-id header — identifies on behalf of which tenant POST /api/v1/members Authorization: Bearer eyJhbGciOiJIUzI1NiIs... x-tenant-id: ten

I keep finding out about API breaking changes from production errors, so I'm building a changelog watcher

I build products solo. Every single one of them sits on top of somebody else's API — Stripe for payments, OpenAI and Anthropic for AI features, Meta for ads, print-on-demand APIs, map APIs. My code is maybe half of what actually runs in production. The other half belongs to vendors, and it changes whenever they decide it changes. Twice this year the first notice I got about a breaking change was a production error. Not an email, not a warning. An error, and then me digging through the vendor's changelog trying to figure out what they changed and when. The information was public the whole time. It was sitting in a changelog page I never visit, because nobody visits changelog pages until something is on fire. So I'm building the thing I wanted to exist BreakWatch is simple: you tell it which APIs your product depends on, and it reads their public changelogs for you. It fetches each changelog page once a day Diffs it against yesterday's snapshot Classifies the real changes: breaking (endpoint removed, field deprecated, "migrate by September") vs. informational (new feature, docs clarification — stuff you can ignore) Alerts you only when something looks like it will break an existing integration Keeps everything in a searchable timeline, so six months later "what changed on their side right before this broke" takes ten seconds instead of an afternoon No SDK, no credentials, nothing installed in your codebase. It only reads public pages. What I tested this week I ran it against the real changelogs of the ten APIs I'm watching first: Stripe, Twilio, OpenAI, Anthropic, Shopify, GitHub, Slack, Cloudflare, Google Maps and Plaid. Some honest findings: 10/10 scrape cleanly now, but it took fixes. Stripe's changelog page alone is 3.3 MB. SendGrid's standalone changelog doesn't exist anymore (it merged into Twilio's). PayPal's developer site serves a JavaScript shell with an HTTP 404 to anything that isn't a full browser, so it's out until I add rendering. The thing I was most a

Unlocking Digital Identities with Open-Source SSI SDK

why-we-open-sour-c1f013bf.webp alt: Building Digital Identity Tools - Why We Open-Sourced Our SSI SDK relative: false Self-Sovereign Identity (SSI) is a framework that allows individuals and organizations to control their own digital identities and share verified credentials without relying on a central authority. This paradigm shift empowers users with greater privacy and control over their personal data, while also providing robust mechanisms for verifying the authenticity of credentials. What is Self-Sovereign Identity (SSI)? SSI is built around the concept of decentralized identifiers (DIDs) and verifiable credentials. DIDs are unique identifiers that are controlled by the entity they represent, enabling them to manage their own identity data. Verifiable credentials are digital assertions that can be issued by one party and verified by another, ensuring the authenticity and integrity of the information shared. Why did we open-source the SSI SDK? Open-sourcing the SSI SDK was a strategic decision driven by several factors. First, fostering innovation within the community is crucial for advancing the field of digital identity. By making our SDK available to everyone, we encourage collaboration and experimentation, leading to new ideas and improvements. Second, promoting transparency is essential for building trust in digital identity systems. Open-source projects allow others to inspect the codebase, understand how it works, and identify potential vulnerabilities. This transparency helps build confidence in the security and reliability of the SDK. Finally, enabling a broader community to contribute to and benefit from secure digital identity solutions aligns with our mission to democratize access to these technologies. By lowering the barriers to entry, we hope to empower more developers and organizations to adopt and improve upon our work. What are the key features of the SSI SDK? The SSI SDK provides a comprehensive set of tools for building digital identity app
