HumHub vs Double: at a glance
What is HumHub?
HumHub's public feed carries only betas, and 1.19's is still about surviving the upgrade.
The four releases visible here are all pre-release: 1.19.0-beta.2 and beta.1, and 1.18.0-beta.6 and beta.5 before them. The 1.19 line is dominated by upgrade-path and data-integrity repair — a foreign key violation aborting the comment content_id migration on databases with orphaned rows, fatal errors when purging content whose underlying record was gone, and in beta.2 a fatal SCSS build loop left behind when the 1.19 move of static/themes into protected/humhub stranded an empty theme skeleton. Beta.2 also fixes a real leak: activities from private spaces appearing in the summary mail and dashboard of users holding only a pending invite or join request.
What is Double?
Double restructures AI pricing with a 93%-cheaper Standard tier, making Ask Double viable at full-book scale
Double is an AI-first accounting platform built for accounting firms managing multiple clients. Over the past two months the product has aggressively extended its Ask Double AI assistant — building workpapers, importing accruals, managing metrics, routing bank transactions from raw PDFs, and now auto-routing queries across a three-tier model stack. The Sep 10 model restructuring is the culmination: with a Standard tier 93% cheaper than Expert and an Auto mode that routes per-query complexity, Double has shifted AI accounting from a premium add-on into an economically viable default across every client account. The interactive financial statement suite — P&L, Balance Sheet, and Cash Flow — is now complete.

HumHub
5.0COLLAB
HumHub's public feed carries only betas, and 1.19's is still about surviving the upgrade.
◆ Current state
The four releases visible here are all pre-release: 1.19.0-beta.2 and beta.1, and 1.18.0-beta.6 and beta.5 before them. The 1.19 line is dominated by upgrade-path and data-integrity repair — a foreign key violation aborting the comment content_id migration on databases with orphaned rows, fatal errors when purging content whose underlying record was gone, and in beta.2 a fatal SCSS build loop left behind when the 1.19 move of static/themes into protected/humhub stranded an empty theme skeleton. Beta.2 also fixes a real leak: activities from private spaces appearing in the summary mail and dashboard of users holding only a pending invite or join request.
◆ Where it's heading
The 1.19 cycle is being spent making the migration survivable on real installations rather than adding capability, which is the usual shape when a schema and directory-layout change meets databases and webroots that have accumulated years of drift. Beta.2 extends that into the installer itself, where an unreachable database was offering to re-set-up a live instance during a transient outage. The permission and visibility fixes point the same way: tightening authorisation and content boundaries is cleanup of an existing model, not an extension of it.
◆ Prediction
Only beta tags appear in this feed, so a 1.19.0 stable is the obvious next milestone, but nothing here dates it. The beta.1-to-beta.2 gap of about a month is a faster rhythm than the roughly six months between the 1.18 and 1.19 betas.

Double restructures AI pricing with a 93%-cheaper Standard tier, making Ask Double viable at full-book scale
◆ Current state
Double is an AI-first accounting platform built for accounting firms managing multiple clients. Over the past two months the product has aggressively extended its Ask Double AI assistant — building workpapers, importing accruals, managing metrics, routing bank transactions from raw PDFs, and now auto-routing queries across a three-tier model stack. The Sep 10 model restructuring is the culmination: with a Standard tier 93% cheaper than Expert and an Auto mode that routes per-query complexity, Double has shifted AI accounting from a premium add-on into an economically viable default across every client account. The interactive financial statement suite — P&L, Balance Sheet, and Cash Flow — is now complete.
◆ Where it's heading
Double is building toward a full AI-agent accounting platform, not just a chat interface bolted onto bookkeeping software. The AI Agents private beta (automating recurring tasks on a schedule or event trigger), the MCP/API surface for programmatic control, and the Connections feature (reaching into Slack, Notion, HubSpot) all point to Double becoming an orchestration layer for accounting firms. The model pricing restructure signals that Ask Double is expected to run on virtually every client action, with human review reserved for exceptions rather than the default. The direction is clear: make AI the primary work surface and treat the accounting firm's judgment as the final gate.
◆ Prediction
The next move is most likely graduating the AI Agents beta to general availability — converting scheduled automation and event-trigger workflows from a differentiated beta into a standard tier feature. Expansion of the Connections library beyond Slack, Notion, and HubSpot is also probable, since cross-tool context is a prerequisite for agents to make decisions autonomously.
