Betaflight vs Groonga: at a glance
What is Betaflight?
Betaflight grew a real autopilot: waypoint missions, geofence RTH and MAVLink ground control
Betaflight runs two lines at once. The 2025.12.x branch is maintenance: UART interrupt handling, MSP race conditions, failsafe clamping and board-target refreshes. The 2026.6 line, released as 2026.6.1 in August, carries an AUTOPILOT mode with flight plans, CLI waypoint commands, geofence return-to-home and LAND loiter, plus a DroneCAN stack and MAVLink ground control. 2026.6.2 in September backported a single I2C guard fix.
What is Groonga?
Groonga is putting a full-text search engine into WebAssembly and the browser.
Groonga ships every one to three weeks, and the 16.1 line has a clear thread: experimental WASI support. 16.1.2 added a WASI groonga command and a browser build that downloads a database over HTTP on demand, 16.1.4 extended WASI to tokenizer and normalizer options, and 16.1.5 linked plugins statically so they work under WASI. Alongside that, 16.1.1 made logical_select run shards and drilldowns in parallel, measured at 1.5x faster with two workers.

Betaflight grew a real autopilot: waypoint missions, geofence RTH and MAVLink ground control
◆ Current state
Betaflight runs two lines at once. The 2025.12.x branch is maintenance: UART interrupt handling, MSP race conditions, failsafe clamping and board-target refreshes. The 2026.6 line, released as 2026.6.1 in August, carries an AUTOPILOT mode with flight plans, CLI waypoint commands, geofence return-to-home and LAND loiter, plus a DroneCAN stack and MAVLink ground control. 2026.6.2 in September backported a single I2C guard fix.
◆ Where it's heading
The autopilot work is not a single feature but a rebuild of how the firmware handles position: the release notes show position control unified on a velocity primitive and the existing GPS rescue reimplemented as a flight-plan mission rather than a special case. That direction pulls hardware integration along with it — DroneCAN node allocation, GNSS Fix2, ESC telemetry and MAVLink ground-station handshaking are all things a manually flown craft does not need. The SITL harness gained fidelity and per-run session ids in the same releases, which is what you build when autonomous behaviour has to be regression-tested rather than test-flown.
◆ Prediction
With GPS rescue now running through the mission engine, the next releases on this line should concentrate on hardening that path — the release candidates already added an rx-loss policy, sanity checks and an arming gate for flight plans, and safety scaffolding of that kind usually keeps accumulating after the feature ships.
Groonga
5.0DEVOPS
Groonga is putting a full-text search engine into WebAssembly and the browser.
◆ Current state
Groonga ships every one to three weeks, and the 16.1 line has a clear thread: experimental WASI support. 16.1.2 added a WASI groonga command and a browser build that downloads a database over HTTP on demand, 16.1.4 extended WASI to tokenizer and normalizer options, and 16.1.5 linked plugins statically so they work under WASI. Alongside that, 16.1.1 made logical_select run shards and drilldowns in parallel, measured at 1.5x faster with two workers.
◆ Where it's heading
The WebAssembly work is moving piece by piece from the core command to options and plugins, which points toward a usable in-browser search engine. Every WASI item is still marked experimental and not stable.
◆ Prediction
Expect more WASI coverage in the next 16.1.x releases, with the experimental label likely to stay for now.
