The Deno team is joining Cloudflare. Deno Deploy runs six more months, then goes dark — paying customers are promised migration help to Workers. If you host on Deno Deploy, use the calculator below to see your Workers bill before you move.
The short answer: Deno Deploy shuts down around April 2027, six months after the October 9, 2026 announcement. Deno Deploy Pro costs $20/month (5M requests included, then $2/M); Cloudflare Workers Paid costs $5/month (10M requests included, then $0.50/M). A typical 5M-request app drops from $20/mo to $5/mo by migrating — about $180/year saved — but audit Deno KV, Cron, and native dependencies first, because those need replacements (Workers KV/D1, Cron Triggers). Start the migration now, not in March 2027. Prices may change; verify on official pricing pages.
Assumes Deno Deploy Pro ($20/mo base) vs Workers Paid ($5/mo base). Simplified: requests + egress only.
| Deno Deploy Pro | Workers Paid | |
|---|---|---|
| Base price | $20/mo | $5/mo |
| Requests included | 5M / mo | 10M / mo |
| Extra requests | $2 / M | $0.50 / M |
| Egress included | 200 GB / mo | included* |
| Extra egress | $0.50 / GB | — |
| Status | Shutting down ~Apr 2027 | Migration target |
* Workers does not bill egress separately on standard plans. Deno figures from deno.com/deploy/pricing via third-party snapshots (Oct 2026); Workers figures from cloudflare.com. Prices may change — verify before you commit.
Deno Deploy keeps running for six months from the October 9, 2026 announcement that the Deno team is joining Cloudflare — so roughly April 2027. Paying customers are promised migration help toward Cloudflare Workers. The Deno runtime itself gets one more year of monthly bug-fix and security releases, then Deno ends its development of the runtime; Deno stays open source and JSR keeps operating under Cloudflare infrastructure.
For most workloads, yes. Deno Deploy Pro is $20/month with 5M requests included ($2 per extra million). Cloudflare Workers Paid is $5/month with 10M requests included ($0.50 per extra million). A 5M-request app costs $20/mo on Deno Deploy Pro vs $5/mo on Workers — a $180/year saving before egress. Prices may change; verify on the official pricing pages.
Not necessarily from scratch. Cloudflare Workers supports many Node.js APIs via nodejs_compat, and the Deno/Cloudflare joint work targets runtime convergence. But check your dependencies: packages needing unsupported APIs, native binaries, subprocesses, or FFI may fail on Workers. Audit imports before migrating — the checklist above covers the common blockers.
Plan replacements now. Deno KV maps most naturally to Cloudflare Workers KV or D1 depending on your access pattern (KV for high-read/low-write, D1 for relational queries). Deno Cron maps to Workers Cron Triggers. Migrate data early — don't leave the export to the final month.
Migrate sooner. Six months sounds long, but DNS cutovers, data export, and load testing always take longer than planned, and the final months will see everyone migrating at once. Start with a staging deploy on Workers this month, run both in parallel, then cut over traffic gradually.
