Bump.sh is strong when API documentation, API hubs, changelogs, and MCP tools are the center of the workflow. Its public pricing highlights docs capacity and MCP tool capacity by plan. Sourced is different: it is an OpenAPI-to-SDKs-and-docs workflow that also includes changelog review, release readiness, package publishing setup, and launch checks.
So the migration question is: do you mainly need API docs plus change visibility, or do you need generated SDK packages and production release control too?
What to inventory from Bump.sh
Collect:
- OpenAPI source
- AsyncAPI source, if present, tracked separately
- hub structure
- documentation branches
- generated changelog history
- breaking-change diff rules
- MCP tools and auth model
- custom domain and logo settings
- GitHub integration
- CI workflow
- redirects and indexed URLs
- API Explorer configuration
As of August 31, 2026, Bump.sh's public pricing emphasizes docs capacity, MCP capacity, and automatic changelog features by plan. Those are useful limits if your team manages a portfolio. Sourced is simpler when SDK package readiness matters more than docs/MCP capacity limits.
Sourced keeps evaluation free: unlimited previews and up to 2 hosted noindex docs review sites. Launch is $99/month per API project for production docs on Sourced-controlled URLs, repo sync, registry readiness/approved publishing, and team review. Scale is $349/month and adds more API projects, more hosted docs sites, more team capacity, and production custom domains.
What changes in Sourced
Sourced should own:
- OpenAPI validation
- docs preview
- TypeScript SDK preview
- Python SDK preview
- package readiness
- semantic changelog review
- MCP starter generation
- release approval gates
- custom-domain docs readiness
The key difference is approval. A good changelog system should not treat every YAML movement as a customer-facing event. Sourced's changelog work should classify semantic API changes, present the candidate notes to a human, and let the user approve or edit the release note before publishing.
Inventory AsyncAPI separately; Sourced's SDK/docs/changelog workflow requires a canonical OpenAPI 3.x spec, so AsyncAPI-only projects need conversion first.
Migration steps
- Export the OpenAPI spec Bump.sh deploys.
- Export current changelog entries and route history.
- Upload the spec to Sourced.
- Generate docs and SDK previews.
- Compare API reference coverage.
- Run a semantic OpenAPI diff, ignoring non-semantic YAML ordering noise.
- Review generated changelog candidates.
- Generate MCP starter output only for the operations that should be agent-callable.
- Build redirects for old docs and changelog URLs.
- Cut over production docs only after approval.
Changelog migration rule
Keep old changelog entries as historical truth. Do not rewrite them to match the new generator. For future entries, classify:
- breaking: removed endpoint, new required request parameter, request body requiredness change, auth change
- added: new endpoint, new optional parameter, new response field
- fixed: docs-only clarification, schema description fix, example correction
- internal: formatting, ordering, tag reorder, description cleanup with no API behavior change
Sourced promotes operation-level removals/additions, required params, request body requiredness, security changes, and whole-schema changes into review. Field-level breaking classification is reviewer-assisted until deeper schema diffing lands. Only breaking, added, and meaningful fixed entries should show up in customer-facing notes.
Prompt for an AI agent
Migrate our Bump.sh API docs/changelog/MCP workflow to Sourced.
Inventory OpenAPI source, any AsyncAPI source separately, docs hubs, branches, changelog history, breaking-change rules, MCP tools, custom domain, redirects, GitHub integration, CI, and API Explorer behavior.
Generate Sourced docs, TypeScript SDK, Python SDK, semantic changelog candidates, MCP starter, and release-readiness previews.
Compare route coverage, changelog semantics, tool names, SDK method names, auth, package metadata, and noindex/index behavior.
Ignore non-semantic OpenAPI ordering changes. Do not publish, change DNS, or index previews without explicit approval.
Bottom line
Migrate from Bump.sh to Sourced when SDK packages and release readiness are now as important as API docs and changelogs. Stay with Bump.sh if API hubs, changelog automation, and MCP capacity are the main thing you are buying.
