Firefly III vs Increase
A side-by-side editorial comparison of Firefly III and Increase — release velocity, themes, recent moves, and the top alternatives to consider.
Firefly III vs Increase: at a glance
What is Firefly III?
Firefly III's feed is its nightly develop builds, not shipped releases.
Every recent entry is a dated 'Development release' — the project's automatic develop-tag pre-releases, each carrying the latest fixes, translations, and in-progress features with an explicit buggy/pre-release warning. There are no stable release notes or feature announcements in the window; the crawler is picking up the nightly build tags.
What is Increase?
Increase ships steady quarterly batches of banking-API primitives, from FedNow to 3D Secure.
Increase is a banking-as-a-service API whose public changelog is a quarterly newsletter bundling many small additions. Recent quarters added payment rails (FedNow, Real-Time Payments, Push-to-Card), card capabilities (3D Secure, a disputes API, push provisioning), and developer ergonomics (multiple SDKs, IP-restricted keys, LLM-friendly docs). The cadence is predictable rather than punctuated by big launches.
Firefly III vs Increase: editorial side-by-side
Firefly III
5.0FINANCE
Firefly III's feed is its nightly develop builds, not shipped releases.
◆ Current state
Every recent entry is a dated 'Development release' — the project's automatic develop-tag pre-releases, each carrying the latest fixes, translations, and in-progress features with an explicit buggy/pre-release warning. There are no stable release notes or feature announcements in the window; the crawler is picking up the nightly build tags.
◆ Where it's heading
This tells us the project ships continuously to a develop channel but the feed surfaces build artifacts rather than user-facing changes. Actual direction isn't readable from these entries — they're timestamps on nightly cuts, not changelogs of what changed.
◆ Prediction
The next entries will be more dated develop builds; a meaningful signal would require the crawler to track the stable release tags or the changelog instead of the nightly develop channel.
Increase
0.0FINANCE
Increase ships steady quarterly batches of banking-API primitives, from FedNow to 3D Secure.
◆ Current state
Increase is a banking-as-a-service API whose public changelog is a quarterly newsletter bundling many small additions. Recent quarters added payment rails (FedNow, Real-Time Payments, Push-to-Card), card capabilities (3D Secure, a disputes API, push provisioning), and developer ergonomics (multiple SDKs, IP-restricted keys, LLM-friendly docs). The cadence is predictable rather than punctuated by big launches.
◆ Where it's heading
The through-line is breadth: Increase is filling in the full surface a bank program needs — more rails, more card controls, more SDK languages, more compliance hooks — one quarter at a time. Nothing here reads as a pivot; it is methodical coverage of the money-movement and card stack.
◆ Prediction
The Q2 2026 digest is the next expected drop and will likely continue the pattern of card, dispute, and SDK additions, though the feed has been quiet since April, so its exact contents are not yet visible.
