Listmonk alternatives (2026)
Listmonk: The self-host newsletter stack. AGPL, fully free, you run the mail.
Its Catch: AGPL-3.0 is copyleft — network use means you share modifications.
Below: 8 free or free-tier tools from the same category (notification tools), free and open source first, then the closest match by shared tags. Each keeps its own Catch.
Free / OSS · Apache-2.0 · 34.9k GitHub stars
VerdictThe notification CLI that is actually free. curl it from a cron job.
CatchAnonymous topics are passwords — guessable names leak other people's alerts. Public ntfy.sh rate-limits; reserved topics need Pro. Dual license means you pick Apache-2.0 or GPLv2, not Apache-only.
Free / OSS · BSD-2-Clause · 17.6k GitHub stars
VerdictThe notification Swiss Army CLI. BSD, no meter, no product SKU.
CatchNot a hosted inbox. There is no pricing page — that is the path. You bring every backend (SMTP, Slack tokens, Twilio). This is a notifier, not ntfy and not Novu.
Free / OSS · OSS/MIT · 16.1k GitHub stars
VerdictMIT push you self-host. No ntfy.sh-shaped public instance; Android is the client.
CatchNo public hosted twin like ntfy.sh. Android-first client, not a public pub-sub host. Distinct from ntfy (public ntfy.sh + dual license) and Apprise (CLI fan-out, no inbox).
Free / OSS · GPL-3.0 · 10.8k GitHub stars
VerdictGPL-3.0 marketing automation. Self-host free; hosted trial is not forever-$0.
CatchMarketing automation — not Listmonk newsletter/tx alone. Hosted 14-day trial is NOT the free path; self-host is. Distinct from Listmonk.
Free / OSS · Freemium · 9 GitHub stars
VerdictAGPL Workers push. Self-host $0; Hosted Free is capped — ignore Pro.
CatchBYO APNs+FCM on Cloudflare Workers — not ntfy/Gotify self-host pub/sub, not Novu workflow orchestration. Server is AGPL; pitch self-host or Hosted Free caps. Distinct from ntfy, Gotify, and Novu.
Free / OSS · AGPL-3.0 · 283 GitHub stars
VerdictMIT Go push relay. Self-host free; not Edgepush AGPL Workers.
CatchEdgepush server is AGPL; Shove is MIT end-to-end Go. Device-push relay — not ntfy/Gotify general pub/sub, not Novu multi-channel workflows. Distinct from Edgepush, ntfy, Gotify, and Novu.
Free / OSS · Freemium · 3.2k GitHub stars
VerdictMIT Android SMS gateway. Hosted Free is capped; keep the phone online.
CatchAndroid phone must stay online; not iOS. SMS hole vs Twilio trials — you own the handset and carrier, not a cloud number product. Distinct from Twilio-class CPaaS.
Free / OSS · AGPL-3.0 · 66 GitHub stars
VerdictMIT edge Web Push lib. Free forever library + playground; you own the delivery stack.
CatchVs Edgepush, Shove, ntfy, Gotify, and Novu: edge Web Push HTTP builder — not a Workers device-push product, not a Go APNs/FCM relay, not self-host pub/sub, not multi-channel workflows. You still implement the service worker, subscription store, and send loop yourself.
