Optic Is Archived.
Here's a Maintained Alternative.
Optic was a well-loved open-source tool for OpenAPI governance and breaking-change detection — but its repository was archived in January 2026 and useoptic.com no longer resolves. Specway is an actively maintained, hosted documentation platform that keeps breaking-change detection and adds an AI chatbot, custom branding, and analytics.
What changed with Optic
- Optic's GitHub repository (opticdev) was archived as read-only on January 12, 2026.
- useoptic.com no longer resolves; the last release was v1.0.9 in August 2025.
- Optic Labs was acquired by Atlassian (announced April 29, 2024) with intent to fold into Atlassian Compass; by reports that integration never shipped, and there was no formal sunset notice.
If you're searching for where to go next, this page lays out what Optic did well, what carries over, and where the two tools differed.
What Optic Did Well
Credit where it's due. Optic was a genuinely good developer tool, and some of its strengths have no direct equivalent. Knowing what you relied on helps you pick the right replacement.
CI-Native Breaking-Change Detection
Optic's GitHub Action ran on every pull request, diffing the proposed spec against the baseline and failing the build when a breaking change slipped in. That tight CI integration is what teams loved most.
Spec Capture From Real Traffic
Optic shipped a local proxy that observed real HTTP requests and responses, then generated or verified an OpenAPI spec against what your API actually did. This was its standout, genuinely differentiated capability.
Governance Rulesets
Optic supported Spectral-compatible linting and custom rulesets, so teams could enforce naming, versioning, and design conventions across every spec change in code review.
Open Source & Free CLI
The core CLI was MIT-licensed and free, with around 1.5k GitHub stars. It lived where developers already worked: the terminal, config files, and the CI pipeline.
Honest framing: Optic was a CLI and CI tool for spec governance, not a hosted docs platform. In practice the two are largely complementary — the one real overlap is breaking-change detection, which Specway also does, alongside hosting, AI, branding, and analytics that Optic never offered.
Archived CLI Tool vs Maintained Hosted Platform
Specway
Hosted, interactive documentation with breaking-change detection, an AI chatbot, AI-generated content, custom branding, and analytics.
- Hosted, branded interactive docs
- Breaking-change detection & alerts
- AI chatbot & AI-generated content
- Reader-facing docs analytics
- Actively maintained
Best for: Teams that want a supported, hosted docs platform that also flags breaking changes
Optic
Open-source CLI and CI tool for OpenAPI governance, spec capture from traffic, and breaking-change detection. Archived in January 2026.
- CI-native breaking-change detection
- Spec capture from real HTTP traffic
- Open source (MIT, ~1.5k stars)
- No hosted docs portal or branding
- No longer maintained
Was best for: Developers wanting CI-gated spec governance and traffic-based spec generation
Why Teams Move From Optic to Specway
Keep the breaking-change detection you relied on — and gain hosting, AI, and analytics on a maintained platform.
A Maintained Home For Your Docs
Optic's repository was archived as read-only in January 2026, and useoptic.com no longer resolves. Moving to an actively developed platform keeps your documentation workflow supported.
Breaking-Change Detection, Kept
The capability most teams relied on Optic for — catching breaking changes — carries over. We diff every spec version and surface what changed, with alerts before integrations break.
Hosted, Branded, Interactive Docs
Optic produced a locally generated changelog, never a reader-facing portal. We host an interactive documentation site with your branding, a try-it playground, and code samples.
AI On Top Of Your API
Optic had no AI features. We add an assistant trained on your docs plus AI-drafted descriptions, so readers get answers in natural language and your content stays fuller.

Migrating From Optic
A practical path off an archived tool, depending on what you used it for.
Point us at your spec
If you already maintain an OpenAPI spec (the file Optic diffed or generated), give us its URL or upload it. We import it and start hosting interactive docs around it.
Re-enable breaking-change detection
We diff each new version of your spec and flag breaking changes, so the safety net Optic gave you in CI carries over to a hosted, monitored workflow with alerts.
Keep traffic capture separate if you need it
We don't generate specs from HTTP traffic. If Optic's proxy was central to your process, keep a dedicated capture tool for that step and feed the resulting spec to us for hosting and monitoring.
Layer on what Optic never had
Add custom branding, an AI chatbot trained on your docs, AI-drafted descriptions, generated code samples, and analytics on how readers use your API.
Which Approach for Your Situation?
We're honest about the things Optic did that we don't.
Looking for a maintained replacement for Optic
Optic is archived and no longer maintained. We're actively developed and host your docs as a service.
Hosted, branded, interactive API docs
Optic never offered a hosted docs portal. We provide a branded, interactive site with a try-it playground.
Catching breaking changes between spec versions
This is the real overlap. Optic did it in CI; we do it in a hosted platform with alerts. Both approaches are valid.
Generating an OpenAPI spec from live HTTP traffic
Optic's proxy captured real traffic to build or verify a spec. We don't do traffic capture — we work from a spec you already have.
CI-gated spec governance with custom rulesets
Optic's GitHub Action and Spectral-compatible rulesets were built for CI gating. We focus on the hosted docs and monitoring layer instead.
AI chatbot for developer questions
Optic had no AI layer. We include an assistant trained on your docs for natural-language questions.
Analytics on how readers use your docs
Optic had no reader-facing analytics. We show which endpoints and pages developers actually use.
