FREE WORDPRESS PLUGIN
Block Source Editor
Edit the native source of one selected Gutenberg block — without switching the entire page to Code Editor.
No telemetry · No frontend assets · No external service dependency
FOCUSED SOURCE ACCESS
Work on the block you actually need.
Select a block, open Edit block source, make the change and apply it back through the WordPress block editor.
- Selected block and nested blocks
- Native Gutenberg serialization
- Validation before replacement
1 block
Edit only the selected Gutenberg block tree.
Native
Work directly with WordPress block serialization.
Free
Focused Gutenberg source editing without a frontend footprint.
WHY IT EXISTS
The middle ground between visual editing and full-page source.
Sometimes the visual editor hides the detail you need. WordPress Code Editor solves that by exposing everything. Block Source Editor gives you a narrower option.
Keep the rest of the document out of the way.
Open the source for the selected block, including its nested blocks, make the change and return directly to the normal Gutenberg workflow.
Useful when: inspecting serialized attributes, repairing block markup, changing nested structures or making source-level edits that are awkward in the visual interface.
EDITOR FEATURES
A source workspace built around the selected block.
The scope stays deliberately narrow while still giving developers practical control over Gutenberg source.
Source editing workspace
Edit Gutenberg block markup in a dedicated source interface without exposing the entire document.
Nested blocks included
Select a Group, Columns block or another container and work with the complete block tree nested inside it.
Validation before replacement
Edited source is checked before it replaces the selected block, reducing the risk of applying malformed block source.
Selected scope
The editor starts from the block you selected instead of loading the entire post source.
Native block source
Work with the same serialized block structure WordPress itself stores and parses.
Editor-only footprint
No Block Source Editor assets are required on the public-facing website.
HOW IT WORKS
From visual block to source and back.
The workflow stays inside Gutenberg and takes only three steps.
STEP 01
Select a block
Choose the block you want to inspect or modify in the editor or List View.
STEP 02
Open block source
Open More Options and choose Edit block source.
STEP 03
Edit and apply
Make the source change and apply the validated result back to Gutenberg.
FREE OR PRO
Start with the block. Go further when you need to.
Block Source Editor stays focused on selected blocks. Source IDE Pro extends the source-editing concept to complete WordPress documents.

FAQ
Block Source Editor questions
Does Block Source Editor edit the complete post source?
No. It intentionally works with one selected block and the nested block tree inside it.
Can I edit nested blocks?
Yes. Selecting a container such as Group or Columns exposes that selected block together with its nested blocks.
What happens if the source is invalid?
The plugin refuses to apply source it cannot safely parse and validate, leaving the existing block unchanged.
Does it send my content anywhere?
No. Block Source Editor contains no telemetry and does not send your block source to REEID or another external service.
When should I use Source IDE Pro instead?
Use Block Source Editor when you need precise access to one block tree. Source IDE Pro is designed for broader source work on complete WordPress documents.
