Mintlify pricing

About

Mintlify is the AI-native developer documentation platform. You point it at a Git repo, write in MDX, and it publishes fast, searchable, beautifully themed docs — with an AI assistant, a writing agent, workflows, and an MCP server baked in so both humans and AI agents can read your docs. It is the docs layer behind a long list of developer-facing companies: Perplexity, X, Cognition, Together AI, Replit, Lovable, Anaconda, Laravel, Kalshi, Loops, and Fidelity.

The company was founded by Han Wang and Hahnbee Choi and went through Y Combinator’s W22 batch. In April 2026 it raised a $45 million Series B at a $500 million valuation, led by Andreessen Horowitz and Salesforce Ventures, with Bain Capital Ventures, Y Combinator, HubSpot Ventures, and others — bringing total funding to $67 million. Mintlify says it serves 20,000+ companies and that its docs reach more than 100 million people a year. The headline metric that explains its pricing direction: roughly 50% of traffic to Mintlify-hosted docs now comes from AI agents rather than humans.

Pricing summary : How Mintlify’s pricing model works

Mintlify’s pricing is deliberately simple at the top and metered underneath. There are two public tiers:

• Starter — $0 (free). For individuals and small teams. You get the full platform: custom domain, web editor, authentication (Mintlify Auth), the AI assistant, the writing agent, workflows, and the MCP server. It starts with a 14-day trial, no credit card required, and 5,000 AI credits.
• Enterprise — Contact us. For scaling and global teams. Everything in Starter plus role-based permissions, SSO, a performance SLA, agent analytics, advanced insights, enterprise security and legal review, custom SLAs, and migration support.

The meter sits on AI usage. The assistant, writing agent, and workflows consume credits: every account gets 5,000 credits included, and usage beyond that is billed at $0.01 per credit, with tiered credit packages available for heavier users. You can set a hard cap on credits so AI spend can’t surprise you.

What makes this different: Mintlify gives away the entire publishing platform for free and only charges where AI inference actually costs it money — the credit meter — or where you need enterprise governance. That is the opposite of the legacy docs-tool playbook (seat-priced tiers gating features like custom domains). It collapsed its earlier Pro and Growth self-serve tiers into this one free plan, betting that free distribution plus AI-credit metering plus Enterprise upsell beats a middle-of-the-funnel rate card.

Pricing by product

AI features are metered identically regardless of tier: 5,000 credits included, then $0.01 per credit, with tiered packages for volume.

Sales motions across products: self-serve and product-led for Starter (sign up, ship docs, pay only for AI overage); sales-led for Enterprise, which is quoted, not listed.

Hidden costs : What Mintlify users actually pay

The base platform is genuinely free, so the only variable cost on Starter is AI credit consumption. Where bills grow is heavy use of the assistant, writing agent, and workflows once you blow past the 5,000 included credits — at $0.01 per credit, an AI-heavy docs site that lets agents answer thousands of questions a month can run up a real overage line. The good news: there is a hard-cap control, so this is opt-in spend rather than a surprise.

The real “hidden cost” is not on the rate card at all: it’s the jump from free Starter to custom-quoted Enterprise once you need SSO, RBAC, or a performance SLA. There is no published middle tier, so any governance requirement puts you into a sales conversation.

Pricing evolution : Mintlify pricing history and changes

Cadence

Tracked range: 2024–present. The current live capture (2026-06-15) is the primary evidence; legacy tier figures are described approximately, not asserted as current rates.

Notable changes

• 2024–2025 — Mintlify ran a multi-tier self-serve rate card: a free Hobby tier, a Pro tier (reported at roughly $150/month with capped editor seats), and a Growth tier (reported at roughly $550/month with a custom domain and more editors plus per-editor add-ons), alongside custom Enterprise. These legacy figures are cited as approximate and historical, not as a current rate-card line.
• 2026-04-14 — Series B: $45M at a $500M valuation (a16z, Salesforce Ventures). Around this period Mintlify simplified self-serve.
• 2026-06-15 — Live pricing page shows only Starter ($0) and Enterprise (Contact us), with 5,000 AI credits included and $0.01/credit overages. The Pro and Growth self-serve tiers are gone, replaced by a free Starter and a credit meter.

What’s unique : Mintlify’s distinctive pricing mechanics

1. The whole platform is free; only AI is metered. Custom domains, web editor, auth, and the MCP server — the things competitors gate behind paid seats — are all in the $0 Starter plan. Mintlify charges where its own marginal cost lives: AI inference, via the $0.01 credit meter.

2. Credits with a hard cap. AI features bill in credits ($0.01 each, 5,000 included) and you can set a hard spend cap. That converts the usual usage-pricing anxiety (bill shock) into opt-in, bounded spend — a deliberate trust move for a free-led funnel.

3. No published middle tier. There’s a clean two-step ladder: free Starter, then custom Enterprise. Mintlify removed the in-between Pro/Growth pricing entirely, betting that governance needs (SSO, RBAC, SLA) are the real upsell trigger, not feature-gating mid-market teams.

Strengths & weaknesses

Billing UX : Mintlify billing controls and transparency

• Billing controls — Credits can be hard-capped, so AI overage spend is bounded by you, not discovered after the fact. Tiered credit packages let heavier users pre-buy at better rates.
• Usage visibility — AI usage is metered in credits against the 5,000 included allotment; agent analytics and advanced insights (Enterprise) expose how AI features are being consumed across your docs.
• Payment options — Starter requires no credit card to start (14-day trial). Enterprise is invoiced via a sales quote. Mintlify also routes 1% of subscription revenue to carbon removal via Stripe Climate, signalling Stripe-based billing.

Strategic wins : Why Mintlify’s pricing decisions worked

1. Free distribution as the moat

By making the full platform free, Mintlify turned pricing into a distribution engine: developers ship docs at $0, those docs rank and get cited, and Mintlify becomes the default. With ~50% of docs traffic now coming from AI agents, owning the docs surface is strategically valuable beyond the subscription line. See usage-based pricing strategy.

2. Pricing aligned to actual cost

Metering AI in credits ($0.01 each) ties revenue to the one thing that genuinely costs Mintlify money — inference — instead of seats. That keeps the free tier economically sane and makes the model scale with value delivered. Related: how AI companies are shifting from per-user licenses and outcome-based pricing trends.

3. Collapsing the funnel

Removing Pro and Growth simplified the buying decision to free-or-Enterprise, reducing friction for self-serve and concentrating sales effort on accounts that need governance. See choosing the right usage metric for why credits fit AI features better than seats.

Areas to improve : Gaps in Mintlify’s pricing approach

1. The free-to-Enterprise gap

There’s no published step between $0 and “Contact us.” A growing team that needs SSO or RBAC — but isn’t a true enterprise — has no self-serve path and lands in a sales cycle. A published mid-tier (the role the old Growth plan filled) would smooth that cliff. See bill shock and cost unpredictability.

2. Credit forecastability

Credits are transparent per-unit ($0.01) but hard to forecast in aggregate: how many credits does an AI assistant answering customer questions actually burn? Clearer per-action credit costs (per assistant query, per workflow run) would help teams budget before they hit overages.

3. Enterprise opacity

Enterprise is entirely quote-based. Even an indicative starting price or a published list of what drives the quote would help buyers self-qualify rather than enter a black-box negotiation.

Key takeaways

1. Mintlify gives the platform away and meters AI. Starter is a real $0 with custom domain, editor, auth, and MCP server; only AI features (5,000 credits, then $0.01/credit) cost money.
2. The rate card collapsed to two tiers. Pro ($150/mo) and Growth ($550/mo) are gone; it’s free Starter or custom Enterprise.
3. Credits, not seats, are the meter. AI usage bills at $0.01/credit with a hard cap — aligning price to inference cost and defusing bill-shock anxiety.
4. Enterprise is governance-gated. SSO, RBAC, SLAs, and advanced auth live only behind a sales quote.
5. Free distribution is the strategy. With ~50% of docs traffic from AI agents and 20,000+ customers, owning the docs surface matters more than middle-tier subscription revenue.

UBP implications

1. Meter the cost driver, not the user. Mintlify prices AI credits because inference is its marginal cost; seats would have mis-aligned price and cost. Pick the meter that tracks your real COGS.
2. Pair usage metering with a hard cap. The $0.01-per-credit-plus-hard-cap pattern shows how to offer usage pricing without scaring buyers — bounded, opt-in overage beats open-ended metering.
3. Free + usage + enterprise can replace a tier ladder. Collapsing mid-tiers into a free base plus a usage meter plus custom Enterprise is a viable structure when distribution is the goal and AI is the variable cost.

Bottom line

Mintlify made a clean pricing bet: give the entire documentation platform away for free, meter only the AI features that actually cost it money ($0.01 per credit, 5,000 included, with a hard cap), and reserve everything else for a custom Enterprise quote. The old Pro ($150/mo) and Growth ($550/mo) self-serve tiers are gone. For most teams that means Mintlify is effectively free until you either go AI-heavy or need enterprise governance — a model built for distribution in a world where half your docs readers are AI agents.
