Betaflight vs Slurm
A side-by-side editorial comparison of Betaflight and Slurm — release velocity, themes, recent moves, and the top alternatives to consider.
Betaflight vs Slurm: 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 Slurm?
Slurm's 26.05 line settles into routine fixes after September's seven-CVE release.
Slurm maintains three branches (25.05, 25.11, 26.05). On September 2 it shipped coordinated security releases on all three fixing seven CVEs, including an operator-to-administrator privilege escalation and SQL injection via cluster names. 26.05.5 on October 13 returned to ordinary fixes: qstat -f output, a slurmd double free and powered-down nodes placed incorrectly. 26.05.3 in August added external nodes in heterogeneous jobs.

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.
Slurm
2.5DEVOPS
Slurm's 26.05 line settles into routine fixes after September's seven-CVE release.
◆ Current state
Slurm maintains three branches (25.05, 25.11, 26.05). On September 2 it shipped coordinated security releases on all three fixing seven CVEs, including an operator-to-administrator privilege escalation and SQL injection via cluster names. 26.05.5 on October 13 returned to ordinary fixes: qstat -f output, a slurmd double free and powered-down nodes placed incorrectly. 26.05.3 in August added external nodes in heterogeneous jobs.
◆ Where it's heading
The 26.05 line, which introduced SLUID identity and an in-tree TLS path in May, is past its security scramble and into routine point releases. Older branches get backports only when a security fix requires it.
◆ Prediction
Expect 26.05.6 on a similar monthly pace with reliability fixes; another coordinated security release would again cover all three branches.
