Elgg vs Double: at a glance
What is Elgg?
Elgg 7.1.0 adds invitation-only groups and designates MariaDB as its primary database
Elgg is a mature open-source PHP social networking framework used primarily for self-hosted community platforms. The 7.0 major version shipped in May 2026 and introduced system-level IP logging, accessibility improvements, and a generic entity controller. Since then the 7.x branch has been in a stabilization phase — the team maintains both 7.x for current users and the 6.x branch for security backports, with coordinated dual-branch release patterns visible across the changelog.
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.

Elgg 7.1.0 adds invitation-only groups and designates MariaDB as its primary database
◆ Current state
Elgg is a mature open-source PHP social networking framework used primarily for self-hosted community platforms. The 7.0 major version shipped in May 2026 and introduced system-level IP logging, accessibility improvements, and a generic entity controller. Since then the 7.x branch has been in a stabilization phase — the team maintains both 7.x for current users and the 6.x branch for security backports, with coordinated dual-branch release patterns visible across the changelog.
◆ Where it's heading
Elgg 7.1.0 moves in two directions simultaneously: infrastructure positioning (MariaDB as the explicit recommended database for self-hosted deployments) and access control granularity (invitation-only group membership, admin-only menu items in entity actions). These are consistent investments in making Elgg viable for communities that need fine-grained permission models. The dual 6.x/7.x maintenance cadence reflects a conservative community that upgrades slowly and values stability over feature pace.
◆ Prediction
Continued dual-branch maintenance with 7.x accumulating incremental access control and entity management features while 6.x receives security backports. Given the 7.1.0 MariaDB recommendation, database-specific optimizations or stricter compatibility requirements for MariaDB are a plausible next step.

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.
