5 Free & Open-Source Alternatives to Zendesk

Looking for a free or open-source alternative to Zendesk? Deskly is the closest direct swap — MIT-licensed source on GitHub, or a $49 one-time packaged install. Since you're already auditing what you pay Zendesk every month, here are four more pay-once tools from the same catalog worth a look while you're at it — different jobs, same idea: buy the software once instead of renting it forever.

1. Deskly — replaces Zendesk

Shared inbox, SLA timers, canned replies and CSAT — self-hosted, no per-agent fees. $49 once vs Zendesk's $55/agent/mo. Free on GitHub, or the packaged installer on Whop.

2. Upkeep Status — Components, incident timelines, maintenance windows and email subscribers — self-hosted on a $5 VPS.

Replaces Statuspage.io ($29+/mo). $29 once. See Upkeep Status →

3. Docsmith API — Import a spec and export a self-contained static API reference with try-it-out and code snippets.

Replaces ReadMe.io ($99+/mo). $29 once. See Docsmith API →

4. Vaultly — Bitwarden-style zero-knowledge vaults, shared teams and TOTP, self-hosted with no per-seat fee.

Replaces 1Password Teams ($7.99/user/mo). $39 once. See Vaultly →

5. Secretbox — Projects, environments and versioned secrets with a CLI that pipes straight into your .env.

Replaces Doppler Team ($12/user/mo). $39 once. See Secretbox →

Why this list is worth bookmarking

Every app above is a one-time purchase with MIT-licensed source, no accounts with us and no telemetry. None of them are trying to be the next Zendesk — they're trying to be the last subscription you pay for that specific job.
