SlackVault is a four-surface Slack backup product. The website handles onboarding and archive browsing. A WXT browser extension (Manifest V3) drives the in-browser Slack sync using the user's existing Slack session. A Cloudflare Worker handles OAuth token exchange on the free tier, keeping secrets off the browser. A Slack app manifest centralises scope and permission configuration.
The entire stack is structured to never require a paid backend — Cloudflare Worker free tier is the only operational compute path. Cloudflare secrets follow the workspace `SLACKVAULT_` prefix discipline so the project's keys stay isolated on the shared workspace Cloudflare account.
SlackVault gives Slack workspace owners a way to archive full message and file history without paying per-seat enterprise plans.
