Where users complain and no one leads

No complaint theme was raised about 2 or more companies yet; 15 themes were raised about one company each and stay out — one company's complaint is about that company.

A theme enters when users raised it about 2 or more companies — one company’s complaint is about that company. The pairing is word overlap between the theme and what companies declare on their own pages, with the shared words shown; a theme with no match is unanswered in the declared names, not missing from every product. Nothing here is scored or ranked.

  • Solo builders adding sign-inFACTSep 30, 2026

    Free-tier MAU thresholds vary widely across providers commonly recommended to solo builders: Supabase Auth is free up to roughly 50,000 MAUs with a $25/month Pro plan covering 100,000 MAUs, Firebase Auth's Spark plan is free to about 50,000 MAUs, and Clerk offers a free tier of about 10,000 MAUs before costs rise sharply at scale (estimated ~$1,825 at 100K MAUs).

    Pricing thresholds directly affect which provider a solo builder picks as their project grows past hobby scale.

Each row is the last pricing change the reading recorded for that company, with its date, its tag and its source — a company’s own page is its claim about itself. Forge keeps no price list and computes no price: there is no average, no cheapest and no ranking here.

Money into this sector

1 round recorded across 2 read quarters. 0 of them stated an amount; the sums are floors over those, per currency and per tag, never combined. The number of companies read moved from 7 to 1 across the span, so a change in the count is partly a change in what was read.

A round is counted from a dated, sourced ledger entry tagged FACT or COMPANY CLAIM. A sum is a floor over the rounds that stated a figure, never a valuation, and two currencies are never added. The label over a bar is how many companies were read that quarter — a taller bar over a bigger denominator is not more money.

How big this market is, as its publishers state it

No market-size figure has been recorded for this level yet. Not read is not zero.

Research-house estimates for this sector, carried side by side under each house’s own name. Estimates of one market can differ several-fold; none is averaged, and none is Forge’s.

No publisher is named for this level yet, so there is nothing to read from. Publishers are authored in the taxonomy and arrive with a deploy.

What each week held

12 weeks, 1 company read in the first week that was read and 7 in the last — so a count that rose partly because the number read rose too. 10 weeks with nothing read at all, shown empty rather than as quiet.

The bar is observed claims in that week; the label over it is how many companies were read in it. A dashed marker is a week where nothing was read at all — not a quiet market. Inferences and failed reads are in neither.

Who is watched

Ordered by how much each said in the last seven days. A company Forge has not read yet says so — it is not a quiet one.

  • Solo builders adding sign-inCOMPLAINTUSER OPINIONSep 30, 2026

    A recurring theme in older Indie Hackers threads is concern about vendor lock-in and difficulty migrating away from a managed auth provider once adopted, alongside worry about losing UX flexibility over time.

    Lock-in concern is a persistent friction point that could push some builders toward OSS options like NextAuth or Better Auth.

    Clerk, Firebase Auth, Supabase Auth, Kinde, Auth0, Better Auth, NextAuth, and Keycloak are positioned along a spectrum from easiest/most managed to most control/self-hosted, with Clerk and Firebase cited as the top picks for beginners and side projects due to pre-built sign-in components and zero-backend setup.

    Establishes which tools solo builders are actively comparing when adding sign-in, useful as a baseline for tracking future positioning shifts.

  • Solo builders adding sign-inDISCOURSEUSER OPINIONSep 30, 2026

    Across multiple recent dev-blog comparisons and HN/Indie Hackers threads, the prevailing advice for solo builders is to avoid building auth from scratch. One 2026 guide states: "Stop building your own auth" and frames it as a fully solved problem not worth spending time on.

    Solo builders evaluating auth are likely to default to managed services rather than custom builds as the baseline expectation.

  • Auth pricing at scalePOSITIONINGCOMPANY CLAIMSep 30, 2026

    BASELINE: Auth0's own pricing page now markets itself as 'The first and last auth platform you'll ever need' with 'Flexible pricing for all your apps and AI agents from user 1 to 1,000,000+,' including new free-tier additions like '1 Enterprise Connection,' 'Self-Service SSO,' and 'SCIM.'

    Signals Auth0 is repositioning toward AI-agent authentication and loosening some enterprise-feature gates on the free tier, which may blunt some cost-cliff complaints for small teams needing basic SSO.

    auth0.com/pricing
  • Auth pricing at scaleDISCOURSEUSER OPINIONSep 30, 2026

    BASELINE: Comparison content across multiple independent sites consistently frames Clerk and Supabase Auth as the lower-cost, better-DX alternatives to Auth0 at scale — one analysis states Auth0's per-MAU pricing model makes it expensive compared to usage-proportional competitors, and another notes at 100k MAU Supabase costs roughly $25/month while Auth0 could run $500-$3,000+.

    Indicates the 'Auth0 is expensive at scale vs Clerk/Supabase' argument has moved from a niche complaint into a standard, repeated framing across the comparison-content ecosystem, relevant to anyone evaluating auth vendor lock-in risk.

    Signals a recurring third-party sighting of pricing-predictability complaints that could cross into mainstream buyer concern for enterprise renewals.

    BASELINE: The developer/startup community has dubbed Auth0's cost escalation as its user base grows the 'growth penalty,' with one company reporting its bill jumped from $240/month to $3,729/month as its user base grew only 1.67x.

    Affects high-growth consumer/freemium apps most, where MAU growth outpaces revenue, making Auth0 disproportionately expensive relative to value delivered.
