What are you trying to do?
A) Fix a broken state — blocks not showing in the editor after install/update, styles missing on the frontend, layout broke after the v4 ApiVersion-3 conversion, an update introduced bugs
B) Build with blocks — containers/layout, headings/buttons, pricing tables, testimonials, post grids/carousels, the Form Builder, the Popup Builder, the Mega Menu, the Header/Theme Builder, 1000+ templates
C) Use Pro/dynamic features — Dynamic Content (ACF/Toolset/Pods/native fields), WooCommerce blocks, Lottie/Spline 3D/scroll animations, White Label, the expanded template library
D) Automate with AI / MCP — set up Nexter Abilities (the built-in MCP server, 115 tools) in Claude/Cursor/VS Code, or use the in-editor AI (ChatGPT/Gemini)
E) Customize/automate via code — performance flags (tpgb_defer_css_js, tpgb_delay_css_js), reading/writing tpgb/-namespaced block markup via the WordPress REST API
F) Pick or compare a plan (Starter / Professional / Studio / Agency Bundle) or weigh Nexter vs other block builders
Free or Pro? Free (WordPress.org) ships ~45+ blocks plus the built-in Form Builder and AI. Theme Builder, White Label, Dynamic Content, WooCommerce blocks, the Popup Builder's advanced types, Lottie/Spline/scroll animations, and the Pro half of the MCP abilities are paid (Professional+ for Theme Builder/White Label).

Step 3 — Nexter platform reference
Read references/platform-guide.md for the full platform reference — blocks/modules, the Nexter Extension + Theme Builder, pricing/plan gates, data model, integration recipes, and code examples. For Nexter Abilities (the MCP server) setup, the tpgb/ block markup, the WordPress REST API approach, and the performance flags, read references/nexter-api-reference.md.
Answer the user's question using only the relevant section. Don't dump the full reference.
Step 4 — Actionable guidance
Focus on the user's specific situation.
Nexter is an all-in-one Gutenberg ecosystem, not a single block library. It's three parts: Nexter Blocks (90+ blocks + in-editor AI), Nexter Extension (50+ site tools + the Theme Builder, security/performance/code-snippets, White Label), and the Nexter Theme. This breadth is its defining contrast with lean block plugins like Stackable/GenerateBlocks — it does ship a form builder, popup builder, mega menu, and header/theme builder.
The standout for makers is Nexter Abilities — a native MCP server. It exposes 115 server-side tools (68 free / 47 Pro, plus 8 workflow skills, button-preset CRUD, and a page-inspection ability) so an MCP client (Claude Desktop, Cursor, VS Code, Windsurf, Cline, Zed, Continue) can compose real, editable tpgb/ Gutenberg blocks from a prompt, screenshot, or URL. Auth is a token you generate in WP admin, scoped to post types + abilities, and every call respects WordPress capability checks. See references/nexter-api-reference.md.
"Blocks not showing in the editor" is usually that you're not in the Gutenberg Block Editor (Classic Editor or another page builder is active), a plugin/JS conflict, or a stale build/cache after an update. Confirm Gutenberg is active, update Nexter, hard-refresh + clear caches, and test with other editor plugins disabled.
The v4 ApiVersion-3 conversion is a known update boundary. v4.7.0 converted all blocks to WordPress "ApiVersion 3." Older tutorials/screenshots may not match, and a major update can introduce regressions — keep a backup/staging copy and a rollback plan before updating a live site.
Performance: the "1 CSS + 1 JS file per page, disabled blocks load nothing" claim is real but not a free pass. Third-party tests still measure ~0.2–0.35s and ~6–9 MiB added per request. For Core Web Vitals, enable Nexter's asset controls (tpgb_defer_css_js / tpgb_delay_css_js), only enable the blocks you use, add caching, and benchmark before/after. For deeper remediation use /sales-seo.
Plan gating drives most surprises.Theme Builder and White Label are Professional+ (5 sites+); Dynamic Content, WooCommerce blocks, advanced popups, and Lottie/Spline/scroll animations are Pro. Confirm the tier before promising a feature, and warn that Pro-only blocks/styling can fall back or stop applying if the license lapses — test on staging.
The automation surface is WordPress + MCP, not a hosted SaaS API. No Nexter REST API, no outbound webhook, no first-party Zapier app. Programmatic surface = the Nexter Abilities MCP server, the WordPress core REST API (blocks are tpgb/-namespaced in post_content, Application-Password auth), the in-editor AI, and PHP option/filter flags. It's GPLv3 (github.com/posimyth/the-plus-addons-for-block-editor) — deeper extension means building from source.

Gotchas
Best-effort from research (2026-06) — review these, especially plan-gated features, the MCP ability counts, and integration details that may be outdated.
All-in-one breadth, but tiered. Form Builder + in-editor AI are free; Theme Builder & White Label are Professional+, and Dynamic Content, WooCommerce blocks, advanced popups, and Lottie/Spline/scroll animations are Pro. Confirm the tier before promising a feature.
Nexter Abilities (MCP) is split free/Pro too. 68 of the 115 abilities are free; the other 47 (CTA banners, timeline, repeater, popup builder, Mailchimp, Lottie/Spline/scroll) require Pro. The MCP endpoint is token-authenticated and scoped — every call still respects WordPress capabilities, and you can disable the endpoint anytime (existing pages stay intact).
The v4.7.0 ApiVersion-3 conversion is a migration boundary. Major updates have introduced regressions; back up + test on staging before updating a live site. Old tutorials may show pre-v4 UI.
Performance claims vs reality. "1 CSS + 1 JS per page, disabled blocks load nothing" is accurate, but third-party tests still show measurable overhead (~0.2–0.35s, ~6–9 MiB). Use tpgb_defer_css_js/tpgb_delay_css_js, enable only needed blocks, and cache.
No hosted REST API, no outbound webhook, no first-party Zapier app. Automate via the Nexter Abilities MCP server and the WordPress core REST API (tpgb/ block markup in post_content). Form leads exit through the form's configured ESP/integration (e.g. Mailchimp).
tpgb/ block namespace is best-effort. It's consistent with Nexter's tpgb_* option flags but not confirmed verbatim in public docs — copy real block markup from a live install rather than hand-authoring attribute keys.
No native A/B testing, heatmaps, or analytics. Nexter builds pages; measurement needs a separate tool (VWO, Microsoft Clarity).

Examples
Example 1: Set up the Nexter Abilities MCP server in Claude to build pages from a prompt
User: "I want Claude to build Nexter landing pages on my WordPress site from a description. How do I wire up the MCP server, and what can it actually do?"
Approach: That's Nexter Abilities, Nexter's built-in MCP server. Install Nexter Blocks (it includes the MCP endpoint + all 115 abilities), connect your Nexter account, enable MCP permissions and scope which post types/abilities the AI may touch, generate a token, and paste the generated MCP config into Claude Desktop. The AI then calls block-add abilities to compose real, editable tpgb/ Gutenberg blocks (containers, headings, pricing tables, testimonials, forms…) — 68 abilities are free, 47 are Pro. It can also recreate a layout from a screenshot or inspect a competitor URL for fonts/colors/media. Every build runs inside a page-type performance budget. Pull exact steps from references/nexter-api-reference.md. Confirm the MCP config snippet against your install — it's generated per-site and wasn't captured verbatim in research.
Example 2: Blocks/styles broke after updating to v4
User: "After updating Nexter, some blocks vanished from the editor and a couple of pages look wrong."
Approach: v4.7.0 converted all blocks to WordPress ApiVersion 3 — a major-update boundary that can introduce regressions. First confirm you're in the Gutenberg Block Editor (not Classic/another builder) and that Nexter is updated; hard-refresh and clear browser + page + object/CDN cache; disable other editor plugins to isolate a JS conflict. If pages are still wrong, roll back from your backup/staging copy and re-test the update on staging. See Troubleshooting.
Example 3: Which plan unlocks Theme Builder and Dynamic Content — and is it lean enough?
User: "I want the Theme Builder, ACF-bound dynamic content, and white-label for client sites. What tier, and will it slow the sites down?"
Approach: Theme Builder and White Label are Professional+ (5 sites); Studio (~$129/yr) is unlimited sites. Dynamic Content (ACF/Toolset/Pods) is Pro. Pricing is best-effort/annual with Lifetime options — verify on nexterwp.com/pricing and note Pro features degrade if the license lapses. On performance: Nexter loads 1 CSS + 1 JS file per page and disabled blocks load nothing, but benchmark — third-party tests still show ~0.2–0.35s overhead; enable tpgb_defer_css_js/tpgb_delay_css_js, turn off unused blocks, and cache. Confirm current tiers in references/platform-guide.md.
Troubleshooting
Nexter blocks don't appear in the editor
Symptom: After installing or updating, Nexter blocks are missing from the block inserter (or some vanished after an update).
Cause: You're not in the Gutenberg Block Editor (Classic Editor or another page builder is active), a plugin/JS conflict, or a stale editor build/cache — often after the v4 ApiVersion-3 conversion.
Solution: Confirm the Gutenberg Block Editor is the active editor; update Nexter to the latest version; hard-refresh and clear browser + page cache; disable other editor plugins to isolate a JS conflict; and confirm the relevant blocks are enabled in Nexter's block manager.
Nexter pages render unstyled or bloat Core Web Vitals
Symptom: A page shows raw/unstyled output, or PageSpeed flags render-blocking CSS/JS and excess weight.
Cause: Cache/optimization plugin stripped or reordered Nexter's assets, or too many blocks/animations are loading without the performance controls enabled.
Solution: Clear page/object/CDN cache and allowlist Nexter's handles in any minify/optimization plugin. Enable Nexter's asset controls (tpgb_defer_css_js / tpgb_delay_css_js), disable blocks you don't use, add caching, and benchmark before/after. For deeper remediation use /sales-seo.
A Pro feature stopped working or an update broke pages
Symptom: Theme Builder / Dynamic Content / Pro blocks stopped applying, or pages broke right after a major update.
Cause: The Nexter license is deactivated/expired (Pro-only blocks/styling fall back), or a major release (e.g. the v4.7.0 ApiVersion-3 conversion) introduced a regression.
Solution: Reactivate/renew the license and confirm it's active on this site; for an update regression, roll back from your backup/staging copy, then re-test the update on staging. Avoid building critical live pages solely on Pro-only blocks without a tested fallback.
