Firefly III
Firefly III ships seven develop builds in six days, still with no changelog attached.
A side-by-side editorial comparison of Finanzfluss Copilot and Stigg — release velocity, themes, recent moves, and the top alternatives to consider.
German personal-finance tracker back to features after a week spent only on bugs.
Finanzfluss Copilot is a German portfolio and budgeting tracker covering brokerage accounts, dividends, budgets and German investment tax. The feed is sparse and uneven: a tax module for Freistellungsauftrag and Vorabpauschale in December, then a five-day Fixit Week in May where the whole engineering team stopped feature work and closed 144 bugs, then near-silence until the August release adding transaction splitting.
Stigg adds credit reservation and settlement for AI operations days after its agent SDK.
Stigg can now reserve credits before an AI operation starts and settle the actual cost when it finishes. It follows the beta Agent Governance SDK, an open-source library built on Stigg's entitlements engine. Earlier October releases added an Airwallex billing backend, credit usage grouped by feature and a Stripe Projects listing.
Finanzfluss Copilot is a German portfolio and budgeting tracker covering brokerage accounts, dividends, budgets and German investment tax. The feed is sparse and uneven: a tax module for Freistellungsauftrag and Vorabpauschale in December, then a five-day Fixit Week in May where the whole engineering team stopped feature work and closed 144 bugs, then near-silence until the August release adding transaction splitting.
The product is being built out along the specifics of German retail investing — allowance tracking, pre-payment tax estimates, broker-specific asset classes — and the Fixit Week reads as an explicit acknowledgement that UI debt had accumulated faster than it was being paid down. Transaction splitting is a standard expectation in this category, so the current direction looks like closing gaps against established budgeting apps rather than opening new ground.
Given the entries here, the likely next step is more depth in budgeting and categorisation now that a transaction can carry several categories; the feed is too intermittent to predict timing with confidence.
Stigg can now reserve credits before an AI operation starts and settle the actual cost when it finishes. It follows the beta Agent Governance SDK, an open-source library built on Stigg's entitlements engine. Earlier October releases added an Airwallex billing backend, credit usage grouped by feature and a Stripe Projects listing.
Credits have become Stigg's main pricing unit, and the product is adapting them to AI workloads whose cost isn't known up front. Reserve and settle, together with the governance SDK, turns the entitlements engine into a spending control for agents.
Expect the governance SDK to use reservations directly for agent limits, and more reporting on reserved versus settled usage.
