What a Customer Feedback Portal actually does
Provides a branded public feedback board where users submit, vote on, and discuss product feedback, with AI auto-clustering of duplicate requests and PM response drafting.
A white-label customer feedback portal is a hosted subdomain (feedback.yourproduct.com) where users submit feature requests, bug reports, and product feedback, vote on existing submissions, and track status updates. The AI layer adds three key capabilities: automatic deduplication clustering (grouping semantically similar requests using text-embedding-3-large), sentiment and emotion tagging per submission, and AI-drafted PM responses that maintain brand voice.
The market in 2026: Featurebase Pro at $29/mo with custom-domain white-label is the most honest cheap option in this category. Canny at $79/mo does not include custom-domain WL. Sleekplan at $39/mo has WL features. The DIY case: if you're managing feedback portals for 10+ clients, building a multi-client platform with Lovable for $10K pays for itself vs $29/mo × 10 clients = $290/mo = $3,480/year.

The AI stack
The feedback portal AI stack is commodity-simple — Haiku for classification, embeddings for deduplication, Sonnet for PM response drafting. Total AI cost at 1,000 submissions/month is under $1.
Duplicate detection and clustering
Groups semantically similar feedback submissions (multiple users reporting the same bug or requesting the same feature) without manual review
text-embedding-3-large + cosine similarity
$0.13 / M tokensProduction feedback portals where duplicate detection quality affects PM workflow efficiency
text-embedding-3-small + cosine similarity
$0.02 / M tokensBudget-conscious portals or initial deployment before scaling
Our pick: text-embedding-3-small for initial deployment; upgrade to text-embedding-3-large if duplicate detection quality is a key selling point. The cost difference is negligible at typical portal volumes.
Sentiment and category tagging
Tags each submission with sentiment (positive/neutral/negative), emotion, and primary category (bug, feature, UX, performance, billing)
Claude Haiku 4.5
$1 / $5 per M tokensAll feedback classification
DeepSeek V4 Flash
$0.14 / $0.28 per M tokensHigh-volume portals with US-only users where cost matters
Our pick: Claude Haiku 4.5 — at $0.0005/submission, it's effectively free. Quality is worth the marginal cost.
PM response drafting
Drafts professional PM responses to feedback submissions in the product's brand voice
Claude Sonnet 4.6
$3 / $15 per M tokensAll PM response drafting — quality and brand voice matter for customer relationships
Our pick: Claude Sonnet 4.6 for PM responses. The total monthly cost at typical portal scales is under $2 — use the best model.
Reference architecture
The feedback portal architecture is simple: submissions → embedding → clustering → classification → PM response queue. The main engineering complexity is the deduplication UI — showing potential duplicates before a new submission is added requires sub-second similarity search on the portal's client side.
User submits feedback on public portal
Public Next.js page (no auth)Feedback form: title, description, category tag (optional). On submit: store in posts table. Trigger background job for AI processing.
Duplicate detection shown during submission
Supabase Edge Function + text-embedding-3-smallAs user types title, debounced request embeds partial title and searches pgvector for top 3 similar existing posts. Displayed as 'Similar existing requests' below the form. Cost: ~$0.0001 per search.
Post-submission AI processing batch
Supabase trigger + Edge FunctionOn INSERT to posts: (1) embed full title + description, store in post_embeddings; (2) call Haiku for {sentiment, category, duplicate_candidate_id}; (3) if duplicate_candidate_id returned, link posts in duplicates table for PM review. All async — user doesn't wait.
PM views incoming submissions in admin dashboard
Next.js admin (auth required)Dashboard shows: unreviewed posts, potential duplicate clusters, sentiment distribution, top-voted items. PM can: merge duplicates, update status (reviewing/planned/in-progress/shipped/declined), draft response.
AI response draft generated on PM request
Supabase Edge Function + Claude Sonnet 4.6PM clicks 'Draft Response.' Sonnet receives: post title, description, PM's response intent (planned/not-planned/needs-info), and brand voice config. Returns a 2–4 sentence response draft. PM edits and publishes. Cost: ~$0.01 per draft.
Trend reports generated weekly
Supabase pg_cron + Sonnet 4.6Weekly: aggregate top 10 submission clusters by vote count + recency. Sonnet generates executive summary of key product feedback trends. Emailed to PM team and stored in weekly_reports.
Estimated cost per request
~$0.0001 per real-time duplicate check; ~$0.0005 per classification; ~$0.01 per PM response draft. At 500 submissions/month and 50 PM response drafts: ~$0.75/month total AI cost.

Cost model for a multi-client agency managing feedback portals for 10 SaaS clients, each with ~100 submissions per month.
Estimated monthly cost
$45.16
≈ $542 per year
Calculator notes
- At 10 portals × 100 submissions = 1,000 submissions/month: AI costs ~$0.60. Infrastructure ($45/mo) is 75x more than AI cost.
- Featurebase comparison: 10 portals × $29/mo = $290/mo vs $45/mo infrastructure. Custom build saves $245/mo = $2,940/year. Build cost of $10K pays back in 3.4 years.
- For 25 clients: $290/mo Featurebase savings → payback in 13 months.
- For a single SaaS product: Featurebase at $29/mo is cheaper than building (payback would be 34+ years). Do not build for a single product.

Starter prompt
Build a white-label AI customer feedback portal using Vite + React + TypeScript + Tailwind CSS with Supabase backend. Public-facing features (no auth): 1. Feedback board: list of posts sorted by vote count (hot), newest, or status. Each post shows: title, short description, vote count, category badge, status badge (under_review|planned|in_progress|shipped|declined). 2. Vote: upvote button on each post. One vote per session (track by localStorage fingerprint). Increment votes count. 3. New submission form: title (required), description, category (dropdown: Bug Report|Feature Request|UX Feedback|Performance|Other). Before submitting, call a Supabase Edge Function to search pgvector for top 3 similar existing posts — display as 'Similar requests.' User can click to vote on an existing one instead. 4. Post detail page: full description, all comments, status history, and official PM response (if posted). Admin features (auth required — Supabase Auth email/password): 5. Admin dashboard: list of new/unreviewed posts with AI sentiment badge and duplicate-detection flag. 6. Post management: update status, mark as duplicate (merges into parent post), draft PM response ('Draft Response' button calls Sonnet 4.6 Edge Function with post content and returns 3-sentence response). 7. Weekly trends view: top 5 feature clusters, sentiment distribution, submission volume chart. 8. Brand config: brand_name, primary_color, logo_url, welcome_message. Database: posts (id, title, description, category, status, votes, official_response, created_at), post_embeddings (post_id, embedding vector), post_classifications (post_id, sentiment, duplicate_candidate_id), votes (post_id, session_fingerprint), comments (post_id, content, created_at), brand_config. AI: on INSERT to posts → embed with text-embedding-3-small → classify with Haiku 4.5 → search for duplicates → store results. Async, post shows immediately. Secrets: ANTHROPIC_API_KEY, OPENAI_API_KEY.

Follow-up prompts (run in order)
- 1
Add multi-tenant support: add a portals table (portal_id, name, slug, brand_config). All posts, votes, and comments scoped to a portal. Public URL: [slug].yourplatform.com or custom domain. Admin creates and manages multiple portals. RLS policies enforce isolation.
- 2
Add Slack integration: when a new post is submitted with sentiment=negative or votes>10, post a Slack notification to a configurable webhook URL (stored per portal in brand_config). Include: post title, category, vote count, and sentiment. Admin can dismiss via Slack button.
- 3
Add email digest: weekly pg_cron sends a PM digest email (via Mailgun) listing: new submissions count, top-voted feature requests, top bug reports, and 1-paragraph AI executive summary from Sonnet 4.6.
- 4
Add custom domain support: Vercel custom domain per portal. PM enters their custom domain in brand config, your platform displays instructions to add a CNAME record pointing to your Vercel deployment. Test with Vercel's domain verification API.
Expected output
A working branded feedback portal at your-domain.vercel.app where users submit feedback, vote on requests, and see status updates — with AI duplicate detection showing similar requests before submission, and a PM dashboard for response drafting.
Known gotchas
- !pgvector cosine similarity search for real-time duplicate detection requires proper HNSW or IVFFlat index on the embedding column — without an index, similarity search on 10,000+ posts will be slow. Add: CREATE INDEX ON post_embeddings USING hnsw (embedding vector_cosine_ops);
- !Voting with localStorage: localStorage fingerprinting for anonymous vote deduplication is easy to circumvent. For production, require email verification before voting, or accept that vote counts are approximate for anonymous portals.
- !Custom domain setup: Vercel's custom domain verification requires the user to add a CNAME or A record. Build clear instructions into the admin UI — most non-technical PMs have never set a DNS record.
- !Featurebase at $29/mo is the honest comparison: before building, calculate whether your use case justifies the build. For a single product, Featurebase wins on time and simplicity. For a multi-client agency with 10+ portals, the math shifts.
Compliance & risk reality check
Feedback portals have minimal compliance overhead — the main considerations are GDPR consent for EU users and accessibility for the public form.
GDPR — user-submitted feedback data
User-submitted feedback may contain personal data (names, company names, email addresses in free text). Under GDPR, this is personal data if it identifies or can identify an individual. The lawful basis is typically legitimate interest (improving the product). Users have the right to request deletion of their submissions.
Mitigation: Include a privacy notice link on the submission form. Build a 'Delete my submission' function accessible to submitters. For EU portals, ensure Supabase data is hosted in EU regions.
Accessibility — WCAG 2.2 AA on public form
The public feedback form and board must be accessible to users with disabilities. This includes keyboard navigation, screen-reader compatibility, and proper color contrast.
Mitigation: Run Lighthouse accessibility audit before launch. Ensure form fields have labels, error messages are clear, and the voting button is keyboard-accessible.
Build vs buy: the real math
4–6 weeks
Custom build time
$10,000–$18,000
One-time investment
3+ years vs Featurebase (1 portal); 13 months (25 portals)
Breakeven vs buying
Featurebase Pro at $29/mo per portal is the honest comparison. For 1–9 portals: Featurebase wins on time and simplicity (build payback is 3+ years). For 10 portals: payback is 3.4 years — marginally better. For 25 portals: $725/mo vs $45/mo = $680/mo savings = 18-month payback on a $10K build. The custom build is clearly justified only at 25+ portals under management. The AI differentiation (deduplication clustering, PM response drafting) is a genuine feature advantage over Featurebase — but test whether clients actually pay more for it before building.

Frequently asked questions
How much does it cost to build a white-label AI feedback portal?
A Lovable build costs $25 tools + $5 API credits. Operating costs at 10 portals × 100 submissions/month run about $45/month total (mostly infrastructure). RapidDev builds multi-tenant portals with advanced AI clustering in the $10K–$18K range. Featurebase Pro at $29/mo per portal is the honest alternative for fewer than 25 portals.
Is Featurebase really cheaper than building?
For 1–9 portals: yes, Featurebase at $29/mo is cheaper for at least 3 years vs a $10K custom build. For 25 portals: $725/mo vs $45/mo custom ops = $680/mo savings = 15-month payback on a $10K build — at that point, building starts to win. The honest threshold is about 15–20 portals under simultaneous management.
What does 'white-label' mean for Featurebase vs Canny?
Featurebase Pro at $29/mo includes custom domain (feedback.yourproduct.com) and brand removal. Canny's Starter at $79/mo does NOT include custom domain — you get a canny.io subdomain. Canny Business at $399/mo includes full custom-domain white-label. Featurebase is genuinely the most affordable true white-label feedback portal on the market in 2026.
How does AI deduplication help a product team?
Without deduplication, the same feature request gets submitted 50 times as isolated posts. A PM has to manually identify and merge them. AI deduplication (embedding similarity search) groups semantically similar posts automatically — showing users similar existing requests before they submit, and clustering similar posts in the admin view. For a mature product with 5,000+ feedback items, this turns a 4-hour weekly deduplication task into a 15-minute review.
Can RapidDev build a custom feedback portal for my agency?
Yes — RapidDev builds multi-tenant feedback portals with AI deduplication clustering, sentiment tagging, PM response drafting, custom domains per portal, and Slack/email integration. Standard builds run $10K–$18K and ship in 4–6 weeks. Our recommendation: start with Featurebase at $29/mo per portal until you hit 15+ simultaneous portals, then commission the custom build.
