AI inference: BYOK vs FunctionFly managed
Two ways to run AI. Free tier ships with FunctionFly AI (Mercury 2, ~30× cheaper per call than Workers AI). Every tier also supports BYOK — bring OpenAI, Anthropic, Gemini, Groq, or any OpenAI-compatible endpoint. Same quota buckets, same per-token cost, same response envelope. Pick what fits the workload.
How billing works. FunctionFly AI routes through Cloudflare Workers AI by default and Inception Mercury 2 for the diffusion-LLM rung. Free-tier quota bumped 4.8× on 2026-09-02 because Mercury 2 is ~30× cheaper per token than Workers AI (worst-case COGS stays under $1.20/week per free user). BYOK calls go straight to your provider — FunctionFly never sees your key on the wire (Vault ZK mode); metering still applies for rate-limit + budget enforcement.
Always-on agents
Run AI agents around the clock with persistent memory and zero cold starts. BYOK covers LLM costs; platform fee covers compute, memory, and orchestration. Idle time billed at 25% of active rate. See details →
Idle rate is 25% of the active rate. Pool overage charges only apply when you exceed the included context memory pool. Spend caps pause your agents before runaway usage—not after.
Sandbox runtime billing
Every sandbox execution pays for its wall time — billed per second against your wallet, with daily per-tenant caps. Includes python-light, node-lite, node22-typescript, typescript-wasm, ruby, FlyBox, and CCP GPU pods. One row per execution in the ledger; per-second resolution is live observability.

How we compare
Public pricing as of Sept 2026. Headline tiers listed; per-second / per-GB pricing models use the listed pay-as-you-go rates. All plans here are metered SaaS — no per-engineer license fee.
FunctionFly ships every tier with the full stack — functions + State Fabric + Vault + Time Machine + Agents + sandbox per-second billing + 1K+ curated marketplace functions + a 4-level trust verification ladder (L1–L4) — at price points that compete head-to-head with bare-serverless platforms (Vercel, Cloudflare, Lambda) while bundling what those platforms require you to assemble separately: a managed state store, a secrets vault with zero-knowledge mode, agent memory, and an always-on runtime with no cold starts.
Compared to multi-product suites (Render Scale $499/mo, Supabase Team $599/mo, Modal Team $250/mo), FunctionFly Professional at $79/mo covers a comparable feature surface for ~80% less. Enterprise at $299/mo undercuts every comparable suite tier while including MicroVMs, 99.99% SLA options, and a five-nines upgrade at $499/mo.

Frequently asked questions
Do prices include tax?
Listed prices are in USD before applicable taxes. Your invoice will reflect tax rules for your billing address.
What's the difference between BYOK and FunctionFly managed AI?
BYOK (Bring Your Own Key): you wire your OpenAI, Anthropic, Gemini, Groq, or any OpenAI-compatible endpoint. FunctionFly never sees your key on the wire (Vault ZK mode) and the call is billed directly by your provider. FunctionFly managed AI: FunctionFly routes through Cloudflare Workers AI and Inception Mercury 2, paying the upstream cost out of platform margin; you draw from the per-tier weekly quota (Free 500/wk, Starter 420/wk, Pro 2,100/wk, Enterprise 8,400/wk, Agent Enterprise 42,000/wk) or buy credits once you exceed it. Cache hits count as 1/10 of a quota unit, so the effective quota is ~10× on repeated prompts.
Why does Free include FunctionFly AI but paid tiers have lower weekly quotas?
Free uses Inception Mercury 2 (~30× cheaper per-call than Cloudflare Workers AI) for the diffusion-LLM rung. The 4.8× quota bump on 2026-09-02 was safe because worst-case COGS for the entire free tier stays under $1.20/week per user. Paid tiers default to Cloudflare Workers AI for higher reliability + more model options — Starter doesn't get the bump because it's still on Workers AI. Pro and above get the same Mercury 2 model-by-default once AIMODEL_ROUTER_PRIMARY_FUNCTIONS includes your function.
How does the Trust API and verification billing work?
Trust scores, attestations, and verification levels are built into every function — included in your plan. Usage-based components (extra verification drills, deeper audit trail) are metered separately so you only pay for what your agents and policies actually query.
What are always-on agents?
Always-on agents stay resident between requests, maintain persistent memory across sessions, and respond instantly without cold-start latency. Each plan includes a monthly budget of always-on hours and a shared context memory pool; usage beyond that is metered per-minute.
How does always-on billing work with BYOK?
Your LLM costs go directly to your provider via your own API key. The platform charges only for the always-on infrastructure—compute, memory, and orchestration—at $0.05–$0.10 per active minute (depending on plan), with idle time at 25% of that rate.
Can we upgrade or downgrade?
Yes. Move between platform tiers as your traffic and team change; agent plans can be adjusted when your concurrency and call volume need it. Mid-month upgrades include prorated credit for unused hours on the old plan. Annual plans save 20% — or 30% through Nov 30 with the FALL26 promo.
What's the difference between Enterprise, MicroVM Enterprise, Enterprise SLA, and Agent Enterprise?
Enterprise ($299/mo) is the base paid tier with 25M requests, 100 concurrent MicroVMs, and 99.99% SLA. MicroVM Enterprise ($399/mo) is for heavy container workloads — 500 concurrent MicroVMs (5× standard), 16 vCPU and 8 GB per MicroVM (4×), $50/mo included compute budget, and discounted overage rates. Enterprise SLA ($499/mo) upgrades the base Enterprise tier to a five-nines (99.999%) uptime SLA with a 15-minute response time guarantee and a dedicated SLA engineer. Agent Enterprise ($499/mo) is unlimited agents + 42K FunctionFly AI requests/week + 250K memories + all of the Enterprise SLA benefits.
What does Enterprise include?
Volume pricing, custom SLAs, security questionnaires, SSO, and tailored trust policies. Enterprise tier includes L1–L4 verification, 1-year execution logs, 90-day Time Machine with reconciliation, RBAC + Secret sharing, 100K agent memories, Advanced Consciousness (basic ML-driven insights + auto-fixes), 100 concurrent MicroVMs, 1,000 always-on hours/month, and a 10GB context pool. Add MicroVM Enterprise or Enterprise SLA upgrades as needed.
Is there a free trial for paid plans?
Starter and Professional come with a 14-day free trial — no credit card required to start. Enterprise, MicroVM Enterprise, Enterprise SLA, and Agent Enterprise are sold via our sales team (Contact sales) so we can scope SLAs, scale caps, and onboarding to your workload before the contract starts.
How does sandbox per-second billing work?
Every sandbox execution (python-light, node-lite, node22-typescript, typescript-wasm, ruby, FlyBox, CCP GPU pods) is metered per second of wall time. One row per execution is written to the ledger with kind='sandbox_seconds'; per-second resolution lives in the Prometheus histogram and the dashboard's Sandbox Usage panel. Daily per-tenant caps (Free 10 min, Starter 1 h, Pro 5 h, Enterprise 24 h) refuse new admissions when exceeded — in-flight sandboxes always finish. GPU pods (ccp.l4, ccp.a5000, ccp.a100, ccp.h100) are billed at a higher per-second rate to cover upstream provider costs.
What happens when my sandbox daily cap is hit?
New sandbox starts return a typed 'sandbox_daily_cap_exceeded' error. Currently-running boxes continue to completion — the cap is enforced at admission only. The optional SANDBOX_LOW_BALANCE_KILL_THRESHOLD env var enables hard-kill for ops-driven drain scenarios.
Do you offer a discount for non-profits, open-source projects, or startups?
Yes. FunctionFly for Startups offers up to $100K in credits (similar to Render's startup program). Open-source maintainers get a free Enterprise tier for qualifying projects. Non-profits get 50% off any paid tier. Contact sales with your details.
